Katie my 15 month old was just like that at 4.1/2 months when we got her. She's a beautiful blonde head now.
Suzi at 14 weeks is showing signs that she will have a blonde head too.
I'm told all Yorkie babies are black and tan to begin with, until they get their adult coats. I think it's lovely to watch them grow and guess how they will turn out.
