Yes. Obedience training. Instead of handling your dog physically (pulling him off your niece, nudging him to move and pushing him out the door) teach him the commands "off" and "outside" so he can move his body instead of you. If he is in control of his body, he'll be MUCH less likely to pee. Be patient. Since he grew out of it with dogs, he'll probably grow out of it with people, too. But you must learn to respect his physical space and tell him what to do instead of physically moving him.Is there a method to working with submissive peeing?
