When another horse goes blind in a herd, a sighted horse accepts responsibility for the welfare of the blind horse and guides it with the herd. With humans, many blind people ride horses in equestrian competitions. Some blind people ride alone on trails for many miles, completely relying on the horse to guide them safely to their destination. Through history, Cavalry horses have been known to guide their injured rider to safety. Cavalry horses have proven that horses can remain calm even in the extreme heat of battle.

Guide Horses undergo the same systematic desensitization training that is given to riot-control horses. Great Memory - Horses possess phenomenal memories. A horse will naturally remember a dangerous situation decades after the occurrence. Because horses have eyes on the sides of their heads, they have a very wide range of vision, with a range of nearly 350 degrees. They also have outstanding night vision and can see clearly in almost total darkness.
