Working cow horse is a type of competition, known also as reined cow horse, where horses are asked to work a single live cow in an arena, performing specific maneuvers that include circling the cow, turning it in a specified manner, and performing a reining pattern. Horses that can perform these tasks are called "reined cow horses," "cow horses," "stock horses," or "working cow horses." Competition consists of three parts where a horse and rider are judged on their performance in a reining pattern, herd work, and "fence work". Horses are judged on accuracy, timing, and responsiveness, as well as how they handle a single cow and their ability to ride into a herd of cattle and quietly "cut" a cow from the herd.
