Parvovirus in Dogs

CPV or canine parvovirus is one of the most contagious and deadly viral infections in puppies. It is a DNA virus, commonly infecting young and non-vaccinated dogs. The virus is spread either through direct contact with an infected pup, or indirect contact with a contaminated object. This relentless virus usually effects the bone marrow, intestinal tract and lymphopoietic tissues. So, how does a pet owner identify parvovirus and what steps need to be taken for treatment, and future prevention?

Puppies under five months and dogs who have never been vaccinated are at greatest risk for infection.

Is Parvo Airborne?

While the parvo virus is highly contagious, it is not airborne. Most commonly, this viral disease is spread through the feces of contaminated dogs, or through something the infected pup has come in contact with. The virus can easily be found on the floor, clothing or other inanimate objects. The fur and paws of dogs can also carry the virus if they have been in contact with any infected surfaces.

Symptoms & Diagnosis

Dogs infected by canine parvovirus start to show symptoms within 5 to 7 days of infection. Some primary signs of infection include lethargy, lack of appetite, and mild fever. As the viral life cycle progresses, dogs suffer from vomiting and severe, often bloody, diarrhea which can lead to rapid dehydration, damage to internal organs and cause septic shock. If your pup shows signs related to parvo, contact your veterinarian immediately.

There are several tests to diagnose parvo according to the ASPCA. These include:

Fecal ELISA: enzyme linked immunosuppressant assay
PCR: polymerase chain reaction
CBC: complete blood count evaluation

Fecal CPA ELISA antigen tests are the most popular test choice of veterinarians. A fecal swab is performed and results are returned within 10-15 minutes. A PCR test is also used with a fecal sample, however a definitive diagnosis takes more time to attain. CBC tests are used to measure the level of white blood cells to determine if an infection is present. This test does take longer as blood cultures likely have to be sent to an outsourced lab, taking up valuable time to initiate treatment for the virus.

Treatment of Parvovirus

Unfortunately, there is no cure for parvovirus infection in dogs, nor anti-viral treatment. The only way we can help our pets is to support them so that the body can fight off the infection on its own. According to the ASPCA, supportive care usually includes:

Antibiotics– used to combat secondary septic infections
Fluid Therapy– counteract dehydration with electrolyte crystalloid solution
Pain Control– by use of injectable morphine for abdominal pain
Nutritional Support– easily digestible, low-fat foods are recommended
Control of Vomiting/Diarrhea– anti-nausea and stomach protectants are important

The best treatment for a dog with parvovirus is a broad spectrum antibiotic. The most common antibiotics used include ampicillin, cephalexin, and flouroquinolones.

How to Prevent Parvovirus Infection

Vaccination is the only way to prevent parvo infection. A combination vaccine like DHPP, DAPP, DA2PP and DHLPP are administered to protect pups against the virus. It is one of the core vaccines which is given in every 3 to 4 weeks until the age of 16 weeks. Make sure the boosters are timed appropriately and avoid taking your dog to public places until he/she is fully vaccinated.

If you are a member of our Pin Paws Plus or Pin Paws Pet Care programs, you have access to whiskerDocs (24/7 pet Telehealth). Pet parents that suspect their pet may be infected with the virus can speak to a veterinarian for advice, prior to scheduling a visit to the ER vet or routine clinic and receive education on when further intervention is necessary.
