I'm sorry your little dog is suffering. I've never taken mine anywhere except for nail trimming and the last time I did that the kid made three of them bleed and I was even holding her for him. My son and I do it now as she really fights us but I don't have to leave her with a stranger who may have less aptitude than I have.
This woman is a groomer and several people have said they liked her grooming tape:
