Vets are like human doctors -- not every doctor is good for all things. I had a good internist who completely missed my severe thyroid problem. It took a trauma surgeon to diagnose me, and then I was off to the endocrinologist.
There is a YT member here whose girl had her problems diagnosed by a dermatologist.
I believe a specialist or a vet with more experience with yorkies will help you get to the bottom of your girl's problems.
