I know she is not really a yorkie. but she thinks she is.She is in so much pain right now

I was up with her from 2:30 on. She was whining and couldn't put any weight on her back right leg. she is now at the vet. I took her first thing this am. My poor sweet golden girl tore her ACL!!!She'll need surgery

I'm sitting at work and and all I want to do is cry. I go to pick her up at 3 and I find out when surgery will be then. I'm so scared and worried for her.... Please keep her in your prayers.
