The Chosen One

This is Harry, he is a 1.5yr old Shih Tzu. Harry cannot refrain from pooping in his cage almost every single day (even if only left in there for 2 hours for a grocery run and is put out to go potty). We've used cage dividers when they were little pups to help this acclimate to being crate trained, but Harry never caught on, but his fraternal brother Murphy did and doesn't poop his cage unless he really has to. Sometimes Harry will just sit outside and not go potty even when trying to reinforce with a treat after he goes potty.
Do you fellows have any suggestions? I am at my last straw and am tired of coming home to the filthy smell and its causes me much stress as it is VERY frustrating and brings out the worst of moods...
