Shake him sharply by the scruff if he tries these things, just as his mother would do. And of course, always praise him lavishly in a quiet tone when he relaxes. Now is also a good time to handle all four paws and look briefly into his mouth so he can get used to tolerating your handling him gently. Be sure to do this exercise 4 or 5 times a day at first. Taper off as the pup gets more used to you and accepts your leadership.
Eye contact is also one of the ways order is kept in a wolf pack.
Only an alpha animal may use it to remind everyone who is in charge. When you initiate eye contact, you express your alpha position. Encourage your pup to maintain eye contact for several seconds, making it a pleasant experience. Do not force him to do so. However, you do not want to try to do this with a dog who thinks he is already in charge of things.
