The book is divided into three parts. Part I gives an overview of the physiology and behavior of horses and how to keep them healthy. It covers routine health care, first aid, and when to call a vet. The large illustrations of the skeleton and the nervous, circulatory and urogenital systems are particularly useful because they are superimposed on the photograph of an actual horse.

The second part is called an "Anatomical Index of Diseases". In chart format with headings of Disease, Symptoms, Cause and Treatment, it covers various disease conditions. Taking after the Illustrated Veterinary Encyclopedia for Horsemen, this book groups diseases according to the part of the horse affected. It's not as detailed as the former, but the pictures are much better. Like the first section, Part II is generously illustrated with excellent photographs.

Part III is more like a dictionary or encyclopedia with additional information on the topics covered in the first two parts. Unlike the first two sections, it is set up for reference rather than browsing. If you are looking for an easy-to-understand but comprehensive veterinary reference book, The Complete Equine Veterinary Manual would be a good choice.
