When I started working with NILIF with my girl I always got 'gushy' with the praise and it didn't take her very long to quit going belly-up. Do you get a happy voice and body when he does well? that might help. Rosie still does the peeing for new people but she has gotten way too much confidence with those of us she knows. She is pretty good now though but she was just tied in a yard so probably not as abused as a lot of dogs.
