I start all of my colts in a hackamore, and continue to ride them in a hackamore for their first 10 to 15 rides because it gives them a chance to learn how to give and soften to pressure while I’m up on their backs without having to deal with a bit just yet. It also allows a smooth transition for a colt going from responding to a halter on the ground to responding to the same type of pressure under saddle. My theory is: The softer you can get a horse in a hackamore, the softer he’ll be in the bridle.
The hackamore is also more forgiving and allows for mistakes on the rider’s part. In the early stages of riding, especially for more inexperienced riders, you don’t want to haul on the colt’s mouth or pull when you shouldn’t be pulling. If the horse is wearing a hackamore and you accidentally pull when you’re not supposed to, you’re not going to damage his mouth.
