Hi, I have a 15h quarterhorse that I just rescued and I am haveing trouble with him bolting on the lunge line. When I first got him I tryed lunging him with just a 12 foot lead rope and a rop halter. Well that turned out not so good. He will start out ok at the walk for about 2 second and then before you know it he bolts off to the outside and rips the lead out of my hand. So then I decided to put a loose ring single jointed snaffle in and I took my lunge line and put it up through the bit , over his ploe and attached it to the outside of the bit. After doing all that it still failed. He is extremly quik and strong. This is the srongest short stout horse I have ever worked with. When he bolted with just his rope halter I decided that it was time to learn in the round pin. Do you have any other ideas? I have been depating on using a chain or just keep dooing what im doing? Any ideas?
