Reining is a western riding discipline similar to dressage that involves precise maneuvers like circles, spins, and sliding stops performed at different gaits including fast gallops and slower lopes. Competitors must demonstrate control by either rolling back or performing a sliding stop from a gallop. A rollback involves an immediate 180 degree turn after stopping, followed by loping again. Horses are judged on precision, smoothness, and finesse, with scores ranging from 0 to 70. Quarter Horses excel in reining along with other western breeds like Paints and Appaloosas.
