I am not sure if this is the right place for my question, but since it is a trail issue, I thought I would start here.
I have a horse that does not like being crowded or passed out on the trails and sometimes expresses this by turning his rear and kicking without warning. He has been run into by another horse on at least one occasion and I do believe the kicking out is his way keeping this from happening again. He doesn’t mind walking along side other horses or if they come at him from the front, but it seems if another horse comes at him from the side or rear, he occasionally goes on the defensive.
Any recommendations on how to desensitize him without getting another horse or person injured?
