I have 3 other diferent breeds of Dogs, and I remember when I took them to the Vet, that was one of my questions. It is something we are all curious about, in general. With Yorkies, if you pay more money, because the person selling them charged more because they were going to be smaller and they end up twice as big as expected, you can see her frustration. She loves her dog, she is just upset that she was mislead. I would say that most of us don't like being lied to and I think that was her point.
