Can My Dog Get Parvo if Vaccinated?

Filed Under Dog Parvo Information | 5 Comments

Some dogs after they have received the Parvo vaccination still get the disease any way. The reason for this is that the virus has several different strains that seem to reinvent itself as soon as there is a vaccine for it. The veterinary community and physicians have been up to date on the changes and the effects of the vaccination on the virus and are doing as much as they can to educate themselves on the situation.

In particularly, most vaccines target only the 2a and 2b strains of the virus. The 2c strain was discovered as recently as 2006, and is far more aggressive and fast acting than other strains. Since most vaccinations do not target this version, a vaccinated dog can still get sick.

Bottom line: don’t assume that just because your puppy has been vaccinated, they are safe. It is still best to take the normal precautions to minimize the risk of catching the disease.

Parvo Virus, Spreading and Symptoms

Parvo virus is a highly contagious disease that is common among puppies under the age of 6 months. Some professionals believe that even after being vaccinated the disease still gets into the system of puppies, possibly due to the insufficient antibodies produced in the mother’s milk. The virus can be spread through fecal matter, vomit, and from insects, rodents and from bedding, dishes and the floor. The symptoms of Parvo are severe vomiting, diarrhea, fever, dehydration and bloody or dark feces.

Treatment and Prevention

The diagnosis of Parvo can only truly be done by a veterinarian, through a physical examination, blood test and examination of the animal’s fecal matter. Once detected the veterinarian will administer antibiotics, electrolytes, and a possible liquid diet for a while and a deworming agent. The bottom line for Parvo is that even after a dog is vaccinated it is possible for the animal to contract the disease. In most cases this does not happen but the best way to be safe is to have your pet tested and regularly tested and monitored on a regular basis, and if any unusual behavior occurs contact your veterinarian.

Natural solutions are also available that have had great success. Learn more about Parvo-K.


Parvo is a highly contagious disease commonly found in puppies but it has been seen on rare occasions in adult dogs. Keep pet belongings cleaned, bleached and sanitary. As well as keeping the pet well cleaned, taken care of and visiting the veterinarian on a regular, consistent basis. Also another thing to look out for is the type of breed of the dog will make it more prone to contacting the disease, so be aware of your dogs breed and characteristics. After a dog has been properly vaccinated it usually does not have an occurrence of the Parvo virus for the lifetime of the dog or at least for up to a year after the vaccination. Every dog adult and puppy reacts differently to vaccinations.

Many viruses develop and grow stronger over time, and the vaccines have to keep up with viruses and sometimes the vaccines are strong enough for the particular new strain of the virus and the animals suffer with the disease even after a vaccination, but it is up to the veterinarians to keep up on the latest changes and medical documentation to ensure that your pet lives a long and healthy life. Prevention and maintenance is key to having a healthy pet, as well as vigilance and perseverance to make sure that your veterinarian is aware of what is going on in the drug and medication world.

    My dog was over 1.5 years old, she was a very small figured dog, she had diarrhea for about 2 days and Friday she puked up her food. I started to worry but we waited, Saturday she was very sleepy but her stool had slowly gotten firmer. Sunday she began to drink water again, and Monday I woke up to her laying in a puddle of her own blood. We were at the vet within an hour but she was gone before 5pm. Parvo was something I never thought we would have to worry about because she had been vaccinated, not only that but because of her age. Always take the dog to the vet if you think it is parvo, I feel if we had taken her earlier she might of had a fighting chance.

    My four month old miniature poodle has parvo. Was off her food and throwing up then this morning there was bloody poo. She has been vaccinated. The vets say she has 50 50 chance of surviving.

    I work at a shelter and see Parvo a lot you can get you puppy Shots at 8 weeks and Parvo if not cleaned right can live on a surface for up to 2 years. You would need to clean your house with 1 part bleach to 2 parts water let it sit for 5mins then wipe up the bleach.
