An understanding of the desirable and undesirable conditions found in horses, together with a knowledge of their relative values, will enable the purchaser to select a better animal, with a considerable saving of time, inconvenience, and expense. A thorough examination for the various forms of blemish, vice, faulty conformation, and unsoundness in a horse is absolutely essential if serviceableness is to be secured, and a definite method of procedure should be adhered to in making the examination, which should correspond to the order in which the various steps most conveniently present themselves.
The horse’s head is large, with eyes set wide apart at the sides of his head; he seldom sees an object with both eyes at the same time and generally sees a different picture with each eye. In the wild, this double vision was a big advantage, making it difficult for a predator to sneak up on him. He can focus both eyes to the front to watch something, but it takes more effort. Only when making a concentrated effort to look straight ahead does the horse have depth perception as we know it.
