Parvovirus is found in any environment (lawns, homes, kennels, dog parks, etc.). It comes from infected dogs that excrete the virus in their vomit or feces. Parvovirus is very hardy outside its host, can survive winter conditions, and is resistant to common household cleaners.

How do dogs get parvo in the first place?

Parvo in puppies is caused by the canine parvovirus. This virus is highly contagious and spreads through direct contact with an infected dog or by indirect contact with a contaminated object. Your puppy is exposed to the parvovirus every time he sniffs, licks, or consumes infected feces.

How is parvo started?

Dogs that are ill from canine parvovirus infection are often said to have "parvo." The virus affects dogs' gastrointestinal tracts and is spread by direct dog-to-dog contact and contact with contaminated feces (stool), environments, or people.
