 In 1983 a number of Appaloosa breeders opposed to the registration of solid-colored horses formed the American Appaloosa Association, a breakaway organization.Appaloosas are used extensively for both Western and English riding.Western competitions include cutting, reining, roping and O-Mok-See sports such as barrel racing (known as the Camas Prairie Stump Race in Appaloosa-only competition) and pole bending (called the Nez Percé Stake Race at breed shows).
