I have two yorkies, and my second one had my first actually back track. He was trained to use the potty pad, but when he came here he wouldn't use the potty pad at all, but after we kept putting him outside with my little girl he learned to go outside. We still have accidents in the house, but now I am only cleaning up after him instead of the pair of them. Its just gonna take time to get them trained. You may need to lock your new baby in a certain area of the house where the potty pad is kept until it gets the idea, while letting it out for constant play. I locked both of mine up (they had the bedroom, laundry room, and bathroom to roam) for just three days and now my little man is doing so much better. Good luck!
