I would be very concerned they all have parvovirus. This is a life threatening infection of unvaccinated puppies and dogs, and it causing them to vomit, have diarrhea, and be extremely. It's also very deadly. The best way to prevent this is to make sure the mom and dad are up to date on their vaccines, the puppies have zero contact with any other dogs, and the environment is thoroughly cleaned as parvo can live in the home for a long time. Unfortunately, if the mother isn't up to date on her vaccines, it may be too late to vaccinate her. It's typically not recommended to vaccinate a pregnant dog due to risks to the unborn puppies, but it may be able to be done in cases where the dog does not have immunity to a specific disease and needs to be immunized. In those cases, a killed vaccine should be used. I would speak to your vet to see if they feel it's safe to vaccinate the mom if she isn't up to date on her vaccines.
