Yes, they all did. But only Ashley was hit really hard with it. Most of them were only sick for a day or so, with some relapsing later for another day or so. One person who has two of them says she isn't sure her pups had parvo. They had some of the symptoms but not all and they weren't very bad off. She had them vaccinated last Sunday and they are being spayed today. Another foster has two of them and they both had parvo. One had it much later than the other. Neither one was too bad off. She is tentatively vaccinating tomorrow and spaying/neutering next Friday. One pup was with a different foster but she is currently on vacation. The pup had parvo, got better, and then relapsed several days later. I haven't heard much detail about that one. The pup is being watched by one of the other fosters until her person gets back home, so I don't know what her schedule is. UPDATE: I just found out the ones being spayed today had to postpone a week. They have snotty noses. Hmmmm. Vaccinated too early? Mine also had runny noses but they are over them now.
