2. THE DUG POPULATION IN URBAN AND RURAL AREAS

2.1 Introduction

Any decision made by responsible aucu or i t i es concerning dog rabies controlshould be based on cost-benefit analysis. Cost Hnd benefit of particularcontrol strategies cannot be estimated without knowledge about the involvementof different species in the epizootic, the size and turnover of the dogpopulation concerned, the degree of supervision of owned dogs, the proportionof unowned animals in the dog pcpulat ion, the origin of unowned dogs, theaccessibility of dogs for c ontrol and vaccination campaigns and the publicattitude towards dogs anc con t r o I measures. Also of great importance is anunderstanding of the habitat with its man-made resources (food, water,shelter) supporting a variaole number of unowned and owned unsupeeviseddogs. Part of the information can be gathered by simple means (e.g.questionnaire surveys) but the majority of data needs establishing bytime-consumirrg field observations using wildlife techniques. These effortsare not purely academic; on the contrary, they will lead t.o the selection ofoptimal strategies of disease control. Before discussing more complex studiesa few suggestions will be made in the following section on how someinformation on the dog po pu l a t i on paeameters can be obtained by simple mean s ,

Information collected. by ~hese simple methods may suffice foradministrative purposes and ? ussib ly for the planning of rabies conteolcampaigns. More precise knowledge is not easy to obtain. Nobody expectsthat the biology of rabies virus can be elucidated by anybOdy except avirologist. The genome of a dog is about 100 000 times bigger than that of arabies virus. The dogs morpholo gy, physiology and behaviour acecorrespondingly more complicated. Unfor.tunately zoologists have been slow tostudy domestic animals. the following pages are intended to stimulate theieinterest. Suggest ions are made conc ern i.n g h ow several different andfascinating questions can be t Bckl ed by us ing methods of wildlite reseaech andfield anthropology. The acquisition of new t:.nQwl edge concerning theabundance, habitat requirements, movement, dynamics and behaviour of dogs,along with sociological Qa:a regarding dog-human relationships, will eesult 1na significantly better understanaing of:

a) the incidence nnd persistence of dog rab ies in urban and rural communitiesin relation to dog population densities and de mography

b) the parameters of physical environments responsible for variable dogpopulat ion densities, the. conu i t i ons under which suscept i b le dogpopulations occur and the ecological requirements necessary to sustainthese populations

c) the relationship between dog movement, dog social interactions, and rabiestransmission between indi.viduals within populat ions and the spread of thedisease into new areas

d) regional or local sociological and cultural practices that result i.n thepresence of dog populations susceptible to rabies and cultural activitiesleading to endemic dog rabies situations

e) dog demography, ecology, behaviour and human cultural practices as relatedto the effectiveness of dog control and rabies vaccination prograr.~es.

2.2

Very few urban or rural dog population studies have Deen published, andnone have had as major objectives the relationship between dog ecology andbehaviour, human cultural attitudes and the occurrence of rabies in dogs.However, several describe methodologies for the collection ot data relating todens ity es t imates, demography, rnovement, social interact ions and behaviour,and sources of food and shelter. :-lost of the methods used to obtain thesedata were adapted from previously developed techniques for the study oiwildlife species in natural habitats. Hany wildlife techniques may be usedor modified for studying urban or rural dog populations. Publications andjournals that summarize or publish wildlife techniques and indexed wildlifebibliographies are available in many university or public libraries and atbiological research centres. Because the study of dog populations hasreceived little attention, virtually no standardized field techniques areavailable that h~ve been proved, through replication, to reliably measurevarious population parameters. Thus, a great need exists tu develop andevaluate such techniques using pilot studies that can lilter be expanded uponand applied in a number of areas where clog rabies is a problem. For thesereasons, it is not feasible to present specific and detailed outlines torconducting population studies. The following guidelines are thereforeintended to serve as a basis for the design ot field studies that willhopefully result in practical protocols for future use.

The following sections on the difterent aspects of dog ecology include ashort introduction, a summary of available techniques to investigate therespective aspects and a brief review of the actual knuwledge. In theintroduction the problems are defined. A few indications of theirsignificance for practical dog or disease control are given. Information onthe subject is usually gained by two different typ es ot approach. Oneap proacn uses the t ech n i que s 0 f wi Id 1i f e b io logy, the 0 t he r t he methods 0 fanthropological or sociological inquiries. The methods for investigatingwildlife populations and wildlife habitats are continuously improved. Thefourth edition of the "Wildlife 'Ie chn i.quc s ManUlll" (Schemnitz, 1980) coversthe present state of the art. Comprehensive guidelines for the elaborationof questionnaires and their use in surveys do not exist so far. Useful hintscan be found in the "Interviewer's !'lanual" published by the Institute forSocial Research in Ann Arbor (1969) and in Sellitz et al. (1976).Questionnaires for gathering dog population data and for assessing humanattitudes towards dogs have to be designed very carefully in order to getinterpretable answers and to minimize ambiguity. Questions should beformulated so that people are not tempted to answer what they think theinterviewer would like to hear. The majority of stUdies published onecological aspects of dog populations were done in North America. Somecultural aspects of dog-man relations wer e also recorded in other areas, e.g.,in Africa (Frank, 1965), Australia (Meggitt, 1965), and Polynesia (Lu omaI a ,196D) •

2.2 A short pr op r o mn:e tor the cullection or information on dog populationsand some general considerations

The most important items of information on dog populations for planningand surveillance of rabies control measures are as f o l l ows :

a) Abundance

Wh ere the number 0 f owned cl ogs is no t reg is t cr e d by 1 i ceus i ng, it may beestimated by questionnaire surveys. An example of an abbreviated surveyque s t i orma i re is in Anne x 2.4. Ca re h as to be taken t ha t rand ornl.y se lee tedrespondents from representative human ropulations are interviewed. A minimumnumber 0 f unowne d or unsupervi s eel dogs c an be est ima t ed by s tree t count s , In

order to do that representative districts of the areas under study have to bechosen. These can be a number of streets, or quadrants. In these sampled i, s tr ictsaIl dogs lUUS t be counted dur ing the time whel1 th e max i mum numbe r ofindividuals is active and visible. If a known number of dogs wearing collarsor tags is in the sampled sections, a much more precise census can be made.For details see Section 2.3.1 of this chapter.

b) Ratio of owned versus unowned dogs

It is ~mportant to know t he ratio in order to estimate the percentage ofdogs accessible for vaccination. A ratio can be calculated if the number ofowned dogs is established an~ ene total population is reasonably wellestimated by coraprefle~sive investigation le.g. by marking and recapture).Another most simple proce dure estimates the two classes of owned and unowneddogs in an area through enqu iry.

One might a s s ume that people are well awa r e or the dog s i.t ua t i.on in theirneighbourhood. Selected respondants may be nskec toe following questions;

how many dogs are i~ your neighbourhood?

how many oi them <ire owned by yourself, how many by your neighbours?

how many are unowned?

(or; what perc~ntagc of dogs you see ~n your neighbourhood areunowned dogs?).

c) Dog population turnover

This information is important. for determining the frequency of vaccinationcampaigns. Facts on reproduction and longevity of owned dogs can be gatheredby questionnaire (see Annex 2.3 for example). Some (possibly biased) data onthe age structure of stray dog population can be obtained by examining thetooth wear of killed or impounded stray dogs.

2.3 Abundance

Dog abundance is related to different epidemiological situations, todifferent culture areas, to different rural and urban habitats, to areas ofdifferent human settlement patterns and also to different social strata ofhuman rural and urban populations. Vog population density is commonlyindicated as a dog to human ratio, occasionally also as dogs per household.In many situations it would be more meaningful to express it as the numbers ofdogs per unit area, or to have lt related to both surface a r e a and humanpopulation.

The practical importance of investigating dog population sizes seemsclear. The knowledge of the numbers of owned dogs and of the abundance ofunowned dogs is a prerequisite for the plann ing of animal control andvaccinatlon canlpaigns and for epidemiolog ical and ecological studies.

2.3.1 Techniques

The numbers o f owned dogs may be e s t ab l i.sh ed by que s t i ouna i re s ur vey s , or­from the records of licensing of dogs (Schurrenberger et a L, , 1961; Har x andFurco l ow , 1969; Kelly, 1980; NiJSS8r and Mosier, '1~80; Rangel et al., lY81;WHO studies in the Philippines, in the US-Mexico border area, a n d i n NorthAfrica) or during dog vaccination campaigns (~eran et al., 1972). If thereis any indication that a sizeable proport ion of a dog population escapes thesecensusing procedures, the techniques used for estimat~ng wildlife abundancehave to be applied. Various methods are ava iLab Le for estimating the numberof free-roaming carnivores, all of which are based on two assumptions(Caughley, 1977; Davis and Winstead, lY80);

that mortality, emigration and recruitment into the population areminimal durlng the period of census, or that corrective factors canbe incorporated into resultant estimates.

that all individuals within the population to be estimated have anequal chance of being counted.

Techniques that can be used to obtain estimates of dog densities include:

a) Total or direct counts. This method s imply consists of makingdirect visual counts of individual dogs i n a defined geographical area andwithin a limited period of time in order to meet the assumptlons mentioneaabove. Direct counts are not practical over large geographical areas norin sizeab le cities but can be used in small co~nunities and ruralsituations where dog populations are small (Gipson, 1982). Und er certainconditions, estimates of dens ity may also be ob tained by counting dogsalong stratified samples of randomly selected streets or in quadrants.These data can then be extrapolated to the entire study area. If th ist echnique is used, it is - important that statist ical expertise be obtainedto determine appropriate sampling procedures and data analyses. In somecircumstances, data derived from this technique (and several other sdiscussed below) may also be used to compare dog densities between areaswhen expressed, for example, as the mean number of dogs observed per unitof land area (e.g. dogs/hectare).

b) Es t imates from rate 0 f capture. As suming certa in cons tr a in t s suchas a closed population, equal intensity of capture efrort and probabilityof capture, and unvarled environmental conditions, estimates of dogpopulations can be obtained by plottlng on graph paper either the sum ofdaily captures, the cumulat ive sum of captures, the probab i l ity ot

capture or the catch-effort required. Plots can be smoothed andlorextrapolated to provide estimateo of dog population size. More com~lete

explanations of these procedures and examples of each are shown in chapter 14of a wildlife techniques manual published by the Wildlife Society \~Che~l~tz,

1980; Davis and Winstead, 1980; see also Caughley, 1977, and Annex 2.3).Studies are needed to determine if these techniques could be used inconjunction with stray dog elimination programmes.

c) Es t ima tes from recaptun:s . The re 1 iab i.I ~ ty 0 f thes e tech niques aredependent upon the same constraints as mentioned in (b) above. They arecommonly known as the "Pe t c r s orr-u ack s on" or IILincolnu index ana are basedon the use of a simple ratio obta~ned by capturLng a number ofindividuals, marking 0r tagging them, and releas!ug them back into thepopulation. The popu~ation is subsequently sampled again by trapping andthe total dogs caught and the numbers that are marked are determined.The population estimate is thell obtained ;;.s follows:

or

Estimated dog population

No. dogs caught, :narkedand released

No. dogs subsequently caught

No. marke d dogs recaptured

No. dogs initially trapped,uarked and released x Total no. of dogs

subsequently caughtEstimated

dog populationNo. marked Jogs recaptured

The s t a t i.s t i.c a I procedure currently described as t.n e mos t suitablefor analysis of capture-recapture datQ should be consulted (Jolly, 1965;Caughley, 1977).

Dogs in urban areas do not have to be phys!cally captured in order tomark them. Studies in Baltimore, MD and Newark, NJ, USA (Beck, 1973;Heussner et al 1978; Daniel,;, 1980) used a method whereby dogs were"marked" by photographing tnem. Subsequent sampling then determined thenumber of "recaptures" on any given day based on the number of dogs thathad been photographed previously. In these studies a modification ofSchnabel's statistical analys!s for multiple recaptures (Day et al., 1980)was used (Hanson 1967, 1968; Beck, 1Y82; see also Annex 2.3). Thistechnique has the advantage of reducing sampling error since captureratios are averaged.

The Baltimore study (Beck, 1973) enployed several alternate methoasfor estimating dog abundance and compared the numerical values derivedfrom each as a measure of their validity (Anilex 2.3). Such comparisonsare recommended when uncertainty exists as te wni cn method of populationestimation is most suitable for a given situation. While thephotographic multiple recapture method may be suitable for smaller areaswhere the dog population consists of mixed breeus and indivlciuals can bedistinguished on the basis of colour, identifying markings and size,native dogs in SOme geographic areas are more physically uniform inappearance and distinguishing individuals would be difficult orimpossible. In such areas, physically marking Lnd iv adua Ls may be

necessary. Depending upon local acceptance, this can be done in urbanareas, where dogs are less wary, by using a commercially avallablelivestock-marking pistol that fires paint balls containing differentcolour paints. COz-activated rifles that fire a dart containlng amarking paint are also available. Tree marking paint can be propelled 1na stream for considerable distances using a hand-held squirt can.Another way to mark dogs for later derivation of population estimates isto place permanently affixed coloured collars on dogs at the time rabiesvaccination programmes are implemented. Subsequent observations can bemade to gather data for calculating density estimates and these data canalso be used to determine the percent of free-roaming dogs that have beenvaccinated (i.e., programme efficacy). A number of other techniques forpermanently or temporarily marking wild mammals have been described andsummarized (Day et al., 1980), some of which could be used to mark dogscaptured in rural habitats. The semi-permanent marking ot claws and hairby oral ingestion of a bait c ont.a i n i.ng rhodamine B (Johns and Pan, 1982),and marking the blood with oral (via baits) administration of an iod1uecompound (iophenoxic acid) or mirex (Larson et al., 1981) have beendescribed for wild c an i.d s but nol I'o r domestic dogs. The latter twotechniques may have application providing that the number of dogsconsuming treated bait is known.

d) InJices. These techniques involve establishing a relationshipbetween the numbers of animals present in an area in relation to somemeasureable envl.ronmental factor. So far the only published attempt toestablish relative figures of dog abundance and distribution in a cityus ed th e numb er of sigh t ings 0 f dogs at large by school eh ildren inBristol, United Kingdom CHarris, 1981). Examples of indices used forwild canids are the nunilier of dens observed per unit of land area(dens/hec tare), the number 0 f tracks c oun ted cross ing roadways(tracks/kilometer), and the number of canid visitations to odour or"scent" stations placed out at regular intervals and checked daily fortracks left at stations (station night/visit) (~oughton and Sweeny,198Z). While such techniques were developed for application in ruralareas, modification for urban use to obtain indices of relative dogabundance may be feasible. For example, the removal or marking of alldog faeces along sample roadways and subsequent counts of fresh orunmarked deposits for a set number of days (no. faeces/km/day) immediatelybefore and after an intens i ve s tr ay dog e I imina t ion progr amme , may be afeasible technique. The difference between the number of old and newdeposits should be directly proportional to the reduction in street dogsand thus provide an indicator of the percentage of dogs removed, eventh ough th e size 0 f the original popuLa t ion was unknown , Another indexwhich could p6ssiblybe used is the widely recorded frequency of reporteddog bites in relation to the dogs present in an area. But this figuredepends on a great variety of factors (Marr et al., 1979). Indices ofrelative abundanc p senerally require less effort to obtain than actualdensities and are particularly valuable for determining changes inpopulation size over time or for comparisons between envirollluentallysimilar areas. As with all other techniques previously discussed,certain assumptions must be made in order to obtain valid indices.

The density and distribution of dogs, whether in urban or rural areas,will vary depending upon environmental factors, availability of tood, waterand shelter, and human cultural pract ices and customs. Because ot thesevariations, tbe selection of sampling "units" or met.h od s of stratification ofstudy areas, the results of which are later extrapolated to estimate totaldensities, must be carefully considered.

2.7

For example, the commonly used procedure of sampling to obtain a dog to humanratio and applying it to the tot~l human population in a city to estimatetotal dog nuniliers, does not take into account variations in the frequency ofdog ownership as a result of such factors as economic status. Samplingprocedures are therefore an extremely important component of populatlonestimation t e chn i.que s ,

While a number of methods are commonly useCl to estimate wildlifepopulation densities in natural habitats, silnilar procedures for dogpopulations have not been adequately eval~ated. Thus, further research isneeded to devise standardized procedures that can be used in a wide varietysituations.

2.3.2 Observat ions

of

Reliable estirr.stes fer dog popu1ations are still r~re. In general,American and Eur opean coun tries report a dog to human r a t i,o between 1: 10 and1;6. But there is no doubt t h a t the a bundance of dogs v a r aes considerablyfrom country to country and witnin geographical regions within countries. Astriking example is given by ~zeokoli et al. (1982) for Kaduna State inNigeria. In northern Kaduna State there is less than 1 dog per lOtiOinhabitants, while in souther'l parts of the same state tne dog to human ratiolies between 1;27 and 1:3. In different areas of Mexico City the ratiovaries between 1: 10 and 1;1 (Ra ng e I et al., 1981). In developed countriesthe variation of the pet do g ropulation is usually airectly related to theincome and the vigour of the economy (Franti et a L, , 1974; Purvis and Otto,1976). As a general rule, the ratio of owned dogs to people is greater inthe more rural regions of a country.

In urban areas of ~orth America and Europe the breeding success ofowner less dogs is very low (Beck, 1973). In these cities the s tray dogpopulations are the product of released, lost, and abandoned owned animalslBeck, 1973, 1974, 1975). In the same cities, most dogs found free rangingare owned, but unsupervised, animals. As a general rule in urban areass tr ay ing or loos e pe t 5 are tnor e c ornmon in 1ow- Lncome higher dens ity areas,while ownerless stray dogs are r,lOre.:::ommOrr ::'0 l ower human density areas (Beck,1973, 197 /+; see also Rangel et a1., 1981; Har ri s , 19(1). In study areas ofBaltimore, Maryland, USA (Beck, 1973 ) a nd of Ne.wark, New Jersey, USA (Daniels,1980) the density of street dog populations (stray dogs plus loose pets) wereestimated to be approximately 150 per square km. The density and origin of "street dogs in ~ities or subtropical and tropical areas may be different fromthe situation described aoove.

Very little is known BDout the abundance of unowned stray and feral dogsin rural areas. A few reports indicate that uuo~led dogs in rural areas arefound wherever they are looked for (McKni~lt, 1964).

2.4 Habitat

Dogs inhabit a great variety of different habitats. An analysis of thesehabitats should reveal the abundance, d i s t r ibu t i on and predictability ofresources (shelter, water, food ) for dogs. Once tne resources determiningthe carrying capacity of a habitat are known, ie ~ight become possible toinfluence dog abundance by habitat control e.g., by removing an important foodresource.

2.8

Considerable effort has been devoted to defining and quantifying wildlifehabitats and relating habitat quality or "carrying capacity" to animaldensities and distribution (Gysel and Lyon, 1(80). However , similarparameters and techniques for evaluating dog habitats at"e lacking. Oneobvious difficulty, at least in urban areas, is that one segment of the dogpopulation may be ownerless and completely free-roaming, thus relying entirelyon the availability of shelter, food and water found on the street; whereasthese needs are wholly supplied to another segment of tbe population by theirowners. Ranging between these two extremes is a third component of thepopulation whose requirements are met in varying degrees by both street andowner. Another problem complicating habitat analysis is that culturalpractices may also vary widely, even within the same city, and this factorwill greatly influence the quality and quantity of habitat, food and shelter.

Some of the more specific elements that comprise dog habitat in urbanareas are

Shelter. Number of vacant buildings access t.b le to do gs ; landfills, dumps, parks, open space (including types of vegetation andpercentage vegetated); streets, alleyways, parking lots; percentageof land area comprising private residences, apartments, retailbusinesses and industrial sites; number of resting or loafing areas(i.e., porches, stoops, stairs, passages, garages, yards, roofs,loading areas, etc.).

Water. Number and extent of naturally occurring sources of water(springs, streatus, rivers, lakes, standing rain water); man-madesources (fountains, piped sources, leaking hydrants, livestockwatering tanks or wells, water placed out tor dogs).

Food. Number and size of garbage dumps and land fills, garbagepiles left in street or in containers accessible to dogs, frequencyof garbage collection, commercial open food markets, food handouts byhumans.

2.4.1 Techniques

A great number of systems for the classification of natural and ruralwildlife habitats has been published (GysE'.l and Lyon, 1980). The growingneed for' an under standing 0 f the urban env ironment has also 5 timu la ted fir s tinventories of urban wildlife habitats (Matthews and Miller, 1980, Annex2.5). None of the classification systems has universal application and noneof them has been tried for dog habitats. While no attempts have been made toquantify urban dog habitats, the guidelines and steps suggested for wildlifehabitat analysis will be helpful (Flood et al., i977; Gysel and Lyon,1980). Detailed maps of the area must be obtained or drawn; those preparedby urban planners are particularly useful. Based on aerial photographs(where available) and ground .reconnaissance, major land use types aredelineated, plotted on maps and area sizes encompassed by each are determinedand their occurrence expressed as a percentage of the total availablehabitat. The locaiion of other important elements of habitat such as largevacant buildings, water sources, dumps, open markets, etc., are also shown.Where open areas occur, type, height and density of vegetation should bedetermined and placed on maps. Use of colour codes, symbols or keys arehelpful when mapping various features of the habitat. The information shownon maps can then later be organized and arranged in tables and graphs, andstatistically analyzed manually or by computer. Such maps can be used as abasis for selecting sample roadways, plots, or quaur ant.s within the en t i.r e

urban area for intense studies of more specific features of the habitat laswell as for representative analysis of dog population " p "~r ame ters ) . Aspre~iously mentioried, the collect~ou of data fr6miarge areas is frequentlyimpractical because of limited fundS or manpower. Detailed habitat mapspermit the systematic selection of siu\ilar (or dissimilar) sampling units sothat quantification and statistical analysis of data are possible. The~r usealso enhances the potential for extrapolating the data to the entire studyarea which, in turn, permits generalizations concerning habitat and dogpopulation parameters to be formulated.

2.4.2 Observations

Some major components of the environment that are determinants of dog 0

habitat (and thus their density and di$tiibut~on) are:

a) Climate. Harsh climates and particularly cold, winter weather, butalso extreme heat, tend to make survival more difficult, resulti~g 1nlower free-roaming dog dens ities (Dani.e l s ; 1980). "

b) Shelter. The urban environment contains numerous areas where dogscan find cover and protection against adverse weather con~itions,

people and other animals, while resting, sleeping or whelping. "oTheavailability of shelter in urban areas appears to be determined in "large part by the economic status and density of the humanpopulation. As ment ioned under Section 2.3.2, dog densities aregenerally h i gne r in densely populated areas where incomes are low.Sites offering complete cover include vacant buildings and garages,as well as those under construction, and passages "and "common areas ofocc,upied structures (Fox et °a l. , 1975). There are also numerous "

"t opogr a ph i c features that offer some "protec t ion agains t the elements'including disused densely vegetated areas, woodlots, dumps, bUllding

's t ruc t ur e s , porches and other o~erhanging structures. Parked car"sand trucks are also routinely used (Beck, 1973, 1974, 198Ua;Daniels, 1980). ' Th e rural environment contains many similarstructure~ as ~ell as larger woodlands and fields ~nd naturaL :cavesand dens;Scoti and Gausey, i973). It should be remembered thatthe general social acceptance of dogs permits them to use areas whichare not av~ilable to wild animals or pest ~pecies (Beck, 1973, 1980a).

c) Water. while availability of water in most areas is not a limitingfactor, water in arid habitats may be so limited that "dogs are [arcedto e i.ther move elsewhere or numbers are l"imited.

d) Food. Availability of food for free-roaming dogs is probably one ofthe TIIOSt important factors influencing den~ity. In urban as well asin rural areas garbage from individual homes, at market places, or atcentralized dumps is a major source of food for dogs.

e) Cultural" practices and customs. Human affection for, or toleranceof, both owned and unowned dogs, religious beliets, use and disposalof natural and man-made r es ou rce s , and 1 iving condi t i ou s , to mentiononly a few factors, directly or indirectly influence the quality andquantity of shelter, food, and water required to support dogpopulations.

f) Dog interactions. The densities of many wild canids ar~ regulated,at least in part. by social interactions between individuals, fam11ygroups or packs. To what extent such relationships limit dogdensities in relation to available habitat is unknown • .

2.5 Dog movements

The analysis of the use of space by a mammal includes the investigation ofactual individual movements to feeding places, shelter, breeding places,females in heat, etc. Daily movements within a home range or territory mustbe distinguished from dispersal movements. In mammals, most ·d i s per sa 1activity occurs in a short period before or at sexual mat.ur i t y , Thedispersal movement leads away from the place of birth or from the parents toanother place or group. This is much more complicated in dogs. Dailymovements of dogs may be directly influenced or controlled by JUan through partor full time confinement to buildings, fenced yardS, etc., and throughtransportation and conduct by leash and obedience. The dispersal of owneddogs is entirely directed by man or dependant on hwnan migratory movements.Owned, but also unowned dogs may follow human nomads. Knowledge of thesemovements is important for the understanding of the epidemiology of dogdiseases and of diseases transmitted from dogs to man and to livestock.These observations have their practical application when consideringquarantine measures.

2.5.1 Techniques

Owned dogs and urban stray dogs are often individually recognizable,mostly diurnal, and relatively tolerant of human proximity. The· movementsand the use of space of such dogs can be tracked by direct observation (Beck,1973; Fox et a1 1975, Daniels, 1980; Rubin and Beck 1982). The use ofspot 1 ight s and dog collars made 0 f 1 igh t -re fleet ing materials, or collarscarrying battery-operated "pin" lights or beta lights. can be used tofacilitate night-time observation of dog activity and movement. Unowneddogs, especially feral dogs in rural areas, are often more secretive. ~or

secretive wild canids radio telemetry is commonly used to obtain movement,home range and activity data (Amlaner and MacDonald, 1979; Cochran, 1980).This procedure consists of placing battery-powered radio transmitters affixedto collars on individual animals. Signals emitted by transmitters arereceived on small, portable or fixed-location.receivers equipped with areceiving antenna. The animal's location is fixed by triangulation~ Thetechnique has been used to study feral dogs in rural areas (Scott and Causey,1973; Nesbitt, 1975; Gipson. 1982), but not for investigating spaceutilization .by urban dogs. However, red foxes in an urban area have beenstudied in this manner (liarris, 19~O). Telemetry equipment is commerciallyavailable from a number of sources and, while costly, it offers certainadvantages over direct observations. Locations of a large number ofinstrumented individuals can be easily determined at frequent intervals, bothnight and day, and small. home ranges would. permit the use of small sizetransmitters concealed in collars. Transmitters can be constructed so thatchange? in animal activity result in different transmitter signal pulserate s • Thus, per a.ods of res t ing and movement; can be d i.s t inguished. Somecountries have regulations for the use 6f telemetry equipment,frequency bandsand power output of transmitters. . ..

Other methods exist for stUdying dog movements. A number ofdistinctively coloured non-toxic dyes and reflective and fluorescent pigmentsfor the marking of animals can be placed in edible dog baits (Day et al.,1980; Johns and Pan, 1982). Baits can also be loaded with coloured plastic

markers or metallic paint particles, which do not disintegrate and arere:~H.Jrbed 'dui 'i'ng ' th e 'i n t e's t ina1 passage (Wande ler et a 1. ', 1975).

The occurrence, location andfrequ~hcy of mrirk~d 'faeces within given ~ime periods would' indicate movementand distribution. If , iridividual baits contain distinctmarkers,a morecomplex, 'ba i t lay-out pattern may be chosen. The use of baits containingmarkers has been investigated for assessing the potential effectiveness ofcontrol by toxicants and chemosteri lants, and the oral adnri.n i.s t r a t i on o frab ies vaccine (Larson et al., 1981).

2.5.2 , Obser'vations

In a study in Baltimore, Maryland (USA), 40 percent o f.all dogs observedwere in alley s, 21 percen t in the s tree t and 19 percent on s te ps or s idewa lk s .

The home range of North American urban dogs has been est imated us ingcontinuous observation and plotting methods; a range of 26 hectares has beenreported in Baltimore, Maryland (Beck, 1973; 1975), 52 hectares in St. Louis,Missouri (Fox et a1., 1975), 4 hectares in New York lkubin and Beck, 1982) >

and only 0.7 hectares in Newark, New Jersey (Daniels, 1980). The home rangeof partially restrained dogs, that is dogs permitted freedom for only a smallpoiti~n of th~ day, is smaller than for pets that are permitted freedomcontinuously. 'The home range of unowned dogs in rural areas appears to beconsiderably- larger. Packs composed of 2 to 5 adult feral dogs in Alabama(USA)' used home -r ange s between 444 and 1050 hectares (Scott anaCausey,1973).- The range of a feral dog pack in Illinois (USA) included nearly allofj2850 hectare portion of a wildlife refuge (Nesbitt, 1975). Another packof feral dogs ranged, over an area of about 7000 hectares in Alaska (Gipson,1982) .

As a general rule, home range appears to be smaller in more favourableh ab ita t s , especially ones with more plentiful food. The smaller range .Lnurban areas may be indicative of the increased food resources represented. byhuman f eed ing; bo.cn owner s and urban garbage are important -food sourc es fordogs.

There is little eVloence that dogs are strictly territorial, i.e., keeplngall intruders out of their range. Individual dogs superficially protect the ­borders of their range.

2.6 Population structure and turnover

The: structure and turnover of a dog population is ' de t e r mi ned by a greatnumber of different factors. Its analysis depends on vital statistics suchas sex and age ratios, natality and rearing success, and survival and.mortality rates. Since dog populations are more heterogeneous thanpopulations ,of free-living wild animals, it might be necessary to evaluatedata for separate subpopulations of owned and unowned dogs, of c onf i ne d andfree-ranging dogs, of dogs kept for different purposes, etc. The informat ionon dog demography can be related to the incidence and spread ofdensity-dependent diseases such as rabies and as a basis for predicting thestrategy and anticipated results of dog immunization and control programmes.For example, if a knowledge of annual population turnover and survival ratescan be obtained, it should be possible to calculate the percentage of thepopulation that needs to be vaccinated or eliminated in a given time perioe toreduce the probability of dog-ta-dog transmission of rabies, providing the

2.12

essential raw population data can be acquired. Techniques are also availablefor reconstructing populations to estimate recruitment and mortality ana torelate such functions to population trends and sizes (Downing, 1980).Similar data will also permit construction of predictive models that will behelpful in understanding the epizootiology of rabies and the probable effectof dog rabies immunization and control programmes. Sampling, ·s t a t i s t i ca lprocedures, derivation of estimates and interpretation of results can becomplex and assistance of demographers and biometricians should be solicited.

2.6.1 Techniques

Detailed procedures for collecting and analyzing wildlife ·( Caugh l ey ,1977; Downing, 1980) and carnivore (Dixon, 1981) population ·s t a t i s t i c s areavailable. These methods are commonly used to determine the status ofpopu l at ions by wild 1i fe b iologis t s , However, wi th few except ions, 's uchinformatio~ is lacking for dog populations.

The intensity and frequency of sampling dog popu l.a t i on s for vitalstatistics i s dependent on both the objectives of the study and the aynamicsof any given dog population. If populations are stable with little change,infrequent surveys (every 3-5 years) should be adequate to characterize theirdynamics. However, when individuals within the population are short-lived,with rapid rates of changes in reproduction, mortality and immigration, thenmore frequent data collection and analyses are needed. Of equal importancei s the question of how many data are needed to characterize populations.Tpis determination is, in turn, dependent on the number of parameters to bemeasured and the variation within these parameters. Until more demographicstudies have been made, answers to these questions are d ifficult to provide;however, the basic principles of statistical sampling app ly and appropriatestatistical assistance is recommended before data collection is initiated.

The data needed for the analysis of dog populations structure anddemography are very diverse. So are the methods to be used to collect theinformation. Any system of sampling may be subj ect to bias. .For example, .young dogs are more easily captured than older animals and the economic statusof owners is related to the probability of dog vaccination. The greater theprobability of bias and variation, the larger the sample size required.Sampling bias should be minimized when possible or at least acknowledged inreports and publications.

Major components of demographic analyses and a brief explanation of eachlS as follows:

a) Sex ratios. Data on sex ratios are needed in order to understandand interpret other vital statistics that are frequently expressedseparately for each sex (Downing, 1980). Sex ratios are also usedto calculate other statistics such as change-in-ratio indicators • . ·Variation in dog/se~ ratios may significantly influence prOductivityin the population. Sex ratios are commonly expressed as the numberof males per 100 .females (e.g., 150 males: IOU females, orl.5:l),or more conveniently as a percent 150/250 = 60% males). It shouldbe noted that the sex ratio in different samples ot sub-adult ana .adult dogs may be d'i Eferent: from the sex. ratio .a t; .0 i.r th ,

b) Age ratios and age determination~

2.13

to adult ratios are an indication of natality and productivity of thepopulations and of the pattern of mortality (Downing, 1980). Thenumber of animals in each age class is needed to calculate mortalityand survival values. Methods of age determination for variousdomestic (Habermehl, 1975) and wild species, including canids (Larsonand Taber, 1980), have been developed. But an appropriate methodfor the domestic dog is still lacking. Tooth eruption andreplacement of desiduous teeth by permanent teeth can only be usedfor animals under one year of age. Age-related tooth wear patternsare described for dogs (Haberrnehl, 1975), but they are unreliablecriteria for age determination. Tooth wear is different indifferent breeds and depends heavily on ~utrition and general livingconditions. Tooth wear is therefore very variable in owned dogs,although it might be ' more uniform in populations of free-living dogsof similar stature. Annular structures in the dentine and in thecement of tooth roots are widely used to determine the age of wildmammals (Klevezal and Kleinenberg, 1967; Grue and Jensen, 1979) andthis technique should be studied in dogs. Other methodS of agedetermination for dogs, using a combination of criteria alreadydeveloped for wild carnivores (e.g. skull suture closure, epiphysealclosure in long bones, tooth wear, relative pulp cavity width incanine teeth, eye lens weight/body weight ratios, etc.), may provefeasible and should also be investigated. Any method provenapplicable in one area may need some re-evaluation in a new studyarea. The lack of an appropriate method of age determination haslimited the analysis so far to the owned segment of the dogpopulation whose owners know their dog's year of birth. Age ratiodata are most useful when two or more data collection periods (atannual intervals, for example) are available. Changes in theseratios over time permit inferences to be made regarding changes inthe population.

c) Natality and rearing success. Measurements of natality and rearingsuccess are indicative of population health and permit inferences as ,to how much annual mortality Can be sustained before populationdeclines occur. They are also indicators of the maximum rate atwhich populations recover following control efforts or decimation(Downing, 1980). Data needed to determine natality and rearingsuccess include the number of adult females breeding, the number ofyoung born per adult female and the number of young that remain aliveto adulthood. Such data Can be collected during dog eliminationprogrammes or at dog pounds by making juvenile/adult counts and byremoving reproductive tracts and examing uteri and ovaries forembryos, placental scars and corpora lutea (Kirkpatrick, 1980).Data on the reproduction in the owned segment of a dog population canbe collected by an inquiry of owners. By questioning dog ownersinformation concerning the following should be collected:

- age structure of reproducing population

- age dependent fertility

- frequency and incidence of oestrous and gravidity

litter Slzes

- litter survival/litter mortality (diseases, predation, killing ofpuppies, etc.)

human control of canine reproduction (for population control,breeding purposes, etc.)

See Annex 2.4 for an example of a questionnaire on these prints.

cl) Mortality and survival. Dogs may be killed by disease, by traffic,by other dogs and predators, and by man by population control,disease control or the elimination of animals with undesiredpeculiarities, etc. There is a wealth of information on dogdiseases in veterinary literature (Jones and Hunt 1983). Besidesthe information gathered from dog owners and veterinarians, the datacollected by government administrations On dog control can be usedfor mortality studies. It should be borne in mind that the numberof dogs killed becomes meaningful only when this figure can berelated to dog population size. Four types of methods have beencommonly used to calculate mortality and survival; catch-efforttechniques, and life, survival and mortality tables. Detailedprocedures regarding the collection of mortality and survival dataare needed; procedures for estimating values, and examples of each,have been described in detail (Caughley, 1977; Downing, 1980;Nassar and Nosier I 1980).

An analysis of dog mortality should not only include the numberand causes of deaths (diseases, traffic casualties, etc.), but alsotheir differential importance in different segments (ownedsupervised, owned unsupervised, unowned) of a dog population.

e) Phenotype frequency. While a thorou~\ analysis of the geneticstructure of a dog population is hardly ever realizeable, it isappropriate to collect information on the frequency of oifferentbreeds, size classes, shapes, etc. These are related to ecologicalconditions, and human needs and preferences. Kennel clubs recognizeabout 200 different breeds, all of which are described in numerouspublications (e.g. American Kennel Club, 197Y). In areas withlittle or no controlled breeding it is useful to differentiatebetween different size and shapes of mongrels such as GermanShepherd,-like, Husky-like, Beagle-like, Greyhound-like dogs, etc.

f) Sources of dogs. The sources of owned dogs can be established byasking owners if their animal was purchased from an occasional orcommercial breeder, received as a gift, if it was an adopted straydog or the offspring of their own bitch, etc. (see Annex 2.4 forquestionnaire). At the same time the age at which dogs wereacquired should be investigated. The important question as towhether unowned dogs are predominantly escaped and abandoned pets orwhether they are the offspring of feral dogs needs careful assessmentof human attitudes, of individual dogs' behaviour and of reproductivesuccess of unowned dogs.

2.6.2 Observations

a) Sex ratio. The sex ratio at birth is 1 to 1. In one survey in thecentral Philippines the sex ratio of suo-adult and adult dogs wasalso found to be close to equal (Beran, 1982). But in many surveyson predominantly ownea dogs there was a preponderence of malesnoted. The ratio of .f ema l es to males on five areas was found to beas f'o l l ows ;

(Rangel et al., 1981)(West brood and AlIen, 1979)(Schnurrenberger et al., 1961(Eeck, 1973)(Daniels, 1980)

Observations on sex ratios are vulnerable to bias; they heavilydepend on the sampling procedures. Females are most often involvedin bites that get reported to health departments, i.e., they bitepassersby more than males (Beck, 1975; Beck et al., 1975; Harris etal., 1974). Males are most often involved in intra-familyaggression; males are far more commonly seen by behaviourists andtrainers for aggression problems.

b) Age structure. The mean age of populations of owned and wellsupervised dogs in the USA is approximately 4.5 years(Schnurrenberger et al., 1961; Beck, 1973, 1981a; Nassar andMasier, 1980). In these studies more than one third of the observeddogs were older than 5 years. In a similar study in Mexico Cityonly 12 per cent of the animals were found to be older than 5 years(Rangel et al., 1981). Ageing studies of pets found on the street(captured by animal control agencies) in USA cities had a mean age of2.3 years. Females were slightly older and had a slightly longerlife expectancy (Beck, 1973; 1981a).

c) Reproduction and natality. There is quite a large volume ofinformation concerning dog reproduction. Reviews on currentconcepts are published sporadically (e.g. McDonald, 1975; Jochle andAndersen, 1977; Stabenfeldt and Shi11e, 1977; Shille andStabenfe1dt, 1980). Young dogs become sexually mature at an agebetween 6 and 12 months, and some shortly after reaching adultsize. Females usually reach puberty earlier than males, smallerbreeds earlier than larger breeds. In most breeds there is an evendistribution of oestrous cycles throughout the year. Intervalsbetween oestrous cycles average between 7 and 8 months. There areconsiderable breed differences and geographic differences within thesame breed. .The intervals may be lengthened by 1 to 3 weeks by theoccurrence of pregnancy. The average length of the gestation periodis 63 days. ranging from 59 to 68 days. The mean litter size isabout 7, but there is considerable variation. Small breeds havesmaller litters than large breeds.

In contrast to the comprehensive information on the physiologyof dog reproduction is the meagre knowledge of dog breeding andreproductive success in canine populations. There is obviously verylittle breeding success among unowned dogs in urban areas in the USA(Beck, 1973; Fox et al., 1975). Feral dogs in Alabama (Scott andCausey, 1973) and in interior Alaska (Gipson, 1982) reproduce withvarying success, rearing at least some of their pups to adulthood.Reproduction among owned dogs was found to be very low in Manhattan,Kansas (Nassar and Mosier, 1980). The percentage of spayed femaledogs in this city was about 12 per cent before 1973, but hadincreased to 66 per cent by 1979.

d) Mortality. Causes of mortality include traffic accidents and a widevariety of different diseases. However, in North America, Japan andEurope the greatest number of animals die at the hands of man(Carding, 1969; Beck, 1973, 1981c; KOnig, 1979). A conservative

2.16

estimate is that many millions are killed annually after beingdelivered to animal shelters as unwanted pets.

e) Phenotypes. The urban environment appears to support a wide varietyof sizes and breeds without any selection for anyone physical orbehavioural attribute. The morphological and behavioural variationsobserved in urban areas are either a real biological phenomenonserving some adaptive function at the population level or afortuitous result of man's capricious manipulation of inherent canidvariability (Beck, 1973). But there are no meaningful statisticsavailable. Dogs observed in the rural environment of North Americaoften tend to be larger and there appears to be some selection (humanor natural) towards the darker shepherd/collie-like dog tSmith,1966; Perry and Giles, 1970; Scott and Causey, 1973; Nesbitt,1975). Owned and unowned dogs in urban and rural areas of Africaand Asia are more uniform in size and usually of lighter colour thanAmerican and European breeds.

f) Sources of dogs/dog population turnover. There ~s little evidencethat urban stray dogs in the USA successfully breed (Beck, 1973; Foxet al., 1975). Urban stray dog populations appear to becontinuously "seeded" from owned, home-bred populations throughabandonment, release or escape. Presumably, feral dogs in the ruralenvironment of North America replace their numbers, at least in part,through successful breeding (Gipson, 1982), though even in a trulyrural area in Alabama, half the free-roaming dogs captured turned outto be owned animals (Scott and Causey, 1973). Similar stud~es fromother areas with different cultural and climatic conditions are stillawaited.

The sources of owned dogs are numerous. A survey l.ll the USA of918 dogs owners at 13 animal control agencies conducted by theNational Animal Control Association reported the following sources ofdogs (Dow , 1982);

Professional breeder 47.0 per centNeighbour or friend 23.5 per centPet shop 11.7 per centAnimal shelter 0.0 per centStray 0.0 per cen t .Born in home 1.9 per centAdvertisement 9.8 per centOther 5.8 per cent

Al though this particular survey found no one who obtained their dogfrom a shelter, shelters do supply animals, though a review of thenumbers indicates that it is rarely more than 6 per cent of the totalpopula t ion. The figure quoted for ' pet shops 'is cons is tent wi thtrade estimates. This survey also found that the more an an~ma1

costs, the longer it remained in the home, hence the bias towardsbreeders (Dow, 1982).

A study of the owned dog population in Manhattan, Kansas (Nassarand l'los ier; 1980) revealed tha t the age d is tribut ion and thus thepopulation size was stable. ~lenonly age-dependent birth andsurvival were considered, the population would be expected to declinerapidly, but a high net rate of immigration of. young dogs fromoutside the city was responsible for maintaining a stable population.

2.17

The population turnover can be exacerbated by animal controlactivities. Surveys were conducted in 1975 along the US/Mexicoborder tabulating the extensive questionnaire data that was generatedby the local animal contro l agencies. . In general, the mean age ofhousehold dogs in cities that had aggressive dog capture programmeswas lower than comparable areas with little capturing activities(CDC, 1976). The dog population in the US appears to be decreasingboth in numbers and biomass ( sma l ler breeds are again becoming morecommon) (American Kennel Club, 1975; Wilbur, 1976). This reductionmay be due to a decrease in fecund ity as well as to increasedmortality. The actual fecundity and mortality of dogs (as opposedto sales and survey data) are not known.

2.7 Feeding habits

Studies on feeding habits of dogs overlap with habitat stUdies. Spatialand temporal distribution, predictability and availability of food areproperties of the habitat. But investigations on dog f eeding focus also onnutritional requirements, on food quality, on feeding strategies, on resourcepartitioning with other species, on food chains and on energy flow. Foodquality, distribution and availability are heavily dependent on culturalpractices and on human att itudes towards dogs. Dog feeding habits havepublic health implications (hygiene, spread of pa r a s i t i c diseases, etc.).They can be of ecological importance throu gh garbage removal in one habitat,and through predation on wildlife in another situation.

2.7.1 Techniques

Nutritional requirement of dogs and nutrient con t en t o f foods ne ed to beinvestigated by the methods of animal physiology. These will not be dealtwith here. But in order to understand the feeding strategies of dogs someinformation on these subjects can be gained by c onsulting respective ·literature (Ferrando, 1973; Gaines Dog Research Genter, 1974).

Questionnaire s ur vey s should reveal information on whether owned dogs arefed regularly or not, on the proportion of f oo d dogs have to find on theirown, on the feeding of other people's do gs and on the feeding of unowned dogs(see Annexes 2.4 and 2.5).

Field observations may serve to record th e uptake of d~fferent types offood items and their distribution. Thereby it should also be noted how muchfood dogs receive through regular feeding by man, through occasional handouts,through scavenging in garbage and waste or throu gh predation on rOdents, game,domestic animals, etc. Field investigations need the same training andequipment (binoculars, night viewing devices) as used for behavioural studies(see Lehner, 1979, and Section 2.9.1).

Tagging of food items with markers excreted with the faeces should giveindications on the exploitation of resources (see also Section 2.4.1).

Information on the diversity and the importance of different food itemscan be gained by post mortem examination of dogs k illed by traffic or duringpopulation control operations. The stomach content of fr e sh l y killed dogsshould be examined within 24 hours. If this is not possible, the unopenedstomachs or the weighed contents should be preserved in a 5 per cent to 10 percent solution of formalin. The analytica l procecures for stomach contentscomprise several steps (described in detail by; Korschgen, i980). Theidentification and classification of food items needs training and

2.18

experience. Collections of reference preparations of hair, feathers,arthropods, seeds, etc. may be needed. Some information may also be gainedby analyzing dog seats in a similar way.

It is important to analyze data on nutrition relative to season and to thesample se~nents (unowned, unowned unsupervised, owned supervised) of a dogpopulation.

2.7.2 Observations

In urban USA dogs find food at home, eat garbage, and receive handouts(Beck, 1973; 1975) . The frequent occurrence of unsupervised dogs in alleyswhere there ar e garbage containers and in parks at evening indicate that theyeasily learn to find food in the urban environment. Dogs shift within theirhome range and vary their feeding activity ~ccording to varying distributionof food (Beck, 1973; Daniels, 1980). Water is available in gutters andsidewa1k puddles filled by r ain, car washing, leaking fire hydrants and airconditioning units, and from people putting out water for their pet dogs andcats and even for stray dogs. Urban fountains, streams and lakes are alsoused . In North American cities sick animals a.e often seen, but starvingstray dogs are only ve.y seldom observed. Although t here a.e no studies ofthe quantity and quality of the garbage available to urban stray dogs, itappear~ adequate to sustain the population.

While the availability o f garbage may be similar in many cltles in otherparts of the world, the sources and abundance of water depend more heavily onclimatic and cultural conditions.

In a publication on dog ecology in the central Philippines (Beran, 1982)it is stated that owned dogs scavenged garbage, received leftover human foodand frequently ingested human faeces. A survey in rural Tunisia (unpublisheddata) revealed that only a small proportion of the owned dogs were chainea upall the time. Only these animals were fed by their owners. The dogspermitted partial or total freedom had to look for food, consisting mainly ofgarbage, rodents and insects.

Feral dogs in rural USA seem to depend very heavily on litter and garbage,and also on carrion, small mammals, insects, fruits and some green vegetation(Scott and Gausey, 1973; Nesbitt, 1975; Gipson, 1982).

In North America and Europe unowned and unsupervised owned dogs areconsidered to be a major enemy of wildlife and small livestock (Barick, 1969;Fe1dman and Carding, 1973; Caras, 1973, 1974), although some investigationsdo not confirm this opinion (Progu1ske and Baskett, 1958; Sweeney et al.,1971; Nesbit, 1975). There is no doubt that the introduction of dogs onpreviously vertebrate-predator free islands had disastrous effects on theground-dwelling wildlife (e.g. on the Galapagos Islands, see Thoruton, 1971;Lewin, 1978).

Urban dogs in the USA have been observed chasing cats, squirrels and deer,although a capture appears very rare (Fox et al., 1975). Predation isprobably not a significant source of food for city dogs. Unsupervised ruraldogs may rely more heavily on both wild game and small livestock, althoughmost reports of livestock kills do not report eat ing of the animals killed(Smith, 1966; Perry and Gi1es, 1970). The same is reported of dogs killingzoo animals, even when there was ample time for feeding. On the other handtruly feral dogs in Alabama returned toa carcass until it was consumed (Scottand Causey , 1973). Sixty-five chases of white-tailed deer by hunting dogsover distances of 0.3 to 22 km lasted 3 to 155 minutes, and resulted in not as ingle catcll (Sweeney et aI, 1971).

2.8 Activity patterns

The behaviour of dogs varies. on a daily cycle. The daily pattern ofdifferent activities (behaviour) of a dog is influenced by internal andexternal factors. Internal factors causing variation are age, sex, phase ofbreeding cycle, health, etc. External factors are season of the year,weather conditions, other dogs, temporal pattern of food ava~lability,

constraints imposed by owners, etc. Activity studies usually rely on therecording of a limited number of rather unprecisely defined activities(behaviour). Some knowledge of tbe activity pattern of dogs in a given areais essential for investigations of dog abundance, for more detailedbehavioural studies, and for planning and executing control and vaccinationc ampa i gn s ,

2.8.1 Techniques

The analysis of dog activity cannot really be separated from otherbehavioural studies nor from inv estigations on home ranges and movements.The activities of urban dogs and of owne d dogs in rural areas can be followedby direct observation with the aid of binoculars and night-viewing devices ifneeded (Beck, 1973; Fox et al., 1975; Daniels, 19(0). The behaviour ofindividual animals may be recorded continuously or at regular intervals. Adlibitum sampling may also provide information. The different samplingtechniques are described best by Lehner (1979). Less precise samplingtech niq ues should not be appl ied. The method 0 f 0 bservat ion (d iree t or bytelemetry) and the experience of the observer limit the number of differentbehaviour patterns which can be recorded. These have to be defined and dataforms have to be prepared before the actual field study is initiated. Theclassification of behaviour might be as simple as resting as opposed to beingactive or moving, or it might segregate an animal's activities in numerousgestures, behavioural acts and their component parts. Scott and Fuller(1965) suggested a scheme by classifying behaviour as ingestive,investigative, shelter-seeking, eliminative (excretory), sexual, epimeletic(giving care), et~epimeletic (soliciting care), allelominetic (imitating,etc.), and agonistic. This system is also recommended by Westbrook and ALIen(1979) .f or the study of urban dogs. The maj ority of Scott 1 s behaviourcategories are functional units. Therefore the function of a particularobserved behaviour has to be determined before it can be classified in Scott'ssystem. Instead of using this system of behaviour classification it might beeasier to apply purely descriptive terms, such as sleeping, resting, walking,­running, defecating, urinating, etc. For studies on dog activity it isstrongly recommended that the advice of field ethologists should be sought.Good basic information on methodologies, statistics and pitfalls is given LnLehner I s "Handbook of ethological meth cd s " (Lehner , 1979).

2.8.2 Observations

Several studies on the activity of dogs in North American cities indicatethat daily cycles may vary according to environmental conditions. InBaltimore, Maryland (Beck, 1973), in St. Louis, Missouri (Fox et al., 1975),and in Newark, New Jersey (Daniels, 1980), the observed number of free-roamingdogs peaked in early morning and in late afternoon hours. In Newark thepattern changed in winter, the highest number of dogs being observed in thelate morning (Daniels, 1980). Westbrook and Al1en (1979) report that inSacremento, California, the greatest activity of free-roaming dogs occurredduring the midday period. In the same area the number of observed dogsincreased during the weekends. A pack of 3 stray dogs in St. Louis,Missouri, was predominantly nocturnal (Fox et al., 1':175). The number of

2.20

freeroaming dogs counted in the streets of a city depends on the activitycycles of unowned dogs and on the human cycle of temporal release of petdogs. For North American cities the following generalization roay hold true~

urban stray dogs are active in the early mornings,late afternoons andsporadically throughout the night. Owned pets appear on the streets wellafter sunrise, which is when the two populations interact. Strays are oftenactive, later during winter months than summer ones: in addition, extremeheat in general lessens the activity.

Feral dogs in rural areas of North America appear to be more nocturnal.However, pack movements occurred at all times of day and night in a study inIllinois (Nesbitt, 1975). Feral dogs in Alabama showed an increase indaytime activity during the cool season (Scott and Causey, 1973).

Beck (1973) classified the behaviour of free ranging dogs in Baltimore.Maryland, ~s resting (19.2%), moving (68.0%), feeding (11%), socializing(0.9%). and mating (0.9%)~ Of 65 dog groups observed in Newark. New Jersey,9.2% were engaged in foraging, 27.7% in walking and standing ana 33.8 per centwere lying down (Daniels, 1980). Westbrook and AlIen (1979) attributed theactivities observed in dogs of Sacramento, California, to 36.0% investigation,20.2% elimination, 17.4% social interaction, 8.9% shelter seeking, . 5.5%ingestion, 5.5% self-grooming, 3.5% agonistic behaviour and 3% sexualbehaviour.

2.9 Social organi~ation of dog populations

Dogs are gregarious. They aggregrate in groups that are not random, butindicative of social organi~ation. Depending on the cultural setting, manrestricts contact between the individual animals of a varying proportion of adog population.

The social behaviour of dogs in the context of physical contact with otherindividuals, or groups of dogs within the population, as weli as theircontacts with humans, has important implications in connexion with thetransmission of rabies and other density-dependent diseases. Such behaviouralso becomes important when dogs are in contact with other pet species inurban environments, with livestock on the fringes of urban areas, and withwild carnivores, especially wild canids and feral dogs, along the urban-ruralinterface or in wholly rural habitats.

A catalogue of topics to be studied In the context of social behaviourshould include the following:

the frequency of occurrence of single dogs and social groups Inrelation to season of the year

age, sex) breed and phenotype composition of social groups

the stability (i.e., persistence over time) of dog groups

, beh av i our displayed between groups of dogs

the percentage of time single dogs spend within groups of two or moredogs

the probability of encountering another dog at either home or atvarious distances from home

the frequency of dog encounters with familiar or "known" dogs andwith strange dogs, and behavioural responses during encounters(grouping or avoidance)

behavioural responses to sick (rabid) dogs.

2.9.1 Techniques

Some information on dog social organization may be gained by simplerecording of group size and composition in relation to time and area. Anapplicable definition of the term "group" is important for this kind of datacollection. A "group" is a set of dogs remaining together temporarily orpermanently while interacting with one another to a greater degree than withother dogs. Daniels (1980) used a more operational definition for actualrecording of dog group sizes in a field study defining a group as the numberof dogs that remained together for at least one minute of observation and didnot show any agonism or avoidance .

Most of the epidemiologically importaat questions about spatial relationsand frequency of interactions among the individuals of a dog population needto be solved by labour intensive field operations. For this purpose, themajority of all dogs of a study area should be knowr. individually. Every dogin the study should be given a short des ignation (name, number, letter orother). For identification he has to be photographed, and sex, size, shapeor breed, age (pup, juvenile, subadult, adult), colour, and otherdistinguishing lnarks have to be recorded. By this way urb~n dogs and ownedrural dogs can be individually recognized (Beck, 1973; Fox et al., 1975;Daniels, 1980). The behaviour and the interactions of the dogs in the studyarea can then be recorded on previously prepared data sheets using thesampling methods of field ethology (se.e Lehner, 1979).

2.9.2 Observations

Several publications surr~arize what is known about dog social behaviourand also provide knowledge concerning both inrerspecific and intraspecificrelationships (Fox, 1965; Sc o t t and Fuller, 1965; Scott, 1':f67; Fox, 1971;Fox, 1975; Bekoff, 1977; Fox, 1978; and others). Most of thesepublications are primarily descriptive, or they focus on ontogenetic orevolutionary problems. Only a few studies examine the quantitative aspectsso important for epidemiology. Morning surveys in Baltimore, Maryland, on aquarter square mile study plot revealed the following group sizes (N=2~

Female pairs were never observed; groups rarely had more than one adultfemale. Similar observations were made in Newark, New Jersey (Daniels,1980). In both studies unowned dogs and loose pets did interact, though thegroups appeared to be transient. Loose pets interacted among themselves, butagain for only short periods of time, often encouraged by some desirableresource like garbage or a novel object.

Groups of unowned dogs in rural areas of North America are much morestable. Packs of 2 to 5 dogs were observed in Alabama (Scott and Causey,1973). Packs of usually 5 to 6 dogs are reported for a wildlife refuge inIllinois (Nesbitt, 1975). In Alaska the size of a pack of feral dogs rangedfrom 3 to 11 (Gipson, 1982). In these studies individual dogs stayed for upto several years with the observed packs, and pack size and compositionremained un changed for up to 6 months. The activities of a trio of unowneddogs having a similar coherence in St. Louis, Missouri, was described by Foxet al (1975).

2.10 Dog functions in human societ ies

The sizes of different segments (owned, unowned) of a dog populationdepend very heavily on the proportion of the human population keeping dogs,tolerating dogs, or rejecting dogs in their neighbourhood. Dogs can be keptas pets and companions, for hunting, as guard dogs, draught animals, for foodor for commercial buying and selling, etc. For certain tasks special breedsare raised. Besides the duties dogs are kept for, they may also fulfillbeneficiary functions in other ways. Dogs can also be rejected because theyare unclean (in a religious or a hygienic sense), because they bite, orbecause they are disease vectors, pests or nuisances. There are qualitativeand quantitative differences in what people think the functions of dogs areand what dogs really do. In different cultures dogs are regarded assupernatural or related to supernatural powers, either as divine beings or as-ev i I spirits. Dogs bear human names, specific dog names or no name saccording to local tradition. Functions and values attributed to dogs andother aspects of the cultural and ecological setting determine the conditionsin which dogs are kept, how much they are cared f or and the degree ofsupervision. Popular beliefs c onc er n i ng dogs al so influence the acceptanceof governmental regulations aud disease control measures.

2.10.1 Techniques

The analysis of dog funct ions in human societies requires amultidisciplinary approach. Anthropological or sociological questionnairesurveys need complementary behavioural field studies. Examples ofquestionnaires are given in Annexes 2.4 and 2.5. These questionnaires haveto be adapted to local conditions. The questions have to be formulated sothat the respondents are not tempted to tell what they think the interviewerswould like to hear. The difficulty in getting correct information isindicated by the following example. If the possession of dogs is subject totax, respondents may be reluctant to indicate the correct number of dogs theyown. Under these circumstances the question: "How many dogs do you own?"might be replaced by "How many dogs do you feed?" The second question againdoes not give any information on dog ownerShip ~n regions where owned dogshave to find food of their own. Observational field studies may have toreplace questioning under these conditions.

For the des ign of ques t ionnaires the advice 0 f anth ropo logis t s orsociologists experienced in field surveys should be solicited. Informationon field survey methods can also be found in the" Interviewer's Manual"

published by the Institute for Social Research in Ann Arbor (InterviewersManual, 1969) and in Sellitz et 801. (1976). . Questionnaires which could beused for collecting information on attitudes concerning dogs and dog ownershipin industrial societie~ were published by Westbrook and AlIen (1979).

The amount of time owned dogs are supervised, or are fulfilling certainduties (e.g., guarding), the proportion of food they receive from their owner,from other people and find on their own, and related questions need to beinvestigated by observational data sampling methods mentioned in Sections2.5.1,2.7.1,2.8.1 and 2.9.1.

2.10.2 Observations

Observations on dog functions in human societies are relatively abundantin the anthropological and ethnographical literature, but most accountsconcerning the cultural and economic values attributed to dogs are relativelyshort and incomplete. A few more detailed accounts concern dingos inAustralia (Meggitt, 1965), dogs in Polynesia (Luomala, 1960), and in Alaska(Nelson, 1969, 1973). A comprehensive review of publications treatingcultural aspects of dog keeping in Africa was publ~shed by Frank (1965).Papers on psychologic aspects of pet ownership and on attitudes toward pets inurban societies of industrialized nations (e.g. Westbrook and Allen, 1979;Fogle, 1981) al:e becoming quite numerous.

Dogs fulfill a variety of cultural and economic functions. Theethnogra~lical literature aboundS with remarks that dogs are also kept at acertain place and that they are used for such and such. frank (1965) citescl os e to 600 pub 1icat ions in h er rev iew 0 f the role 0 f th e dog in Africancultures.

Dogs may constantly clean up and permanently guard a settlement, but otherduties (e.g., hunting, pulling veh i,c les, e.t c , ) may be performed only duringrelatively short periods. The reason for the association of people with dogsis frequently not so obvious (see Meggitt, 1965). Their importance andefficiency for hunting is often overstated. Dogs or dingos are obviously notof great help to hunting parties of Australian aborigines (Meggitt, 1965).South African bushmen use dogs only to hunt certain game species; but tbeowners of well trained packs are more successful than those without (Washburnand Lancaster, 1968; Yellen and Lee, 1976). Hunting dogs are highlyesteemed in most cultures, even by people who do not primarily depend on game­as a resource.

In some areas of Eurasia and North America dogs are used to carry goodsand to pull sledges, travois or carts. This cultural trait is becomingespecially widespread in the northern circumpolar region (Graburn and Stiong,1973). The high dependence of man on dog teams as means of transportationevoked especially detailed consideration in accounts of arctic cultures (e.g.,Gubser, 1965; Uswalt, 1967; Balikci, 1970; Nelson. 1973). It has to bementioned that dog traction is relatively you~g in the arctic and that dogswere also used Eor other purposes, e.g., for hunting and as a meat source(Lan t is, 198()) .

Despite the obvious importance of dogs for herding cattle, sheep and goatsover large areas DE the old world, very little attention has been paid todog-pastoralist relationships. A large proportion of the older breeds 1nEurasia and Africa were raised to guard livestock, but other guardingfunctions in premises and plantations have not yet been the focus ofethnographical studies.

Dogs are eaten by many tribes and in many cultures on all continents.Frank (1965) describes the tribal distribution of ritual killing and eating ofdogs in Africa. She suspects that dog eating is orginally a West Africanagricultural trait, but she gives no explanation for this association. Dogsare castrated by a few African tribes for the purpose of making them fatterfor eating (Frank, 1965). The complicated relations in Polynesia betweendogs as food, as gifts and offerings and as other items of value are describedby Luomala (1960).

The fact that dogs eat refuse and human faeces is recognized and theircleaning function is often esteemed. In some places they are even left toclean and guard babies and small children (Frank, 1965).

More often than is expressed in the literature, dogs are kept as pets.The pet function is not so easy to define. In many languages (Spanish,French, German, etc.) a precise translation of the English term pet does notexist. Pets in industrialized societies have been reported to serve thefollowing functions~

A pet is a companion

something to care forsomething to touchsomething to keep one busya focus of attentiona reason for exercisesomething to make one feel safer.

It seems probable that pet dogs help to offset some of the pathologicaleffects of social isolation (Katcher and Friedmann, 1980). The psychologicalimportance of owning a pet becomes well documented for industrializedsocieties (Fogle, 1981). To own a pet as a companion might also be moreimportant in hunter-gatherer and simple peasant societies than recognized sofar (Luomala, 1960; Frank, 1965; Meggitt, 1965). From Frank's (1965)monograph on the role of dogs in African cultures it becomes clear that theattitudes toward dogs vary from tribe to tribe. Dogs are despised andmistreated by some African tribes. In others the dog is a venerated culturehero as the bringer of fire or grain. In a few areas it is an offence tokill a dog. But quite often the way they are treated is not in accordancewith the merits of their mythical ancestors. Some muslim people believe thatdjinns (ghosts) may take the shape of a dog (Zbinden, 1953). In these areasunknown dogs are treated with respect or contact with them is avoided. Incomplex societies the attitude toward dogs may be different in differentsocial strata and may vary according to professional occupation, subsistencelevel and economic status (Franti et al., 1974; Rangel et al., 1981).

Ideas about ownership and responsibilities are also quite variable. Inwestern societies the law and public attitude gives people the right to owndogs, but also the obligation to care for them. Care of an animal has toinclude, but must not be limited to, adequate shelter and wholesome food andwater. The owner is responsible for ensuring that his dogs do not damagepublic or private property other than his own, that they do not defecate onpublic or private property other than his own, that they do not causeunsanitary, dangerous or offensive conditions, they they do not causedisturbance by excessive barking, that they do not chase vehicles, or molest,attack or interfere with persons or other domestic animals.

2.25

In other cultures the o~ligations put on dog owners are often considerablyless restrictive. But ownership and responsibilitie~ may ~ti11 be regulatedby more or less complicated rules. In the Tlingit Indian tribe of north westNorth America dog ownership is an individual matter, but responsibility iscontrolled by the clan. If a dog bites a person, the owner of the dog has tocompensate only if the injured person belongs to another clan (Oberg, 1934).In another north west American tribe, the Bella Coola Indians, the dog namesare clan property, and no two canines may bear the same one at the same time(McIlwraith, 1948).

To terminate this brief account of dog functions in human societies, itshould be stressed that a systematic and comprehensive review does note x i s to love s t iga t ion is s ti 11 required i nt o the e pidemio logica lly importantquestions concerning the number of dogs kept, the treatment and care of dogs,and the amount of freedom permitted in relation to dog utility, folklore,beliefs, economy and ecology.

2.11 Dog diseases and public health

As in all otller vertebrates, dogs harbour a great variety ofmacroparasites, microorganisms and viruses. Some of the more pathogenic onesmay be important factors of mortality in dog populations.A good proportionof the infectious agents disseminated among and carried by dogs are alsoharmful for man. Rabies and hydatidosis are among the most importantdiseases transmitted from dogs to man. Dog bite accidents are also ofconsiderable importance for man. The amount of dog faeces deposited onpublic or private property becomes a hygiene problem in many cities. On theother hand there are the beneficial effects of garbage and waste removalthrough dogs. The psychological importance of owning pet dogs has only beenrecognized quite recently.

2.11.1 Methods

The occurrence of dog diseases and their demographic importance have to bestudied using the methods of veterinary parasitology, microbiology, pathologyand epidemiology. The techniques for rabies diagnosis and surveillance aredescribed in chapter 5 of these guidelines, those for hydatidosis in theFAO/WHO Guidelines for Surveillance, Prevention and Control ofEchinococcosis/Hydatidosis (1981). For many other dog diseases thediagnostic features are described in handbooks and numerous specialpublications. The diagnosis of dog diseases should be made by trainedpathologists, parasitologists and microbiologists. Administrators involvedin disease and dog control should be familiar with medical statistics and withsurveillance procedures. To those not familiar with epidemiologicaldefinitions and calculations the consultation of relevant literature (e.g.,Halpin, 1975; Schwabe et al., 1977) is highly recommended.

The frequency and the implications of dog bites have to be investigated byquestionnaire surveys. Informat~on on some aspects of dog bite accidents maybe gathered at public health centres for those bites for which medicalconsultation is requested. Reporting forms should include questions aboutdate and time of the accident, age and sex of the person bitten, part of thebody bitten, type of activity in which the victim was engaged, place ofoccurrence of the bite accident, type and breed of dog, and whether the bitingdog and his owner are known to the victim. Valuable informatl.on on thedesign of questionnaires can be found in Payne (1951), Oppenheim (1966) andother s ,

2.26

No method has been proved so far for the estimation of the percentage ofavailable garbage and waste removed by dogs. Such studies should beundertaken in connexion with the habitat analysis described in Section 2.2 ofthis chapter.

Consultation of the relevant literature (Levinson, 1972, Friedmann et al.,1980) is recommended for those wishing to learn about the types of social andepidemiological investigations needed for the study of the potential healthvalue of pets.

2.11.2 Observations

There is a wealth of information in veterinary literature about theoccurrence and age, sex and breed dependent frequency of different dogdiseases (e.g. in Jones and Hunt, 1983). Unfortunately this knowledge islargely limited to the well-cared-for dogs owned by city-dwellers. Verylittle is known about the mortality factors of unowned dogs or of owned dogs1U rural areas of Africa, Asia and Latin-America.

A review of the epidemiological knowledge on rabies is given inChapter 1. Information on hydatidosis epidemiology is summarized in theFAO/UNEP/WHO Guidelines for Surveillance, Prevention and Control ofEchinococcosis/Hydatidosis. Rabies and hydatidosis are only two of the mostimportant of more than 100 zoonotic diseases transmitted from dog to man(Hull, 1963; Van der Hoeden, 1964; Carding, 1969; and others). Dogs arealso involved in the epidemiology of Rocky Mountain spotted fever in SouthAmerica, Chagas disease, visceral leishmaniasis, diphyllobothriasis,trichinosis, dirofilariasis, strongyloidiasis, larva migrans of Toxocara can~s

and of Ancylostoma brasiliense (Hubbard et al., 1975; Acha and Szyfres, 1980).

Very little is known about the recognition of different specific dogdiseases and zoonoses in different cultures. The anthropological literaturegives no indication of whether dogs with signs of disease are cared about orif they are confined or killed. Cultural practices greatly influence theoccurrence of zoonotic diseases, as demonstrated by Lantis (1980) in the caseof echinococcosis and Haskan EskilUOS.

Increasing recognition is given to the importance of dog bites.Epidemiological features of the occurrence of dog bites are described forseveral areas, mostly urban or suburban (Berzon et al., 1972; Harris et al.1974; Beck et al., 1975; Lockwood and Beck, 1975; Hervey, 1977; Moore etal., 1977; Winkler, 1977; Marr et al., 1979; Nixon et al., 1980; Beck,1981c). The mean annual animal bite rate per 100 000 total population variedbetween 20 in South Carolina and 927 in Arizona in a survey conducted in theUSA by Moore et al. (1977). Robinson (1976) puts it at 500 per 100 000 inLiverpool (UK), and Nixon et al. (1980) recorded a mean annual dog attack rateof 184 per 100 000 total population in Canberra, Australia. Many of theauthors point out that rabies is not the main disease transmitted by dog bites- tetanus, pasteurellosis and other diseases are also transmitted in thisway. Bite wounds are vulnerable to a great variety of infections. Dogbites are certainly of greater importance in developing countries thanofficially recognized. This is suggested by th~ great discrepancy betweenthe high number of people receiving post-exposure treatment against rabies andthe low figure of actually diagnosed rabies cases in humans and in dogs.

The educational value of pets has long been recognized (Levinson, 1972;Fox, 1975b, 1979; Frucht, 1980). Pet dogs may also be of value for thehealth of their owners (Katcher and Friedmann, 1980). There is growingevidence that companion animals have potential health benefits. Lonelinessper se is bad for health; people who are alone have increased rates for mostdiseases and injuries. It seems likely that pet dogs help offset some of thepathological effects of social isolation. Animal owners have been shown tohave a higher rate of survival from coronary heart disease - an effectindependent of other social support systems. The relationship between animalownership and survival one year after myocardial infarction was as follows(Friedmann et al. 1980):

There is an evergrowing tielct of pet-facilitated therapy utili~iug a widevariety of animals for many special populations of people; elderly, aut1stic,depressed and imprisoned. Dogs often play a leading role in this work(Corson et al., 1975; Beck, 1981b; Curtis, 1981).

The human/companion animal bond, especially with the dog. 1S a real one,that affects the health of both parties. Good animal management comprisesthe same factors that enable animals to fit well into human society (Beck.1980b, 1981a). It is possible for people . and animals to live together inhealth and happiness.

ESTIMATING THE NUMBER OF FREE-ROAMING DOGS

INTRODUCTION

Be consistent in your observations. Use the same methods and time of dayfor your observations and maintain careful records .. Make observations duringthe time of maximum activity for the dogs in the area. As a general rule,free -roaming dogs are best observed in the early mornings, a time of maximumdog activity, less human activity and good visibility. Take advantage oflocal areas that are best for observation; e.g. specific market streets, dumpsites and known pathways. Maps of the study areas are very useful; preparework sheets to aid the user.

I. METHODS FOR ESTIMATING NUMBERS

Several methods require nothing more than being able to observe andphotograph each individual animal and plot its location on a map of thearea. Doing both at the same time permits estimating the population usingtwo different methods. Once an estimate is developed for a specific studyarea of known size, the population can be assumed to be the same for similarareas. Several different study areas can be samples when necessary.

PHOTOGRAPHIC "RECAPTURE" METHOD

It is not actually n~cessary to capture and mark animals if they can beindividually distinguishable so as to determine recaptures. Dogs are sovariable that they lend themselves to this sampling approach. It isdifficult to remember every dog observed, but photographing every individualdog while surveying the same area, in the same way on two or more occas~ons,

will generate the data that can use the recapture proportion~

11. METHODS FOR ESTIMATING NUMBERS WITH REMOVAL

In many areas, intensive dog capture programmes are underway. Theseprogrammes often keep records of the number of animals captured and removedfrom the population. These records can be used to estimate the animalspresent in the population.

REMOVAL ~ffiTHOD ESTIMATE

If the removal of dogs lowers the population, it is theoretically possibleto calculate the decline to estimate the total number of animals that could be"theoretically" removed. Plotting the numbers removed each day against theaccumulated total removed to date could be extended to the point where,theoretically, all animals are removed, i.e. the total population that waspresent in the area.

In reality, rarely are enough animals removed to make such a plot veryuseful. However, grouping the numbers removed (e.g. totals removed per truckor per day) over a period of time can be treated as two captures and analysedusing the following formula:

Yl ~ the number removed the first time;Y2 the number removed the second time;N the estimate of the population.

CHANGE IN RATIO

Significant removal of animals during a dog catching campaign, should alsoinfluence the number of dogs observed, e.g. dogs observed at a dump sitebetween 6-7 a.m. or their tracks (after old tracks are swept clean).

The logic is simple and easy to use:

Cl C1-C2 C2 therefore: NI R(CI -C2) and- '" ----

R(CZ)/ (Cl -CZ

)NI R NZ NZ

where: Cl the number of animals counted before removal;

Cz = the number of animals counted after the removal;

R the number of animals removed during the study; and

NI and NZ = the numbers of animals that were in the populationbefore and after removal, respectively.

Example: An average of 14 dogs were observed daily around a dump before aweek of intensive dog catching; then the average dropped to 9 dogs per day.During the study period, 63 dogs were removed from the area. The populationbefore and after the capture programme can be calculated as follows:

14(63)/59(63)/5

176 and113

This method can be implemented periodically to monitor the effectivenessof control programmes and detect changes in the population.

This questionnaire IS composed ot 2 parts.

Part ~ asks for household information, about the number of dogs kept ill thehousehold and about recent changes in dog numbers.

Part B is a form to collect information on indiVIdual dogs.

The questionnaire is too long in the present form. Edcn part shoulct bereduced to two pages (front anJ back of one sheet). The quest ions notserving the purpose of the study should be eliminated. Important questIonsessential for every dog population study are markeJ WIth an asterIsk (*).~any questions need to be reformulated in order to fit local conditions.Those which definitely need adaptation are marked with an alpha (a). Thereare also questions which may not be asked under certain social or politicalcircumstances (marked with b).

Be aware that the answers to the questionnaire do not tell the wholestory. You will only get some information on the sub-population of dogsowned by Individuals or households. The questionnaires do not replace dogcensus, population turnover studies, home range studies, or investigations ondog habi t a t and on C ommun i t y-rowned and unowned dogs.

The quality of a survey further depends on the correct selection ofrespondents 80d on the abilities of the interviewers to get the correctanswers.
