He pins his ears when you're simply next to him in the grooming stall,
Chases down and shows interest in attacking other horses when riding, HATES doing much more than trotting around (still has issues with even that)
And don't try using any more than a brush with your legs
Hates getting groomed,
Hates having much to do with anybody if it doesn't involve getting food, going out to the field, coming back in to his stall, or little kids, he loves kids (although I don't trust him enough to be around them)
He's seen several vets who can't give a reason medically why he's so upset, he has his own chiropractor and acupuncturist, we've tried massage, saddle fitting, diet changes, we've treated for stomach ulcers, we've injected his hocks, we've done 4 chiropratic visits, 2 accupuncture sessions, we've changed his shoes, we've changed his bit, we've tried everything I can think of.
We tried the behavioral stuff, tried natural horsemanship approach, tried the more aggressive dominance battle techniques, we've tried just ignoring his behavior to see if he's looking for a reaction, we've tried running him out of it, we've tried making bad behaviors hard and good ones easy, we've tried food incentives, we've tried it all.
WHAT HAVE I NOT THOUGHT OF?
I would love to hear something new that I can try and figure out what is going wrong to make him so angry. He's very dominant, and while he never actually bites or kicks, he tries to fake you out, and wears one of those ugly ears pinned, lip curled faces like a favorite outfit. I'm going mad with this!
He's extremely talented and when he's on, he's on. He can soar over 4 foot fences like they're nothing, he's fearless and can give you the best trail ride you've ever experienced, he's wonderful to kids who want to pet his face, and when he's not angry, he is the sweetest horse I've ever met, I just want to know how to fix our problem, what am I doing wrong?
