So my 10 week has developed a sick game. He runs after and bits my arms and hands, enough for it to hurt. At first I tried what people suggested, mimicking a squirrel pain sound since it is a grooming habit. Now he constantly chases my skin to bite me. I yell, I spray him with water, I push him away, AND HE LOVES IT. It just makes the game more fun to him. I can't handle this game anymore and if it continues I will not be able to keep him around. HOW DO I STOP HIM! I'd like to clarify his behavior is not aggressive in any way, it's simply a game for him.
