I think what she is asking is actually about the "papers" for the puppies. And this is only my opinion, but as long as you are selling them to be pets and not to be bred I really don't think the papers are that important. China is lucky to have found you and it really sounds like you are loving and caring for her and her puppies. I dont see any reason why you shouldn't keep & raise her and her puppy. Good luck in whatever you decide.
