This is what actually worked when Suzi was a puppy . She did the exact same thing . Than we started placing the poo, w/o touching it/yuck on the pad... Suzi really caught on fast where to poop

YAY! It did not take long at all for her to poo on her pads after the poo was there ! I guess Yorkies are visual learners! It worked like a charm. Try it a few times, and see if it works for your pups. Also, it is important to have more then one pee pad down. Place it where your puppy is going most of the time .
