Definatly take him to the vets for a check up, the wobble sounds worrying. He's not a chocolate but very cute. Its unfortunate that you did not see his parents, I personally would not buy a puppy unless I had at least seen the mother. He's a sweetie and deserves a good home so as you already have him, I think you should keep him.
