I took your advice and emailed Dr Dodds. She actually CALLED instead of emailing back. What a nice person she is. Anyway she said that with the pup being immunosuppressed by Prednisone, I do NOT want to vaccinate the other pups, with fear they could shed the parvo virus and infect my little man. His last dose was just shy of 8 weeks, she advised to wait for everyone's vaccines til 9 weeks.
