Boy are you lucky
a young Yorkie that is already pee pad trained
I don't know the percentage but a high number of Yorkie owners use this method. It is great in the wintertime when it is so cold and because you can never let your little one go outside by herself it helps year round
. They also have small bladders so if you have to be gone they are not going on your carpet.
Sounds to me that life is good for you
