This is BYB. You should be getting this poor dog in for an abort and spay before it is too late.

You have mixed breeds. You had not researched; don't know or seem to care WHAT the standard if for the breed. No testing, no concerns about what genetically may turn out wrong with puppies. I agree wit the above, if you and grandma wanted puppies, go to a shelter. Now go take care of your dear Nena while you can.
