Hello and welcome to Petco Pet Education Center, formerly Petcoach. Dogs can shed the virus for up to 14 days after they have clinically resolved the infection. The other problem with the parvo-virus is that it is very hearty, meaning that it can survive a very long time in the environment. It can survive freezing and high temperatures, therefore if you had a dog in your yard with parvo-virus, then any dog that comes into your yard for years later is at risk. Therefore you have to be very carefully with new puppies in your yard/house after having a dog with parvo. Make sure all animals are fully vaccinated. Best of luck with your little one!
