The Tennessee Walking Horse or Tennessee Walker is a breed of gaited horse known for its unique four-beat running-walk and flashy movement. It was originally developed in the southern United States for use on farms and plantations. It is a popular riding horse due to its calm disposition, smooth gaits and sure- footedness. The Tennessee Walking Horse is often seen in the show ring, but is also popular as a pleasure and trail riding horse using both English and Western equipment. Tennessee Walkers are also seen in movies, television shows and other performances (Wikipedia).
