My Visa's nephew, Jasper, developed parvo after reciving his parvo shot. When he was returned to my cobreeder for a "vaccine reaction," he was exposed to my dog and her littermates. They were fine until they recieved their parvo shot, which weakened their immune systems, and they developed parvo too. My dog was the first to get sick at 4 weeks of age. This is why I do not believe in maternal antibodies -- I've heard too many cases of young puppies catching viruses. My dog's mother had her parvo vaccination that year and titered well six months before the litter. Yet the entire litter caught parvo at 4-5 weeks of age. Also, parvo tests are not accurate! The puppies in the litter that tested negative for parvo were the ones that died, even though they were treated for parvo and seperated from the other puppies.

Just keep vigilant -- clean everything! All you can do is hope and pray. It's a terrible virus but it's getting easier to treat with everything we know today. Don't worry about your dog's catching the parvo. If they've had their shots theyr are fine. Even so, after a year of age, most dogs are immune to parvo. Parvo is one vaccine that "sheds" itself from the dog after it's been given -- so dogs in contact with dogs who've just recieved a vaccine, or places that dog has been, is already exposed to the disease, and thus building an immune to it.
