Zeke is CONSTANTLY nipping or biting Jo. She does like to play with him, however, not ALL the time. She can't go outside for a pee or whatever without Zeke at her. I have no idea what to do. I tell him to stop, and he goes right back at it. She even yelps sometimes cause he bites at her so hard. The most she does is snap at him and growl, but that doesn't even stop him. I just let her out to use the bathroom, then let him out but still..any sugestions?? Thanks
