When I have him tied where he can't see horses, he goes bonkers. Hollering, head high, ignores his handler... will sometimes paw, and he moves around constantly. I can usually get his attention if I grab a carrot stick and tap his rump with it and PUT him where I want him (standing correctly where he's tied) but as soon as I put it away he is back to acting up.
When I ride him, I can ride him away from the horses just fine, at any gait/speed I want, without any problems at all. Even walking back, he doesn't fight. It's just if I stop him and ask him to stand still while he's out there. He won't do it. He'll back up, duck his head down, side-step... He won't try to take off, but he'll fight me. He hasn't reared or bucked or anything, but I want him to stand calmly.
He has shown lots of little disrespectful habits like this since I've started working with him. Right now he's in the barn my himself where he can't see or interact with other horses. He usually stays out with everyone else, but tonight after bolting out of the barn to get to the other horses (running me over in the process) I decided I need him to get over this sourness. Not sure if secluding him for a while is the right route to take, which is why I'm asking for advice here.
Thanks in advance!
