Milo has been play biting since I got him, but recently it's been getting really bad. When he bites, it hurts and I yell "ouch" or "no" and my boyfriend usually growls at him :P But tonight when I yelled at him, he completely turned on me and was getting really violent. He started growling and biting really hard. It was almost like he was trying to dominate. I don't know how to stop him from doing it. We've tried the yelling, putting him on time-out, ignoring him, giving him toys instead of our hands and nothing is working.
Has anyone had this problem? If so, how did you deal with it?
