How do I train the horse for steer wrestling and what qualities make a good bulldogging horse?

The steer wrestling horse has one of the most specific and demanding jobs in all of timed event rodeo — it must leave the box with explosive acceleration, run alongside a steer at full speed, allow the wrestler to slide off its side at the correct moment, and then continue straight without drifting, slowing, or reacting to the sudden loss of the rider's weight. That combination of explosive speed, steady positioning, and post-drop behavior is rare, and the horses that possess it reliably become among the most valuable athletes in rodeo. The essential qualities of a bulldogging horse begin with speed — genuine, explosive acceleration from a standing start in the box to full stride in the first few jumps. A horse that takes several strides to reach full speed is losing the wrestler critical feet on the steer before the approach even begins. Quarter horses with strong sprinting genetics dominate the event because that explosive short-distance speed is bred deeply into the best of the breed. Steadiness alongside the steer is the quality that is most difficult to find and most important once the approach is established. A horse that drifts away from the steer during the approach creates an impossible reach for the wrestler; one that crowds the steer forces the wrestler off at the wrong angle. The ideal bulldogging horse runs in a perfectly parallel line beside the steer at the correct distance throughout the approach. The post-drop behavior — what the horse does after the wrestler leaves the saddle — reveals a horse's true suitability for the event. A horse that continues straight, slows gradually, and comes to a stop without veering is a horse that can be safely used run after run. One that shies, spooks, or veers dramatically after the drop creates hazards for the fallen wrestler that no amount of other quality can compensate for.
