its a chi thing--you dont want to encourage rough play ever as that is a "rank" type of move......Have you tried any training with him? Sometimes no matter how well a puppy is socialized you can still have problems (not sure how you socialized him) but chis are generally 1-2 people dogs and are very loyal and protective.
Have people give him treats and things and approach him in a gentle calm fashion. Giving praise when good behaviour is achieved. Lots of old threads about this too. :wave:
