Summary:

Deafness in pets is a very common problem and is increasingly being presented to veterinarians as owners and breeders become more aware and concerned about such issues. This book provides complete coverage of the subject, describing the anatomy and physiology of the auditory system; types of deafness such as partial, hereditary and later onset deafness; testing for deafness and methods of management. Living with a deaf pet also presents its own challenges; through sections on behaviour and hand signal training, this book provides a practical overview of home-based training and management.

A valuable resource for any veterinarian, this book delivers a compilation of all the relevant information within the field. It is also of interest to students of veterinary studies, dog and cat breeders and researchers into deafness. Book jacket.
