Do you use potty pads in the house? With Rosie, we started out leaving her in the bathroom, then she moved into the bedroom and bathroom, and when she was trained she had free run of the house. This was when we were not home. And it helped with accidents in the house. When we were at home, I took her out consistently. When she would potty, she got a treat. To this day, she will not pee in the house.
. It worked well with her. However I will tell you, it was almost a year old before she was fully trained.
As far as your other pup, maybe someone here has experience with moving and yorkies. I have never moved with my girls. Good luck with potty training!
