I was not at all familiar with Yorkies until my daughter met one at a friends & told me about him. She knew I wanted a dog, and he was very sweet.
So I started researching the breed and it seemed like everything every where said how they are "sassy, confident, prissy, smart...." and I knew she was going to be super spoiled so we named her Princess.
My daughter picked her middle name "Adelle" though we have never used it.
The nickname I gave her is "Puppy!" I never realized I was then one day I said it & she turned right around. Now when I want her to come find me in the house I say "Where's my puppy!?" and she comes running!
