UPDATE: We worked him earlier using the methods/advice from the forum, with GREAT results!! For the lunge, we used the rope halter w/ 10' lead and a second hand, he followed her every move. By the third change direction, he did it completely on his own! He never got excited/nervous/agitated, stopped halfway through my whoa, and started walking the second I asked him. He did GREAT! Afterwards, we let him graze a bit, and then walked around just dragging the whip on the ground on the other side of us. He watched it for about 5 minutes, then ignored it. We did this for a while and got closer and closer to him with it, and then started having it brush his feet. NO REACTION! Finally we stopped him and started moving it up his body, hooves first. He stood there like the horse in the video... honestly I was shocked! By the end we could touch his ears with it, "crack it" next to him, rub it all over, no problems
He started, maintained, and ended his lessons without any fight/flight/fear, which is a first for us. We put him back in the pasture and just went out for feed time, he normally charges the fence and races to his feed pan, this time he stopped and greeted us, then made his very calm way over to his feed spot.
Tiny, he does stand very well when tied, unless he is spooked, then he really flips out and tries to break free. When he cannot, it takes about a minute for him to relax. I will definitely work on bending in tomorrow's lesson as what you said makes great sense. He leads well, but I think your right, not because of pressure, but he just wants to follow whoever has the lead.
Pat, thank you for the Parelli link, just reading it over before posting this, I think those exercises, or games, will work wonders on him. He is ok with the "porcupine" but usually at a high pressure level. I will continue to work on this with him, and now I feel MUCH more comfortable with the next step, the "Driving".
Again I thank ALL of you for your advice, it REALLY made a difference today when we worked him!!
