This is a current pic....five months old?  I'm no expert, but she looks like she could be a red-leg yorkie, to me.  Is her coat soft and silky to the touch, or wirey?
 
Hopefully someone will happen on this thread that can address the issue better than I, but if not, do a search on it....there was a recent discussion. 
She's a CUTIE, by the way!   Welcome!
