You know, on YT someone referred to my Yorkies as being "so white" too. However, I have seen lots of Yorkies...some quite dark and some quite light. Brody's tan became a 'platinum blonde' then went more golden on his face. Mia lost all her black, went completely platinum blonde, then more golden all over.
Hi, and welcome to YT!
Your baby is beautiful!!! I wouldn't worry...
