What is working cow horse and what does it take to compete?

Working cow horse is a western performance discipline that tests the horse's ability to control and dominate a single cow through a fence work phase that requires the horse to run the cow down the fence, turn it at each end, and demonstrate authority over the cow's movement — as well as the reining and boxing components that complete the full working cow horse competitive entry. It is one of the most demanding and most thrilling of the western performance disciplines to watch because the fence work phase is genuinely athletic and genuinely unpredictable, with the outcome depending as much on the cow's athleticism and willingness to fight as on the horse's training and the rider's skill. The fence work is the defining component of working cow horse competition and the phase that most directly tests the horse's instinctive athletic response to cattle. The cow is released at one end of the arena and the horse and rider have a limited time to demonstrate fence work — running the cow down the fence at speed, turning it at the fence end, running it back in the other direction, and turning it again. The quality of the runs and the turns, the speed and aggressiveness of the horse's response to the cow, and the degree to which the horse dominates rather than simply chases the cow are all evaluated by the judge. A horse that gets behind the cow, that misses turns, or that allows the cow to escape past him loses the scoring opportunity that the fence work phase represents. Competing in working cow horse requires a horse that has both the reining foundation for the dry work component and the natural cow sense and physical athleticism for the fence work. These qualities must be genuinely developed rather than simply present in potential, which means the competitive working cow horse is typically the product of several years of systematic training in both components before competitive entries at any meaningful level are appropriate. The horse must also be physically sound and athletic enough to sustain the demands of fence work — which involves explosive acceleration, sharp turns at speed, and the physical contact of stopping and pushing against the fence — without the wear that inadequate preparation or premature competition causes.
