At first, make him understand he is your dog - and no one elses, you feed him, take him out for his "jobs" and play with him.
How are you supposed to make it "your dog?" With a wife who loves the new puppy, and kids who adore dogs, are you supposed to keep them away? I can understand training sessions with you and the dog alone, but are you saying the family can't enjoy the pup too?
