How do I train a rope horse to have a reliable stop?

The stop is the single most critical response in a rope horse and the one that most directly affects the roper's ability to dally safely and secure the catch. A stop that is late, crooked, or requires hard pulling to produce is a stop that costs time, creates dally danger, and puts stress on the horse's joints from repeated hard deceleration without correct form. Building a correct stop begins at the walk and trot long before the lope, establishing that the horse responds to a seat and weight shift cue before the rein is ever applied. Sit deep, say whoa, and release all leg pressure — the horse should slow and stop from that combination before the rein is needed as a reinforcement. At the lope, the correct stop has the horse driving its hindquarters under its body and sitting down into the stop rather than falling on the forehand. This requires that the horse be moving forward with impulsion and engagement before the stop is asked — a horse loping along on the forehand with no hindquarter engagement cannot produce a correct stop no matter how hard it is asked. Vary where on the arena you ask for the stop so the horse does not anticipate it and begin breaking down early. After the stop, ask the horse to hold its position rather than immediately walking forward — the horse should stand square and wait for the rider's cue to move. Never punish a horse during or immediately after a stop; the stop must always be associated with release and reward or the horse will begin to dread and evade it. The stop is built over months of correct repetition, not created in a single session.
