Scooter is about 1 year old and of course I think he's beautiful, but I'm seeing silver, bluish gray colors developing on his shoulders. His body is black, his face and ears are a gorgeous caramel mixed with black and his legs and feet are the same pretty caramel but without the black. Is he supposed to get the change on his shoulders? He is my first Yorkie and since I know nothing about his background (he's a rescue) I'm wondering if he is pure Yorkie. Even if he's not, I adore him and think he's the most handsome guy I've ever seen.
