Gosh please don't give up!! What about my baby? He is 4 months old and I just got him, there is no way he has been overy socialized and so I do bring him places that I can bring him, and I always tell people to just go and pick him up (when they come over). I can see Chico get nervous, but I keep talking to him in that "baby" voice we give our chi's (you know you all do!), but I just keep talking to him while others are picking him up and then I slowly stop. I think this helps. I understand though if you don't have much company. Maybe now would be a good time for Puppy Obedience school, this helps w/socialization w/other people and dogs.
