No they are supposed to get the Parvo shot more than just once in their lifetime. If I'm not mistaken, they get it once a year. Someone please correct me if I'm wrong about that. But I am CERTAIN they get it more than once, just not sure how often. This is something you DEFINATELY need to get! One of our members just lost her little girl to Parvo unexpectedly.
I would hate for this to happen to someone else.
