I have a different vet for Rocky than I use for
Sheba and Pepper.
When Rocky was a puppy , he liked going to the vet until
the day he got neutered.
After that he hated his vet and the male staff their.
Sooo last year, I finally switched vets for him.
I think dogs have a very good memory when it
comes to a bad experience and they recognize smells etc.
Not saying your vet abused your dog, but possibly something
happened that tramatized her?

Just a possible thought.
