My little guy eats not only his poop but also my other two yorkies poop as well. I've tried the pineapple and something else my vet told me to put in his food but nothing works. The vet said it won't hurt him its just gross. He knows he is not suppose to eat it because if I'm in the room he'll wait until I'm not looking. The key is to pick it up quick!!!!! That's not easy when you have three (soon to be four) dogs.
