A concise and accessible guide to the various conditions which affect the process of reproduction in dogs and bitches. The book considers all aspects of the physiology, anatomy and endocrinology of the male and female reproductive system, followed by a discussion of mating, pregnancy and parturition. Later chapters describe problems such as anatomical abnormalities, abnormal physiology and endocrinology, intersexuality, infertility, contraception and surgical procedures. Building on content first published in Allens Fertility and Obstetrics in the Dog (Blackwell, 1998) this book is fully revised and updated, with substantial new material designed to give practical guidance to the professional breeder as well as the vet.
