In the fine tradition of how not to do something, my Yorkie at 4 will not poop on a mat and has lost much of her housebreaking. We have two other dogs and life was fine until about 3 years ago our whole family went through great stress. Missy seems to have absorbed the remainders. while the other dogs are adjusting she wants to do right and will walk right up to the pad cross over and pee. any help/
