How do you develop collection and softness in a mustang?

Developing collection and softness in a mustang follows the same progressive principles as developing these qualities in any horse, but the specific foundation of trust and lightness that effective mustang training builds often creates a particularly receptive starting point for collection work because the horse has learned from its first training experiences to respond to very light pressure rather than waiting for strong aids. Collection in the mustang context is not the artificial head set of certain show disciplines but the functional self-carriage and engagement of the hindquarters that allows the horse to balance itself under the rider's weight with lightness in front and power from behind — the same balance and efficiency that the mustang used on the range to navigate terrain with minimum energy expenditure. The foundational collection exercises — transitions, particularly downward transitions that ask the horse to engage the hindquarters rather than fall onto the forehand, circles that develop balance through a curved path, and lateral exercises that develop independent control of the hindquarters and shoulders — are the same exercises used with domestic horses, and many mustangs respond to them with particular quickness because their natural balance and self-carriage on varied terrain has already developed the physical coordination that these exercises further refine. Developing softness in the jaw and poll — the horse yielding to rein contact with a soft, giving response rather than bracing and pulling — is developed through consistent use of light rein contact that releases immediately when the horse softens, teaching the horse that softening produces release and that bracing produces maintained pressure. The mustang's sensitivity to the handler's energy and body position, developed through the gentling process, often makes the seat and weight aids of collected work particularly effective because the horse has been conditioned to respond to subtle body language signals from its earliest training.
