How Fast Can Parvo Spread?

Parvo is a virus and is very contagious.  It is spread via a fecal-oral route.  Infected feces contaminate the environment and thus spread.  Parvo virus is a very hardy virus that can live in the environment--yard, house, for several years.  Once exposed signs usually develop within 3-10 days.  This is a preventable disease--have your dogs, especially puppies and young adults vaccinated.  Puppies need several parvo vaccines during development and an unvaccinated adult dog should be given a series of two boosters.
