Im ROFL at this!
When my Cali was at a Service Dog school one of the main things they spend a great deal of time on was distraction issues. I had not had her very long before she left for Service Dog School and the trainers there had very little experience with small dogs, but the thing they kept telling me was that when I went out there for my part of the handler training they had never seen such a focused pup. She never took her eyes off me the whole training time.
That was 8 year ago - And when we go for her every 3 to 5 year assessment, that focus is always commented on. Since they had not trained many Yorkie’s the behavior assessors say they have never seen another like her. I just say it is Yorkie behavior!
Enjoy you baby, and you do get used to not going to the bathroom alone
