She looks like a Yorkie to me. My son's girlfriend has a yorkie just like her! He is very light but he is a yorkie. She got him from a vet friend The owners didn't want him because he had liver problems. They wanted to put him down and the vet said, NO WAY. He is only 3 yrs old! They did the surgery on him and then gave him to her once he was all good to go....
