Welcome to YT!! I have to tell you that I have had Yorkies for 20 years and I have never had one that is 100% potty trained, 100% of the time!! I have had some that are better than others but they are not like a big dog that would rather hold it and blow up than go in the house!! I have one Yorkie that used to "fake" squat when we would go outside, she would squat and look like she was peeing but if you picked her up, her privates would be dry and she wanted to just come in the house quick so she could pee inside!!! They are very smart and I think sometimes vindictive!! But they are sooooo cute and loving that I put up with it!! Good luck, maybe someone has a magical training method that they can teach both of us, because crate training never did work for me with Yorkies.
