Answer
That is very unusual, Sandy. I would take her and the surviving pup to the vet ASAP. She could have an infection or something that is keeping her from producing milk, and the vets can give the puppy fluids and milk to help keep it alive if it's struggling. When the puppies are first born, the mother should have produced milk that is called colostrum, which is filled with antibodies to help keep the puppies from getting diseases like parvo. After the first day, regular milk should begin to 'flow.'

I would seriously consider having her spayed if I were you.
