My sister made a comment about my Yorkie....she is still a pup, so her colors will change. Right now is she black and tan like normal Yorkie pups, but her left paw is white, she has some white on her chest, and a little dribble of white on the back of her neck. I have never seen a Yorkie pup in any picture with any white o them. This is why I picked her to begin with because she was different then the other two that were in the litter. I saw the mom and the dad both, and they were great. My sister's concern was that maybe she wasn't pure bred. I believe she is - even if she wasn't, it wouldn't change anything anyways!
