Originally purchased this book as a preparation for an equine bodywork class and now carry it around and refer to it quite a bit. If you want to understand which part of the horse's anatomy is used for which purpose and even how to ensure the anatomy stays sound; if you'd like to explore where different parts (bones, muscles, ligaments)are located, what they are called and how they interrelate with the rest of the anatomy, this book is an invaluable resource. The drawings are intentionally 'mechanized' to show how the horse's anatomy WORKS. This book, in my opinion, is a valuable tool for anyone who works with horses on any level or who has a serious interest in the wellness of their horse.
