Colt likes to nip. Owner doesn’t play that game

Gunner is29 months old and likes to play. His game is to try to nip so you will swing at him to dodge. It’s the same thing he does to Little Bit. The other mare in the pasture. It’s all for fun but no one want to get nips. Instead of swinging to hit him I just hold his mouth or chin so that he can’t bite me. He has gotten so much better with me. But if he can get someone else to think he’s going to bite , he will.
