Hello! Hope everyone has a good thanksgiving!
I have had my 5 year old ottb for about 6 months now. In the past month or two, he has gotten more and more aggressive while grooming and tacking. I will occasionally catch him pinning his ears when I walk past his stall. He is usually outside from 7am-5am, and gets ridden about 6 times a week. He used to NEVER be aggressive, just a little sensitive while grooming and tacking.
He hasn’t gotten to the point of actually harming me, but he bites the air/his stall, pins his ears, and bobs his head significantly when I brush/tack him up. His back is not sore, and I am pretty sure he doesn’t have ulcers. He is usually tacked in his stall with access to hay prior to his ride. He is never aggressive around food, really only when I’m tacking.
PLEASE help me catch this in the bud, as I do NOT want an aggressive horse, especially with him being so young.
