My Chico has white white hair too and I love how it looks. From his picture you can tell a little bit and the rest of his body is light light grey. Some black remains from when he was a tiny baby though on the tips. I think he will be a very light colored yorkie than the ones I have seen with black or red and he is a full yorkie. My husband compares his hair to an old persons hair.
Still cute as a botton to me!
