We've never caught him going poop in his crate, just when he's crying to get out because "someone made a big stinky in here!". Then we don't scold him or even respond to it. We take him out to his potty area and then clean up the crate mess, put him back in and go back to sleep. Whenever he goes potty (either poop or pee) we tell him to "hurry up and what a good boy he is" while he's going and then tell him what a good boy he is afterwards just like the books have recommended. When we've caught him going pee inside the house, we've clapped our hands and said "NO!" then immediately taken him outside to his area and told him what a good boy he is as soon as he goes.
