Parvovirus causes severe life-threatening illness, through dehydration, acid-base imbalance, infection and shock. If you suspect your pet may be infected, it is an emergency and you should contact your veterinarian immediately. Parvo is carried by dogs. Adult dogs may be infected carriers and not show signs. Dogs with the typical symptoms and diarrhea shed the virus perhaps for as long as 7 days after the symptoms have ended. Generally, it takes 3 to 10 days from the time of exposure for symptoms to appear and for your dog or pup to test positive. The onset of clinical signs is usually sudden, within 12 hours, or even less. The Parvovirus is particularly long-lived in the environment, lasting anywhere from 1 to 7 months, or even a year. Due to the large amounts of virus particles shed in the feces of an infected dog and the ability of the virus to survive, complete eradication of the virus is often impossible.
Parvo may be brought home to your pup on shoes, hands, and even your vehicle tires. Even if your dog or pup does not leave your yard, they may get this disease if precautions aren’t taken.
