turn around green horse

Its been really working good to make the hind end go out of gear by inside leg and hand to the opposite shoulder. then atadding outside leg and letting them drop down nose first into the turn. If they look to the outside take the hind end out again the try again with the outside leg until the quit looking the wrong way. I go back and forth and back and forth- getting the hind end out of way then letting the front drop into the turn around nose first with the shoulder up. When I quit the drill I want them to stay hooked into the circle to the direction we are working on because they arent going to turn around in the first place if they cant walk a good circle on their own without much help. This drill really helps them hook onto that circle.
