what is reining horse
Reining is a western riding competition for horses where the riders guide the horses through a precise pattern of circles, spins, and stops. Circles: the horse must perform large, fast circles at a near-gallop and smaller, slow circles at a lope. 2  They should be perfectly round, with the rider dictating the pace of the horse. 3  There should be an easily seen change of speed as the rider transitions from the large, fast to the small, slow circles.
