Just try to keep your new mom isolated from the rest, after dealing with your other dogs, be sure and wash your hands before dealing with her. If you have a lab coat, wear it with the others. It can be managed but it is not fun.
Just as a note, new puppies with KC don't cough, they sort of "gurgle", you can feel it when they are picked up. As already mentioned, the danger with KC is a secondary infection. Once the 1st pup comes down with it, all need to go on antibiotics.
