CANINE PARVOVIRUS (CPV) - White Ocean Vet Clinic

What is CPV and how is it Transmitted?


Parvovirus causes vomiting and diarrhea in dogs and is one of the major infections that dogs pick up in Vietnam. The severity and survival rate of the disease is variable. Dogs which do survive can suffer long-term consequences such as chronic diarrhea and heart disease. The virus attacks quickly growing tissues so pups less than 6 months are especially susceptible. Infection occurs through contact with contaminated feces which is why it is a common problem in pet-shops. Incubation time (from encountering the virus to developing the disease) is 2-14 days.

Infected dogs excrete the virus in their feces for approximately 2 weeks post infection. The virus can remain in the environment for years.

What are the Signs of CPV ?


  • Gastro-intestinal: Causes hemorrhagic enteritis (diarrhea with blood) together with vomiting and dehydration, so can lead to septic / endotoxic shock and death.
  • Cardiovascular: Myocarditis (inflammation of the heat muscle) can show as sudden death.

Presentation: Sudden onset of bloody diarrhea / vomit, decreased appetite, lethargy and fever. Some puppies may collapse with the gastric signs27-02-03

How is it Treated ?

Based on controlling the symptoms. The goals are to mollify the intestinal tract, restore and maintain the fluid-electrolyte balance and resolve shock, sepsis and endotoxaemia.

Treatment regimens include fluid therapy, anti-vomiting and anti-diarrheal drugs, antibiotics and drugs which control endotoxaemia and shock.

The cardiac form often causes sudden death and is not treatable.

How is it Prevented ?

The risk is reduced by vaccination but NOT eliminated. Vaccination can be started from 6 weeks of age. 2-3 vaccines are normally required (depending on age/breed) followed by annual boosters.

Some breeds are more susceptible (Rottweiler, Doberman, Spaniel) to parvovirus infection and in these cases the vet may recommend a follow up vaccine for puppies at around 5 months of age.

Vaccines cannot be given to dogs already suffering from the disease.
