How do you teach a helper to assist with mounting safely and what are the risks of doing it incorrectly?

Clinton Anderson addresses assisted mounting because it is commonly done incorrectly in ways that create problems rather than solve them, and because a helper who does not know their role can make a difficult horse more dangerous rather than less. The most common incorrect helper behavior is standing at the horse's head, holding the lead rope or the bridle, and trying to hold the horse still while the rider mounts. Anderson teaches that this approach fails for two reasons: a helper at the head cannot stop a horse that genuinely wants to move — the horse will simply drag the helper — and a helper holding the head is positioned directly in front of the horse, which is the kick and strike zone if the horse does react. Correct helper positioning for mounting assistance is at the horse's shoulder on the near side — the same side as the rider — facing the horse's hindquarters. From this position the helper can observe the horse's hindquarter tension, can step toward the hip to block a swing if needed, and is out of the danger zone at the front. The helper's job is to watch the horse's body language and communicate calmly — not to restrain the horse. For a leg-up assist, the helper should be positioned at the rider's knee with cupped hands, providing the lift in a single smooth motion as the rider signals, rather than an unpredictable or jerky boost that can unbalance the rider at the critical moment. Anderson's broader teaching on helper-assisted mounting is that a horse that requires a helper to be mounted safely has a mounting problem that needs to be trained, not a mounting problem that should be managed permanently with a helper. The helper is appropriate as a temporary safety measure while the training is completed, not as a permanent management strategy.
