Potty trained? Yorkies? What? lol, j/k. They can be the most difficult, Rizzo is 8 months now and when he is at my house he goes outside only, or on the pee pads if I am away. However when at my bf's place he seems to think rules don't apply. So, still working with him on that front, but for the most part he is coming along fine.
Good luck, and have patience, cause these little ones know how to test it
