Never allow a puppy to put his mouth on you, even playing. So every time you must give a verbal correction. I use a noise like "eeeh! Sisco or crack. One important and immediate quickly became his attention. Also be followed with an order to calm him. I use "set" and make him sit or lie until calm. It requires diligence on your part, but will get it later.
