Uhg, I'm not going to contribute to the hijacking that might be in progress here.... ;) I know you did right by that horse by asking his permission, good for you for doing things right!
I think this is a good opportunity for you. Sounds like he is pretty challenging...LBE/RBI? Wow, I'd like to get my hands on him! lol. All that displaced behavior....pawing, grinding teeth....is introverted behavior showing extreme stress (mental and emotional for him). The sweating his showed while riding was not because of physical stress, but because of mental and emotional stress. Once he was treated correctly (when everything was done FOR him, not TO him) he didn't sweat (hmm, how interesting right?!).
I am not going to disagree with you, but I am going to say that NH/Parelli has a place, and only after the horse understands that you're the one running the show. If you come in and automatically try to be an equal partner in the relationship, then you can not be one who has more power, because then you might actually have to "force" your horse to do something it might not "want " to do.
I would really love to hear your opinions on my gelding (no sarcasm here, completely genuine) and so for the sake of not hijacking the thread futher, feel free to just PM me about it. My gelding is an 11 year old OTTB, who came to me as sweet as could be, but it was quite obvious that he was running the show at his house, and that his previous owner had never tried correcting it because she never had a chance to ride him or work with him. She was his source of food, and that's it. When I brought him to my barn, it was immediate work. I put him in the round pen, we taught him how to lunge, I groomed him daily....in other words constant contact from me. After a few weeks we were riding in the round pen in addition to lunging. He originally hated the bit I had him in (a simple d-ring jointed snaffle) so I switched him to a hackamore, and he improved dramatically. All the while his personality was taking a down turn, and it became a fight to even put his halter on to bring him out of his stall. He was attacking and bullying other horses, or getting bullied around to the point of injuries that made him unrideable. He would bare his teeth and lunge at any human who he thought was someplace they shouldn't be, and even bit a few people. I had been doing things like "asking his permission" to which he would give me the non-chalant look away, but then when I actually brushed or saddled him up or whatever, he would turn and pin his ears at me. So, I switched and one day when he lunged at my BO we had a showdown right in the front yard. I screamed, I yelled, I backed him up a good twenty feet and I jerked on the leadrope so hard it could have given him whiplash. He was obviously surprised at my reaction, but he still tried it three more times, along with little things like a one-step space invasion. Each test got a huge reaction. He hasn't had a problem with biting or being pushy since. As for the stall aggression, I went and I found myself a crop, and when he was disrespectful to me (like continually eating even though he saw me standing there) I waved it around and smacked things (not him) and gave him only one option: me. After a few weeks of that, he'll put his nose right through the halter. He is a habitual cribber, even with a miracle collar. He paws on occasion in crossties, but that's usually when I'm taking an extra long time tacking up. He is an LBI horsenality type.
So, I didn't "force" him to do anything, but I definitely wasn't nice about it. It was do what I wanted, or nothing at all. And he's very happy now. He approaches me in a paddock and he's willing under saddle. I'm his leader and he respects that. So, assuming you'd had my horse, what would you have done differently to address these issues?
