Nothing worked for us except time and changing food brands when Ruby was eating HER OWN poop. Pineapple did nothing, I learned she loves HOT sauce, and I don't think meat tenderizer did anything either. But switching brands of food changed the chemistry, I think.... I almost
took her back to the pound over that - it's disgusting esp when I was napping on the couch and she'd come in to give me a fresh, stinky kiss! Aargh! Yea, I admit to chasing Ruby around the yard with a broom and screaming 'don't eat that' !!!
