What should you look for when buying a finished working cow horse?

Buying a finished working cow horse requires evaluating the horse against a more specific and demanding standard than most horse purchases, because the specific combination of reining training depth and cattle-working ability that defines a genuine cow horse is not visible from a single demonstration ride and requires a thorough evaluation across multiple dimensions. The most important first step is watching the horse work cattle with its current rider or trainer before getting on it yourself, because the difference between a horse that works cattle well for a skilled professional and one that transfers its cattle-working ability to a different rider is significant and is best assessed by seeing the horse perform and then riding it yourself in a cattle work situation — not just in the arena without cattle. The horse's reining foundation should be evaluated specifically by riding it through the reining maneuvers: the stop should be soft and willing without requiring significant rein, the spins should be correct and responsive, the lead changes should be clean, and the circles should show genuine rate control. Any significant gap in the reining foundation will limit the cattle work regardless of the horse's natural cow sense. The horse's cattle work should be evaluated against the level of competition being targeted — a horse that is excellent for amateur cattle classes may not be competitive in open classes, and being honest about which level the horse's ability genuinely supports prevents the disappointment of a purchase that does not match the buyer's goals. A thorough prepurchase veterinary examination including radiographs of the key structures stressed by working cow horse performance — hocks, stifles, feet, and back — is as important as any riding evaluation.
