Update, 8/24/22: Additional testing has revealed the illness impacting dogs in Michigan’s northern Lower Peninsula to be canine parvovirus. The affected dogs did not have a history of complete vaccination. Even though the dogs were displaying symptoms of parvovirus, they were testing negative on the tests; more sensitive diagnostic tests were done in a laboratory to confirm parvo.

Original post follows; the recommendations below are still strongly encouraged.

We’ve recently heard of media reporting on dogs in northern Michigan coming down with a parvo-like illness. Details are very scarce at this point, but Michigan State University’s Veterinary Diagnostic Laboratory has the most up-to-date info we know of. Their recommendations as of August 22, 2022:

  • Make sure your dog is up to date on vaccines, especially if you’ll be traveling with pets to the northern Lower Peninsula
  • Have dogs/puppies fully vaccinated before interacting with other animals
  • Be sure to clean up after your pet when you’re walking them out in public, and don’t allow your dog to come into contact with other animals’ waste
  • If dogs or puppies show signs of illness, keep them at home and away from other dogs and contact your veterinarian

Though the disease is common in Michigan, canine parvovirus cannot be spread to people or other domesticated animal species.
