Wilson loves a tasty backyard scooby snack, he's my little Turd Burglar. Sorry I'm no help as I tried everything under the sun, even did an ice cream vs poop test one time, he preferred the poop (seriously google Poop v. Peppermint Ice Cream) and it'll come up. As disgusting as it is for some dogs they simply like it. What's disgusting and nasty to us is not to them unfortunately. After 5 years, Wilson will still have a backyard sample. I just get in his mouth with a wet paper towel and clean him out. His favorites turds are the ones in the snow. I feed all 4 of mine the same food too, Fromm Beef Fritatta.
