Highly contagious parvovirus outbreak threatens Okanagan dogs

An outbreak of canine parvovirus in the Okanagan and Downtown Eastside of Vancouver has prompted a warning from the Humane Societies of BC, urging dog guardians to take immediate precautions.
The coalition of independent animal service nonprofits across the province made the announcement on Wednesday, June 10, stating that canine parvovirus, commonly known as “parvo,” is a highly contagious and potentially fatal viral disease that primarily affects puppies and unvaccinated dogs.
Chantelle Archambault with the Vancouver Humane Society said the virus attacks the intestinal tract and immune system, often causing severe illness that requires urgent veterinary treatment.
“Vaccination remains the single best way to protect dogs and prevent further spread within the community,” explained Archambault.
Now, the Humane Societies of BC are encouraging pet guardians to ensure their dogs are fully vaccinated by checking their records or reaching out to their veterinarian.
Romany Runnalls, the director of operations at the Okanagan Humane Society, said puppies require a series of vaccinations, typically beginning at six to eight weeks of age, while adult dogs should also stay up to date on vaccines.
“There is no direct cure for parvovirus, but early treatment can significantly improve survival rates. Supportive care, including IV fluids, medications, and hospitalization, can make a critical difference,” said Runnalls.
Common signs of parvovirus include lethargy, loss of appetite, vomiting, diarrhea (sometimes with blood), and fever. Dogs showing these symptoms, especially puppies or unvaccinated animals, should isolate all exposed animals and call their veterinarian immediately.
According to the Humane Societies of BC, the virus spreads through contact with infected feces or contaminated surfaces and can survive in the environment for months.
“Dogs do not need direct contact with an infected animal to become sick; exposure can occur simply by walking through a contaminated area,” stated the organization.
The Humane Societies of BC are responding to the outbreak through regional animal services. Low-income households can access emergency financial assistance for life-saving veterinary care for parvo through the Vancouver Humane Society’s McVitie Fund, province-wide, or vaccinations through the Okanagan Humane Society’s Pet Assistance Program if they are in the Okanagan region.
