The Tennessee Walker or Tennessee Walking Horse is a gentle and comfortable riding horse. The breed was originally bred in the Southern United States to carry the owners of plantations around their lands. A closely related breed is the Garrett Walking Horse. Their unique four-beat running walk is especially comfortable to ride, making the breed a well-suited trail companion. The breed is rarely seen in any of the sport horse disciplines, however, they are good for trail riding because of their smooth gaits, stamina and easy temper, and are also seen in Western riding disciplines and in harness. Base size is 7 W X 3 D X 1.5 H.
