Can A Dog Get Parvo More Than Once


Parvo, a highly contagious and deadly virus that attacks the gastrointestinal tract of dogs, is a serious concern for dog owners. The symptoms of parvo are severe and include diarrhea, vomiting, lethargy, loss of appetite, and dehydration. Despite being vaccinated against the virus, many dog owners wonder if their furry friends can get parvo more than once. In this article, we will answer the question “can a dog get parvo more than once?” and provide you with all the necessary information to keep your pooch safe.

Understanding Parvo:

Before we dive into the topic at hand, let’s understand what parvo is and how it affects dogs. Parvovirus is a highly contagious virus that spreads through contact with infected feces or vomit. The virus attacks rapidly dividing cells in the body, particularly the lining of the intestines and bone marrow. This leads to severe damage to the gastrointestinal tract and a weakened immune system, making it difficult for dogs to fight off other infections.

Symptoms of Parvo:

The first signs of parvo usually appear within 3-10 days after exposure. The symptoms of parvo include:

1. Diarrhea: It is often bloody and foul-smelling.

2. Vomiting: Dogs may vomit frequently and have difficulty keeping down food or water.

3. Lethargy: They may become weak, tired, and uninterested in activities they usually enjoy.

4. Loss of appetite: Dogs may stop eating or drinking altogether.

5. Dehydration: They may become severely dehydrated due to vomiting and diarrhea.

6. Fever: Dogs may develop a high fever as their body tries to fight off the infection.

Can A Dog Get Parvo More Than Once?

Now that we understand what parvo is let’s answer the question at hand – Can a dog get parvo more than once? The short answer is yes; a dog can get parvo more than once. However, it is relatively rare for dogs to contract the virus twice.

Why Is It Rare For Dogs To Get Parvo More Than Once?

Parvo infection provides lifetime immunity in most cases. When a dog is infected with parvo, its immune system produces antibodies that protect against future infections. These antibodies remain in the dog’s system and provide lifelong immunity to the virus.

However, there are instances where dogs may not develop complete immunity after contracting parvo. In such cases, they may be susceptible to reinfection. Additionally, puppies under six months of age and dogs with compromised immune systems are at a higher risk of getting parvo again.

How Can You Prevent Parvo Reinfection?

Preventing parvo reinfection involves taking necessary precautions to keep your dog safe and healthy. Here are some tips to prevent parvo reinfection:

1. Vaccination: The best way to prevent parvo infection is through vaccination. Puppies should receive their first vaccine dose between 6-8 weeks of age and continue with booster shots until they are 16 weeks old. Adult dogs should receive a booster shot every three years or as recommended by their vet.

2. Proper Hygiene: Parvovirus spreads through contact with infected feces or vomit, so proper hygiene is crucial. Always pick up after your dog, disinfect contaminated areas thoroughly, and wash your hands regularly.

3. Avoid High-Risk Areas: Avoid taking your dog to high-risk areas such as dog parks, kennels, or animal shelters unless they are fully vaccinated.

4. Maintain Good Health: A healthy dog has a better chance of fighting off infections than an unhealthy one. Make sure your dog receives regular check-ups from a vet and stays up-to-date on vaccinations.


In conclusion, while it is possible for dogs to get parvo more than once, it is relatively rare due to the immunity provided by previous infections. However, it is essential to take necessary precautions to prevent parvo reinfection and keep your furry friend safe and healthy. By following the tips mentioned above and staying vigilant, you can ensure that your dog stays protected against this deadly virus. Remember, prevention is always better than cure!
