aqha13~he doesn't yield to pressure at all. He will push into you and he will not give up! I've stood there for 45 minutes pushing a finger into his hindquarters and I am usually the one to give up (bad I know) I would brush him but I don't think he enjoyis it. Because as of right now he has a bad case of Rainrot that we are trying to get rid of. So of course brushing hurts for him right now.
NittanyEquestrian~ I do have a lungeline and lunge whip. So just never really used them. He does backup well under saddle. And you can back him up with his halter. We definitely don't beat him. But as I said he isn't scared of anything. Including a whip. I use the whip to help desensitize him. As he didn't like the hindquarters being touched what so ever.
As for trying to get him to yield his rear. You mean kinda walk in a circle with him. While pointing and telling him to move his butt? I'll see if I can find some clinton and parelli videos as well.
I think I have finally bitten off more than I can chew with this guy. However he is absolutly wonderful when he isn't around his grain. We are teaching him to ride. And he has been ridden about 6 times so far. And he is doing fantastic. My little brother is the one riding him. Sometimes he'll be a little head strong. But we are working on it. I'm really hoping we can get past the aggression and he can become a well mannered horse!
