I wouldn't worry to much yet as the poor boy has just been taken away from his family and put into probably a very busy noicy house then taken to a very busy noicy vet that wants to do some indignaties to him. Firm solid rules and expectations will keep him in line he is still a baby but needs rules that will be the rest of his life. biting nipping whining are not acceptable.
Poor little guy don't baby him yet don't expect him to understand it all in a weekend either
