Let me say again 12-14 weeks was not possible for me with me working full time. Again i done this out of kindness because the girl that had her did not want to deal with the puppies. I spoke with many breeders for advice on when to let the puppies go, there was a lot of different opinions on that issue.. Everyone believes differently. Thank you for the advice so far and I will plan to let the mother handle the weaning of the puppy that will be staying.
