Training Self-Loading with Positive Reinforcement

This video assumes your horse is already a competent and confident loader! Before you attempt to teach your horse to self-load, I recommend you spend time practicing loading with your horse in your normal way before attempting to send the horse on alone.
If you are working by yourself, like I am here, you may want to set the trailer up with treats so that the horse can instantly reward themselves as soon as they load (rather than waiting for you to come around to reward them)
Good luck!
