First off Welcome to EBN you just became a member of the greatest EB community EVER!!! Secondly i am so sorry you are having these issues with your baby boy. I would recommend asserting your dominance with him. Flip him over on his back hold him down with your hands on his underarms and with a very serious face stare into his eyes. He may wiggle and struggle but DO NOT let him up until he looks away from you an submits. I recently had to do this with my puppy who is 9 mnths old. Also anytime he gets a little to rough during playing, again be stern and serious and say PSSST!! you can clap your hands when you do this too. Also a time out NEVER hurt. Put him in his crate when he starts to get rough to let him know if he can't play nice....he can't play at all. I am sure you will get ALOT more info. Hope this helped!!
