How do you teach a heel horse to stop correctly?

Teaching a heel horse to stop correctly is one of the most important and time-consuming parts of its development, and the foundation must be built in the arena without cattle before the stop is ever asked in the context of a run. A correct stop begins with the horse understanding and responding to the rider's seat: the rider sits deep, drives the hips forward, and ceases leg pressure — and the horse reads those cues as the stop signal before the rein is ever applied. This seat-first stop is not a fast stop in the early stages but it installs the correct biomechanical response — the horse driving its hindquarters under its body and sitting into the stop rather than falling on the forehand when the rein comes. Build the stop progressively: walk to halt, trot to halt, lope to halt, each cued by the seat first and reinforced with the rein only if needed. The horse that stops from the seat at the walk with lightness will carry that response forward as speed increases if the progression is patient and the release comes immediately when the horse tries. When the stop is confirmed in the arena at the lope, introduce it in the context of a run on slow cattle where the heeler can practice asking for the stop at the correct moment — the instant the loop clears the heeler's hand and the dally begins. The timing of the stop ask matters as much as the stop itself: a heel horse asked to stop a stride too early loses ground before the catch is secured, and one asked too late is already past the correct stopping point. The repetitions required to make the stop automatic under cattle pressure are significant, but a stop built correctly from the seat up will hold under pressure far better than one built primarily from the rein.
