Wow...both of mine have all black toenails. My girl looks like a standard yorkie and there is no way of telling by looking at her that she is a carrier. My male looks standard as well...but he does have a very small amount of white fur behind his ears...such a small amount that I have to be combing him in bright lighting to see it.
