I bought my horse in November of last year. He is a 3D barrel horse that was used in high school rodeo by a girl the same age as me. (I'm 19) When I bought him, I specifically asked her if he had ever reared and she replied saying "only small bunny hops towards the barrels, never away from them" verbatum.
Now. He is a habitual rearer. Personally, I don't believe he is a "confusion" rearer or a "scared" rearer--I think he does it out of malice. As if to say, "Get OFF my back RIGHT NOW!" He is 14 years old and is spook proof. He is "trained" and knows his job, I never ask anything complicated from him anyways. Never spooks at anything to rear over!
He loves to rear when you turn him away from other horses (buddy sour), he also rears when you ask him to back up, and gets incredibly INSANE when you run barrels on him or plain ole' ride him for too long in one session. I've got a vet check on him, all is good. I've even had a chiropractor out to check his back.. perfectly healthy! He is not hurting.
I hate to say this, but I'm scared of my own horse. He rears while I ride him, while my friends ride him, even while trainers ride him. Any advice? How do I go about selling a problem horse like this if it is out of my league to "fix" this? Who would buy him?! Could I get sued for selling him and he possibly hurting his new owner?
I've heard all the quick fixes: eggs, water balloons, hitting him on the way up, turning circles (that was lovely, we were sideways and up in the sky), everything. Before recently he would only rear a few feet off the ground, but the last time he reared he was a 90 degree angle to the ground and I abandoned ship. I honestly believe if I had not jumped off, he would have flipped over on me.
What do I do?! I am open to ALL suggestions--even selling him.
