We are fortunate in that Scooby has never done that, but then we don't give him the opportunity as we pick up immediately after he has been potty. I know this isn't always possible for the working moms so I guess finding the remedy in food or addatives is the only way. I often wonder why dogs do this, I have heard that it is a lack in enzymes that can cause it. I know when Scooby was little he used to seek out the rabbits poop in the yard, but that all stopped when we put the fence up.
