Can a Dog Get the Parvo Virus Twice?

Can a dog get parvo twice? We will answer that question today. In case you are not familiar with parvo, it’s a contagious disease caused by the canine parvovirus.

It commonly occurs in pups since their immune system isn’t fully developed yet. While occurrences are lower, it can also happen to adult dogs if they haven’t been vaccinated with the parvovirus vaccine.

Know How the Parvovirus Works

Experts classify parvo as a disease of the stomach or small intestines because these are the parts of the body where the virus does the most damage. It commonly disrupts the function of the small intestines, inhibiting the absorption of the right nutrients from food. In young pups, it can also affect the bone marrow, lymphopoietic tissues, and even the heart.

It’s important to take note that most parvo mortalities occur within 48 to 72 hours following the emergence of its symptoms: weakness, loss of appetite, abdominal pain and bloating, either a low or high body temperature, vomiting, diarrhea (sometimes bloody in severe cases). Yes, it can be fatal so it’s important to keep a watchful eye out for the symptoms mentioned.

The parvovirus is spread through direct contact with an infected dog or a contaminated object. It can also be transmitted through contaminated feces, the environment, and even people. It’s challenging to eradicate this virus because it is resistant to heat, cold, humidity, and drying. It can even survive in the environment for long periods of time.

Is There a Cure for Parvo?

Dogs who are infected with the parvovirus can be cured, but you, as the pet owner, have to get your pet to the hospital on time. Know that there isn’t a specific drug that can kill the canine parvovirus. What your vet will do is focus on supportive measures, helping the body get stronger to the point where it can fight the infection all on its own.

For example, if your dog has a fever, then the vet will focus on giving medication to lower down his temperature. If diarrhea and vomiting are present, the animal doctor will start an IV line to replenish the fluids already lost, preventing dehydration. Don’t worry because the prognosis is good as long as the necessary measures are done on time.

As they say, prevention is better than a cure so it’s best to avoid the whole infection incident by having your pup vaccinated. The first dose can be given when the pup reaches six to eight weeks old. The succeeding doses between fourteen and sixteen weeks of age.

Is It Possible For My Dog to Get Parvo Twice Even After Vaccination?

Now, on to the question of your dog getting parvo twice. Yes, it’s possible but highly unlikely because he already has the antibodies he needs to be immune to the disease. However, he can still infect other dogs within two weeks, after being discharged from the hospital. You’ll need to isolate your dog within this time to protect your other pets or other dogs in your neighborhood.

It’s a similar case with vaccinated dogs. It can occur. The parvovirus has many strains, after all, and it can evolve (just like the common cold) but the chances are slim. It will generally depend on your dog’s overall health, so be a responsible pet owner and make sure that your dog is fed, clean and happy.

In case you’re wondering, it’s best not to get a second dog after your first one has been exposed to the virus. If you have a yard that your first dog always plays in, it’s likely that your second dog will get the virus there unless he is fully vaccinated before entering your property.
