Parvovirus Cases Rising in Maine: What Dog Owners Need to Know

Dog owners in parts of Maine are being urged to take extra precautions after multiple cases of a dangerous canine virus were confirmed.

The Houlton Police Department reported several confirmed cases of canine parvovirus in the area, while the Eastern Maine Emergency Veterinary Clinic in Brewer says the Bangor region is also seeing a spike in infections.

Parvovirus, according to WGME, is highly contagious, can survive harsh Maine winters and may linger in environments such as dog parks for weeks or even months. If left untreated, or treated too late, the virus can be fatal, especially for puppies.

According to the American Veterinary Medical Association (AVMA), parvovirus attacks a dog’s white blood cells and gastrointestinal tract, and in puppies, it can also damage the heart. The virus spreads through direct contact with infected dogs, their feces, or contaminated surfaces like kennels, food, and water bowls.

Officials strongly advise that dogs not up to date on vaccinations—or those who haven’t completed a full vaccine series—should avoid dog parks and other high-traffic dog areas. Dog owners are encouraged to contact their veterinarian to ensure vaccinations are current.

If a dog shows symptoms such as vomiting, diarrhea, or extreme lethargy, it should be quarantined from other dogs immediately and receive prompt veterinary care.

So while the risk for most Maine dogs remains moderately low, it is definitely worth keeping an eye on your dogs and double-checking to make sure they are up-to-date on all the shots and vaccines that they require to stay as healthy as possible.
