BOOK REVIEW Working Dogs - Training for Sheep and Cattle, Colin Seis, Butterworth-Heinemann Australia, Port Melbourne Victoria, 1995, 136 pages, $29.95, ISBN 075068920X

olin Seis has made a study of working dogs in Australia and has recorded his knowledge and experience in C 'Working Dogs'. The book opens with a discussion of the origin and history of Australian working dogs referring in particular to the Border Collie, Australian Cattle Dog and Australian Kelpie.

Details of the bench standards of each breed are then presented. Advice is given on selection for various types of work and the initial training necessary for basic obedience and to develop the dog for farm work. Some detail is presented to promote the understanding of working sheep and cattle in the field and in stockyards. Advice is given for the additional skills some owners seek in training for dog trails.

The book covers the training of the dog and advises on the care of dogs in general and behavioural problems and their eradication in particular. The author maintains that the wayward dog can easily be prevented from chasing cars and killing fowls!

The final section, 'Diseases of the working dog' presents a condensed study of canine medicine in 15 pages. This covers internal parasite infestations including details of treatment, external parasites including fleas and mites and viral infections. A section 'Zoonoses - the human health risk from dog worms' gives details of this problem. Fortunately the basic advice to wash hands after handling dogs is included.

The book is simple, comprehensive and clearly organised with many headings diving the text. It is well illustrat- ed with photographs and drawings with simple diagrams of the life cycle of several internal and external parasites.

Veterinarians would be pleased that the author has suggested that owners consult with them particularly for vac- cinations on an annual basis and for parasitic infestations not responding to his recommendations.

The author has many years of experience in breeding and training working dogs and he has managed to convey this knowledge in the book in an easily understood form. It is an appropriate member of the series of 'Practical farm- ing' and can be well recommended to farmers involved with working dogs.
