Quick summary:

• Parvovirus is a highly contagious and potentially fatal disease in dogs
• Vaccination is the best way to prevent infection
• Early veterinary care greatly improves survival
• The virus spreads easily and can live in the environment for a long time
• Extra precautions are needed if you have multiple pets at home

What is parvovirus?

Canine parvovirus (often called “parvo”) is a serious viral disease that affects dogs, especially puppies and unvaccinated animals. It attacks the intestines and immune system, leading to severe illness that can become life-threatening without treatment.

There have recently been reports of a parvo outbreak in Vancouver, particularly in the Downtown Eastside. This makes prevention and early action especially important for local pet owners.

How is parvo spread?

Parvo spreads through contact with infected feces, contaminated surfaces, or even indirectly on shoes, clothing, or hands. The virus is very hardy and can survive in the environment for months.

Dogs do not need direct contact with a sick dog to become infected. Simply walking through a contaminated area can be enough.

Best way to prevent parvo: Vaccination

Vaccination is the most effective way to protect your dog.

Puppies require a series of vaccines, typically starting at 6 to 8 weeks of age and continuing every few weeks until they are fully protected. Adult dogs also need to stay up to date on their vaccines.

If you are unsure of your dog’s vaccine status, contact your veterinarian to set up an appointment.

If you suspect parvo

Parvo is a medical emergency. Early treatment significantly improves the chances of survival.

If you suspect your dog may have parvo:

How is parvo treated?

There is no direct cure for the virus itself, so treatment focuses on supporting the dog while their body fights the infection.

Most dogs with parvo require hospitalization, where treatment may include:

• Intravenous fluids to prevent dehydration
• Medications to control vomiting and nausea
• Antibiotics to prevent secondary infections
• Pain management and supportive care
• Nutritional support as the dog begins to recover

Treatment can be intensive, especially in severe cases, but many dogs can recover with prompt and appropriate care. Early intervention is one of the most important factors in improving survival.

What to do if you have other pets at home

If one dog in your household is diagnosed with parvo, it is important to protect other animals:

• Isolate the sick dog from other pets
• Avoid sharing food bowls, bedding, or toys
• Wash hands thoroughly after handling the sick animal
• Clean and disinfect surfaces regularly (parvo is resistant to many common cleaners; bleach-based products are typically required)
• Speak with your veterinarian about vaccination for other dogs in the home

Even after recovery, the virus can remain in the environment, so ongoing caution is needed.
