This is a very bad situation for everyone. It is so sad that the pups have to be taken from their mother at such a young age. Try posting on Petfinder. How about a few signs at the vets in your area. This is a very bad time to sell puppies. People buy dogs for xmas gifts and after the holidays, many of these gift end up in shelters.

Best of luck to you and your mom. You are good people for trying to help out.
