This is only my opinion... .I do not think it is right just to breed a Yorkie for the sake of keeping her babies. Many have already said she is too small, and i am thinking that you want a tiny yorkie .
This is not in the best interest of your dog, or the Yorkie breed . 4lbs is very tiny for an adult female. Breeding and prenancy is very difficult on a little dog.
I personally do not feel it is the right thing to do . your jepardizing the health of your female Yorkie, and stressing her out and her body.
