The rescue I'm with saved 16 puppies. However, one right after the other started getting sick. We rushed them to the vet, some were positive for parvo, some weren't. The ones that weren't had to be separated and watched very closely. Unfortunately, we were all holding them and transporting them. It is a known fact that if you are holding a dog with parvo, the disease is on your clothes and shoes. Since they were being juggled, many got it. I'm not saying they all got it that day, b/c they were rescued all together. But I would make sure the clothes that were worn are washed in hot water and the shoes in bleach. Also, bleach the floors. It is highly contagious. Unfortunately, we lost 7 of the 16 babies.
