So for the last year and a half my horse has been leased out while I was in school. When I left him he was sweet, gentle, was able to be tacked up easily and was just the sweetest thing. This past weekend I got him back. He is pushy, hates being groomed to the point of kicking out at me. He won't stand tied patiently and he dances around the entire time the halter is on him. Even rubbing my hand down his neck he pins his ears, starts swishing his tail and picks his back leg up to kick at me. Today it took me 20 minutes to brush just his neck before he would even remotely calm down, but even then if I would move my hand to say his chest the problem started all over again. And saddling is completely out of the question. He kicks out, he steps sideways, pins his ears and throws his head up at the first sight of the bridle. He is 14 years old ottb. He is 17.2 hh and I'm 5'2 on a good day. Ugh what could be the issue??
