Veterinary laboratories in several states including Illinois are investigating an unusual respiratory illness in dogs, and encouraging people to take basic precautions to keep their pets healthy as veterinarians try to pin down what’s making the animals sick.
Oregon, Colorado and New Hampshire are also among the states that have seen cases of the illness, which has caused lasting respiratory disease and pneumonia and does not respond to antibiotics. Symptoms of respiratory illness in dogs include coughing, sneezing, nasal or eye discharge and lethargy. Some cases of the pneumonia progress quickly, making dogs very sick within 24 to 36 hours.
The Oregon Department of Agriculture has documented more than 200 cases of the disease since mid-August. It has encouraged pet owners to contact their vet if their dog is sick and told state veterinarians to report cases as soon as possible. The agency is working with state researchers and the U.S. Department of Agriculture’s National Veterinary Services Laboratory to find out what is causing the illnesses.
Dogs have died, said Kurt Williams, director of the Oregon Veterinary Diagnostic Laboratory at Oregon State University. But without a clear way to define the disease or test for it, he said it’s hard to put a number on how many died from a severe form of the infection.
According to NBC News, researchers at the University of New Hampshire’s Veterinary Diagnosis Laboratory and the Hubbard Center for Genome Studies have identified a pathogen that might be what’s making pets sick.
Researchers told NBC News that a previously unidentified germ was detected in a genetic sequencing of samples from 30 dogs from New Hampshire who were infected last year and 40 dogs from Rhode Island and Massachusetts who were infected this year.
“It’s smaller than a normal bacterium in its size and in the size of its genome. Long story short, it’s a weird bacterium that can be tough to find and sequence,” said Dr. David Needle, pathology section chief at the College of Life Sciences and Agriculture at the University of New Hampshire.
Needle believes the germ likely evolved from a component of the dog microbiome.
Though the discovery of the germ is significant, veterinarians remain unsure if the same germ is what’s sickening dogs across the country.
Here’s what else we know about the illness, and what pet owners should watch for:
What is the illness?
The American Veterinary Medical Association said it is monitoring reports of a canine respiratory illness across the country.
In Oregon alone, more than 200 cases have already been reported from veterinarians since mid-August, but other cases have been reported in other U.S. states as well.
“Oregon Department of Agriculture (ODA) officials are working with state and national diagnostic laboratories to identify the causative pathogen, are asking veterinarians to report cases to the department as soon as possible, and advise dog owners to work with a veterinarian if their pet is ill,” the association told NBC Chicago in a statement. “The Colorado State University College of Veterinary Medicine and Biological Sciences says, ‘The possible virus, which is under intense observation by Colorado State University veterinarians, has been linked to cases of severe pneumonia and, tragically, resulted in some fatalities.'”
The AVMA said it’s not clear what’s causing the virus so far, but that is under investigation.
Labs across the country have been sharing their findings as they try to pinpoint the culprit.
David Needle, senior veterinary pathologist at the University of New Hampshire’s New Hampshire Veterinary Diagnostic Laboratory, has been investigating the mysterious disease for almost a year.
Dogs have died, said Kurt Williams, director of the Oregon Veterinary Diagnostic Laboratory at Oregon State University. But without a clear way to define the disease or test for it, he said it’s hard to put a number on how many died from a severe form of the infection.
What symptoms should dog owners watch for?
In addition to coughing, sneezing, discharge from the eyes or nose, trouble breathing and fatigue have also been observed, according to the Oregon Department of Agriculture. Dogs who exhibit symptoms may also test negative for common causes of respiratory illnesses.
Dog owners who observe any of the above symptoms are advised to take their dog to a vet immediately.
The AVMA said cases have primarily fallen into “three general clinical syndromes,” including:
- Chronic mild-moderate tracheobronchitis with a prolonged duration (6-8 weeks or longer) that is minimally or not responsive to antibiotics.
- Chronic pneumonia that is minimally or not responsive to antibiotics.
- Acute pneumonia that rapidly becomes severe and often leads to poor outcomes in as little as 24-36 hours.
Where have cases been reported so far?
TODAY reports that veterinarians in the following states are confirmed to have observed cases that match the description of strep zoo:
- Oregon
- Colorado
- New Hampshire
- Rhode Island
- Massachusetts
- California
- Indiana
- Illinois
- Washington
- Idaho
- Georgia
- Florida
Needle’s lab and colleagues at the university’s Hubbard Center for Genome Research have looked at samples from dogs in Rhode Island, New Hampshire and Massachusetts and more will be coming from Oregon, Colorado and possibly other states.
What can you do to prevent it?
While vets encourage dog owners to keep their furry friends away from places where other dogs are likely to be, it is stressed that dogs in need of veterinary care are seen as soon as symptoms are shown.
Vets also advise owners to ensure that their dogs are up to date with necessary vaccinations.

Dog owners are advised to contact their veterinarian ahead of exposing their dogs to an environment with multiple other dogs.
Needle said his team has not seen a large increase in dogs dying from the illness but still encouraged pet owners to “decrease contact with other dogs.”
Though dog owners are advised to be careful, experts also clarify that owners should use caution rather than worry, offering the following tips to help protect dogs from respiratory illnesses:
- Reducing contact with large numbers of unknown dogs. Just like with other respiratory pathogens, the more contacts your dog has, the greater the risk of encountering a dog that’s infectious.
- Reducing contact with sick dogs. This can be harder to determine but if a dog looks sick (coughing, runny nose, runny eyes), keep your dog away from it.
- Keep sick dogs at home and seek veterinary care.
- Avoid communal water bowls shared by multiple dogs.
- Ask your veterinarian for advice on which vaccinations your dog should have. Common vaccinations include canine influenza, Bordetella and parainfluenza.
- If it’s sick, consider having your dog tested with a PCR test to help determine the causative agent (viral/bacterial), if possible.
Williams had a simple message for dog owners: “Don’t panic.” He also said dog owners should make sure that their pets are up to date on vaccines, including those that protect against various respiratory illnesses.
