I would maybe call around to the local vets and even some that aren't local but are close. Parvo is something you DO NOT want your family pet to get. It is a very nasty disease that eats them away from the inside out. Not to mention, it is EXTREMELY expensive to treat.

The other bad thing, if you bought a house that was previously owned and the previous owners dog had parvo...if they didn't bleach their backyard, the disease is still alive back there.

I haven't heard of any going around, but I would definitely make some phone calls.
