There's been a recent rash of breathless e-mail about the "new" C2 strain of Parvo, and how deadly it is, how only a few vaccines will work on it, and so on. Very scary!
The sky really isn't about to cave in:
The "new" parvo is seven years old, current vaccines work, and so long as your dog has current immunizations, and you follow proper hygene, you're in pretty good shape.
Go play fetch with your pup, or something.
