She looks like a full blooded, pure,unmixed, adorable yorkie to me. I think so many people are attracted to this precious breed, that they are unaware of the different sizes, and shades of black, grey, white and gold that these little characters come in. Yorkie coat colors change very much in their young years, some faster than others. Your baby looks like she will have a very beautiful silver coat; but don't be surprized if it changes again!! Enjoy her, she looks like you got a good one
