7 years? 7 years?
and he's still doing it? What the heck? JustSam is right -- it's a respect issue if he's doing it just when someone walks by. The horse needs some serious mediation work. Yes, indeed, smack him in the mouth when he bites and when he tries to bite. When he gets his muzzle anywhere near you, push him away even if he is not biting. You and all others around him must NEVER let him move his muzzle to you. Only you can move to him. But that might take a while.
One of my horses was pretty domineering about her space when she came here. She was a wannabe biter. She was just at the point of trying it out (actually did get my clothes a couple of times), so I made sure to stop her whole attitude right quickly: Anytime I was in the field, she wasn't allowed to come into my space. My space is now defined by the length of my arms, it used to be the length of my arms plus a crop. If she came into my space without my invitation she was sent away. EVERY TIME and with WHATEVER IT TOOK. When I was grooming her or doing her feet, if her head came my way at all, I'd elbow her or push her or bump her. If she actually tried to bite, she got smacked on her mouth and I'd be right in her face physically and verbally. When I
was ready, then I would move into her space and be all nice to her. Currently, she is a big suck and loves to have her head rubbed. Your horse will not become head shy if you enforce the difference between him moving into your space and you moving into his.
