I get your question! I would think that if you mix a traditional Yorkie and a pure Biewer, there could be a variation in the colors of the pups. So if someone had such a pup mix, it may not be representative of all the color possibilities?
Perhaps pics of the whole litter might give some idea of the color possibilities?
If you have one or get one, it would be interesting to see what he or she turns out like.
