The Tennessee Walking Horse was created by mixing the genes of the Narragansett Pacer, Canadian, Morgan, Standardbred, Thoroughbred and American Saddlebred. These horses stand 14.3 to 17 hands tall, and their body features a long bottom line. They have elegant heads and small ears. Tennessee Walking Horses come in a diversity of color patterns, and they perform three gaits: cantering, the flat foot walk and the running walk.
