Can a reining horse be converted to working cow horse?

A reining horse can be transitioned into working cow horse competition, and in fact many horses compete successfully in both disciplines either simultaneously or sequentially, because the reining foundation required for the reining phase of working cow horse is identical to reining competition training and the cattle work can be added to an already-confirmed reining horse. The practical question is not whether the conversion is possible but whether the specific reining horse in question has the natural cow sense and athletic ability to produce competitive cattle work — because the reining foundation, regardless of how deep and correct it is, cannot substitute for the cattle-working instinct that genuinely competitive cow horse work requires. A reining horse with excellent training, a confirmed stop, spins, and lead changes, and the natural cow sense that was never developed because reining training did not require it, may transition beautifully to working cow horse when cattle are introduced — the training is already in place and the natural instinct emerges when cattle are presented. A reining horse with excellent training but no natural interest in cattle will become a working cow horse competitor in the sense that it can complete the pattern, but it will not produce the instinctive, athletic cattle work that generates the scores available to a horse with genuine cow sense. The transition process for a reining horse with natural cow sense typically begins with the systematic cattle introduction program used for young prospects, moves through the development of boxing and fence work skills, and builds on the confirmed reining foundation rather than having to install it alongside the cattle work, which makes the process faster than starting a horse that needs both.
