Parvovirus is more common in puppies but the virus also infects older dogs. What is more alarming is that the clinical symptoms may not be apparent in older dogs. Other types of parvovirus have existed for decades but canine parvovirus is a newcomer having been around only since the 1970s.
Parvovirus is extremely contagious and can be transmitted by any person, animal or object that comes in contact with an infected dog's feces. Highly resistant, the virus can live in the environment for months, and may survive on inanimate objects such as food bowls, shoes, clothes, carpet and floors.
