Quarter Pony
The Quarter Pony is a breed of pony that stands up to 14.2 hands (58 inches, 147 cm) high, and was developed from American Quarter Horses that did not meet the height requirement for breed registration. It looks like a small Quarter Horse, although a few of the breed registries also allow crosses with other stock horse breeds such as the Paint horse, Appaloosa and Pony of the Americas.
