do you wake up in the night at the time that he is pooing in the crate and immediately give attention of some sort (eg by telling him off or getting him out to clean up etc)?. If so i think that could positively reinforce it and teach him to do it for attention. And it might be worth trying ignoring it or moving his crate to another room.
otherwise - dogs wouldnt make the connection between pooing now and getting attention at a later time and its probably something else |
