If a vaccinated dog comes into contact with a dog that is sick and actively shedding parvovirus, it would not be unreasonable to booster the vaccine early. While not impossible, it is very unlikely that a dog that has recovered from canine parvovirus would get it again.
However, this does not mean that your dog does not need to be vaccinated against canine parvovirus if he or she has recovered from it in the past. Routine vaccinations should still be performed. Home Diseases A-Z.

Submit Feedback. No specific drug is available that will kill the virus in infected dogs, and treatment is intended to support the dog's body systems until the dog's immune system can fight off the viral infection.
Treatment should be started immediately and consists primarily of intensive care efforts to combat dehydration by replacing electrolyte, protein and fluid losses, controlling vomiting and diarrhea, and preventing secondary infections.
Sick dogs should be kept warm and receive good nursing care. When a dog develops parvo, treatment can be very expensive, and the dog may die despite aggressive treatment. Early recognition and aggressive treatment are very important in successful outcomes. Since parvovirus is highly contagious, isolation of infected dogs is necessary to minimize spread of infection. Proper cleaning and disinfection of contaminated kennels and other areas where infected dogs are or have been housed is essential to control the spread of parvovirus.
The virus is not easily killed, so consult your veterinarian for specific guidance on cleaning and disinfecting agents. Young puppies are very susceptible to infection, particularly because the natural immunity provided in their mothers' milk may wear off before the puppies' own immune systems are mature enough to fight off infection. If a puppy is exposed to canine parvovirus during this gap in protection, it may become ill.
An additional concern is that immunity provided by a mother's milk may interfere with an effective response to vaccination.
This means even vaccinated puppies may occasionally be infected by parvovirus and develop disease. To reduce gaps in protection and provide the best protection against parvovirus during the first few months of life, a series of puppy vaccinations are administered.
Puppies should receive a dose of canine parvovirus vaccine between 14 and 16 weeks of age, regardless of how many doses they received earlier, to develop adequate protection. To protect their adult dogs, pet owners should be sure that their dog's parvovirus vaccination is up-to-date.
There are a variety of risk factors for Parvo, but the virus is most commonly transmitted either by direct contact with an infected dog, or indirectly, by the fecal-oral route. There is evidence that the virus can live in ground soil for up to a year.
Goals of parvo treatment include keeping the pet hydrated, controlling nausea and vomiting, preventing secondary bacterial infections and controlling abdominal pain. Hospitalization is needed so medications and fluids can be given through injections. Parvo pets have a very difficult time keeping oral medications, food and water down so successful home treatment is extremely difficult to achieve. Pets can be hospitalized up to 7 days in some cases but in most cases days. It invades the body of its host, attacks the cells and begins replicating itself.
First, it attacks the lymph nodes in the throat and then travels to the bloodstream, bone marrow and intestines. By educating yourself on the symptoms and warning signs of this virus, you can help your pet to get on the road to recovery as soon as possible.
Parvovirus is most commonly spread through dog feces. An infected dog will shed the virus in his feces three to four days after exposure, before he shows any symptoms himself. An ounce of feces from an infected dog contains 30 billion to 35 billion units of the virus.
One billion units are enough to trigger infection. If a healthy dog comes into contact with infected feces or vomit, he can contract the disease. Parvovirus is so prolific it affects most of the environment, including the air and soil.
