I have no idea why they do that.. But no worries. I have a Shiba Inu and when she was a pup, she would eat her poo all the time! :lol: She never got sick though. And it did gross me out! :sad3: You can try goin to Petsmart or something and get this spray called Bitter Apple and spray it on the poo once it comes out. But I know you can't catch him when he goes all the time. Or when you do, just pick up the poo and discard it right away. :wave:
