I went bac and looked at the photos and the running martingale on this horse is set up dangerously. ALWAYS put rein stops on the reins when using a running martingale so the rings of the martingale do not slip close to the bit. When they do, they can become stuck there and the horse can "hit" the martingale restriction and really get jammed up (or hurt).
I knew someone who used a running martingale without rubber rein stops and they were in the line up waiting their turn to jump and the horse ducked his head and the martingale leather ended up in the horse's mouth.. the horse raised his head and felt suddenly trapped. Flipped out and over backward. Girl was killed.
I rarely used a martingale. It was better to train the horse. I always used rein stops with a running martingale. Better to leave it off if you do not.
