The same rules should be observed for making a horse canter with the right leg, but the right rein should be only drawn enough to develop his right nostril.

Reining Back. You must collect a horse with your legs before you rein him back, because if you press him back first with the reins he may throw all his weight on his hind legs under him, stick out his nose, hug his tail, and then he cannot stir you must recover him to his balance, and give him power to step back. This rule is often neglected by carters in trying to make the shaft-horse back.
