I have mostly questions but I hope they will be helpful:
It seems like every instance of explosive behavior happens on the lead, right? Could it be something like a sensitive tooth or a painful facial nerve? Damage/injury to his poll? Or how about EPM, doesn’t that involve the nerves?
How about painful ear plaques, bugs, or an ear infection?
Eye infection or incipient blindness? Does he always explode going one direction or has it happened when he is being lunged both ways?
I’m thinking about the issue of pressure on his face, head, or neck: have you lunged him freely without a halter or lunge line and had this happen? I realize that may not be safe, given his behavior. Has he had major explosions under saddle or only on a lead? Have you tried a neck collar only (again, less control, so maybe that is not safe).
If it is a behavior issue, he will control himself around dominant people or animals, unless he had that bad social start like the stallion on the Buck Branaman movie. That horse had been hand raised and given no boundaries by people. Sometimes those bottle babies have no skills around other horses either, because they weren’t raised around them. One other thing: if it is a behavior issue and a trainer was able to get him to behave, would you be able to trust him without the trainer around? I’m wondering how well this aggressiveness can be controlled by training if it is a behavioral problem.
The brain tumor sounds possible, too, but with a brain tumor, the bad behavior will probably start to occur more randomly, not just in specific environments, and the crazy behavior will escalate as the tumor grows.[/QUOTE]
Facial issues were never thought of but could look into it. I used to lead him with a chain, but I never shanked it. I had a hunch maybe someone has, so I’ve since started using a plain lead. Generally when leading there would be no pressure on the lead/halter unless he began to freak out. But only pressure, no yanking.
It seems to be more of an outside-stimulus that sparks the explosions. He’ll lose his focus on me/handler and the task of walking somewhere and begin to worry until he explodes.
Behaviors don’t really happen under saddle. Every now and then we’ll have a bad day or 2 but then he’d shake it off and have a good few weeks of productivity. It is mostly in-hand that is the problem.
