Complete Equine Veterinary Manual: A Comprehensive Guide to Horse Health 
Readers will find detailed assessments of the cause, symptoms and treatment of every known equine disease, enabling them to access relevant information as quickly as possible. It also offers two cross-referenced routes for finding the necessary guidance: 1) via an index of known equine diseases throughout the world, and 2) an alphabetical encyclopedia of specific diseases. Full-color photographs accompanying various maladies aid in identifying specific conditions.
Including the latest research from all over the world, this book is a must-have for veterinary surgeons and students, and the perfect addition to the bookshelves of amateur and professional horse owners alike.

Reviews
It does not go into any great detail but explains most things that may happen to a horse.
It has lots of photos and this is great when you are trying to explain to students what each illness ect. is and what it looks like.
Overall a good book for any horse riders collection
The book itself is in several sections, which makes it a little repetitive. The main portion of the book is dedicated to categorising various illnesses into 'effects' i.e. "Digestive system" or "Legs \ Lameness" etc There are tables of illnesses and injuries that can affect these areas and plenty of photos (this isn't a book for the kiddies or the weak of stomach).
Next is a section which goes through things alphabetically and finally there is a section which I didn't think really fitted into this type of guide, which had various protocols and processes which may be useful for studs or barn owners when dealing with various illnesses.
Because of the repetition - by area and then alpha - I didn't think that the topics received as much indepth coverage as perhaps I had wanted - the information on treatments, drug protocols etc was rather light IMHO. Although this cross-referencing system is designed to help you to work out what is wrong with your horse, I'd much rather that it was assumed that any serious illnesses would be diagnosed by your vet and that this would then be a reference for dealing with illness and injury at home and for helping owners to talk intelligently with their vet about available treatments.
Overall a handy book to have and certainly one that I will use for reference from time to time but I don't know that it warrants the subtitle "A comprehensive guide to Horse Health"
