When it's time to see a vet
The disease can kill a dog quite quickly (sometimes in a matter of days), and it may leave surviving animals with intestinal and heart damage. So if you see symptoms or even suspect parvo, get to your vet immediately. The only way to know if a dog has parvovirus is through a diagnostic test.

However, the best time to see the vet about parvo is when you get your puppy vaccinated. That's the best thing you can do to prevent this killer of puppies from ever entering your life.

When your puppy's most vulnerable
The timing of protecting your puppy can be a little tricky. The mild and temporary immunities that the mother passes on to her pups actually interfere with the vaccine's effectiveness--but exactly when those maternal antibodies fade varies from dog to dog, depending on factors such as nutrition, medical history, and even breed. It's that window of vulnerability--the time after the mother's immunity has faded, and before the vaccine has kicked in--when puppies catch this ever-present virus.

That's why puppy vaccines have to come in at least two stages, and why it's vitally important that you don't skip that second visit to the vet. It's also important to not let your dog walk on the ground where infected dogs may have been until the vaccine has fully kicked in--ask your vet when it's safe to take your pup out and about.

What's next
Treatment generally means a lengthy and expensive hospital stay, with at least five to seven days in intensive care, rehydration through an IV, lots of antibiotics, and medications to control nausea. Even then the prognosis isn't good. Many severely infected animals die, even with the best available care. Without the correct amount of properly balanced intravenous fluids, their chance of recovery is very small. Beating parvo is a difficult challenge, even for the toughest of puppies.
