I really don't know the answer to that. But my second Yorkie which I rescued from a puppy mill didn't have much hair. Was very thin and never grew. I wasn't sure why. I just assumed that it might have been her living environment and such. But when I was looking for my recent Yorkie I did ask the breeders when inquiring if the pups had much hair. I explained why I was asking and they told me that every once in a while the mother would "throw" a pup with that type of hair. Maybe the veteran Yorkie owners will better be able to answer your question. |
