It is likely that your puppies will get infected also if the mother is not yet over the infective stage of the disease. There is also a possibility that a high fever can end the pregnancy. I am sorry. I cannot think of a way to protect the puppies as they are in contact with body fluids when being born. A pregnant dog can pass the distemper virus to her unborn puppies via the placenta. An infected dog or puppy can continue to shed the distemper virus for many months.
