dogs are just that disgusting
i've heard a few answers to this. my puppy used to eat the older dog's poop, and still will, occasionally. a vet told us that if you put adolf's meat tenderizer on the older dog's food, it will make the poop undesirable! haha..but it worked. If your dog is eating strange dog poop, you won't have access to their food, so the other thing to try is giving your dog some banana every other day. apparently he may be lacking some vitamin that he gets from the other dogs feces.
