Dewey is a rescue that came to us at 3 years old and we quickly found out he ate his own poop. Every. SINGLE. Day. We tried to break him of it to no avail. He is 10 now and has a habit of licking his legs which makes him smell like fecal matter. My son made him a shame hat out of a tuna can. I think Dewey feels some shame…..but as he ate his own poop as usual this morning… so maybe not.
