Gina, I don't have any advice, just empathy. We have biting yorkies, too. Chase, 10 year old male, will bite unpredictably. Sometimes he wants to be picked up, you pick him up and he growls and nipps. Sometimes I'm sitting on the couch and go to get up, he's at my feet is startled and bites me on the ankle. When I brush him near his head, he will turn and bite me, and yes, he has drawn blood. I've told people that if yorkies were bigger dogs, we couldn't have them because of the biting. They are so small, they may draw blood, but can't really hurt you too much.

Even my little 3 year old, 4 lb Zoe, will bite me when I'm brushing her near her head, or when I'm bathing her and washing around her eyes. I just have to be stern with her and let her know who is boss.

Chase bites so randomly, I don't know the solution. He's just an agressive dog.

Both are neutered/spayed, so if the behavior is genetic, it won't be passed on.

Sorry this happened to you. Defending things in their mouths is instinct. It's sad that she was so very defensive that she bit you.
