I had the same problem with my boy yorkie. I tried to use one of those trays to help keep the pad from not moving and it didn't work....he just tore it apart. I am not sure how he did it, he is was only 4 pounds at the time. I ended up tucking the pad under the back door mat and he never messed with it. Then I eventually trained him to go outside. Is your yorkie a puppy? It took mine until he was 1 1/2 to stop messing with the pee pee pad. Good Luck!
