You can try the canned or frozen pineapple too. Just make sure you thaw out the frozen first. My vet told me to use meat tenderizer, but it has so much salt in it I don't feel comfortable doing it. Max has been eating pineapple regularly for almost a month and still eats his poop. The only thing I can do is potty train him to go outside. If he poops outside he doesn't eat it. We are trying very hard to get him trained!
