Outbreaks of an unknown canine respiratory illness have been becoming increasingly prevalent as noted in the media over the past few months in many states across the United States. Especially this time of year, increased respiratory infections are reported among dogs, but this particular one doesn鈥檛 yet have a name 鈥� or a clear cause or treatment.
Owners are reporting symptoms that mainly include prolonged coughing, lethargy, and change in appetite. We spoke to American Kennel Club Chief Veterinarian Dr. Jerry Klein about what we know so far, and what dog owners should do to stay vigilant.
Symptoms to Look Out For
Dogs that are being treated for what is believed to be the same respiratory illness have symptoms that include coughing, significant lethargy, and a change in appetite. 鈥淚f you see those together, that would warrant seeing a veterinarian,鈥� says Dr. Klein.
鈥淚 would advise owners not to panic when their dog coughs, but to contact their veterinarian at the first sign of a cough and see what they recommend and voice their concerns,鈥� Dr. Klein says. 鈥淐ertainly visit a veterinarian or visit an emergency clinic if a cough is lingering, changes character, and doesn鈥檛 seem to go away, or if the dog becomes lethargic or goes off feed.鈥�
These symptoms could also be the cause of other upper respiratory illnesses in dogs, like kennel cough, pneumonia, and canine influenza.
What We Know About This Canine Respiratory Illness
The American Veterinary Medical Association in August 2023 in the Portland metro area of Oregon. From mid-August to mid-November, more than 200 cases of this illness were reported. National numbers are not known exactly because states have different reporting requirements, but have been found in Colorado, New Hampshire, and Oregon. Reuters recently reported that have been found in California, Florida, Georgia, Illinois, Indiana, Maryland, Massachusetts, Rhode Island, Vermont, and Washington.
Dr. Klein says that because the cause is unknown, tracking the illness is also more difficult. 鈥淲e don鈥檛 know if the outbreaks that were experienced in Oregon, for example, are the same cause or causes of the dogs that were studied in New Hampshire.鈥�
But it鈥檚 not as widespread as people may think. 鈥淚 don鈥檛 think cases are as prevalent all around the country,鈥� he says. Dr. Klein mentions that only two dogs had been brought in at the practice that he works at in Chicago with similar symptoms in the past few weeks, and these cases turned out to be Bordetella. 鈥淭here may be other areas that may be worse, and certain parts of the country that may be experiencing outbreaks of something.鈥�
In some cases, pneumonia has been reported in relation to this illness. 鈥淭he dogs that got pneumonia were a little bit different than typical pneumonia cases that vets see,鈥� Dr. Klein says. 鈥淏ut it doesn鈥檛 give us an idea of what it is.鈥�
Is Unknown Canine Respiratory Illness Contagious?
Unfortunately, at the moment, there is no certain answer on whether or not this illness is contagious between dogs.
鈥淲e can鈥檛 be 100% certain on the exact means of contagion, the duration in the environment, and things like that,鈥� Dr. Klein says. 鈥淲hether it鈥檚 a virus or bacteria, and how exactly it鈥檚 spread, we don鈥檛 know exactly.鈥� Until researchers know more, Dr. Klein says that vets are taking extra precautions to keep dogs that are showing symptoms isolated.
Dr. Klein does say that it does appear to be contagious dog-to-dog. 鈥淲e haven鈥檛 seen it in people or in cats relating to this, so we think it鈥檚 species-specific.鈥� That being said, he emphasizes that it鈥檚 still not known how it transfers, or how it can pass between dogs in the same household, kennels, etc.
Looking For Answers Through Research
When a dog is brought in with coughing or similar symptoms, Dr. Klein says that vets have been trying to do diagnostic tests and respiratory panels when they can to rule out other known illnesses. Across the country, researchers are trying to piece together the common symptoms and potential causes to nail down whether this is something that is known, like a variant of kennel cough, a new illness entirely, or possibly multiple causes.
鈥淛ust like with humans, we have flu-like symptoms, and we go to urgent care to test for COVID, or Influenza, because these signs mimic each other,鈥� says Dr. Klein. It is also still unknown whether or not this illness is viral or bacterial.
鈥淯nfortunately in this case, the answers haven鈥檛 been as instant as anyone would like,鈥� Dr. Klein says. 鈥淰eterinarians want to do the best thing for the dog. We want to be able to know what we鈥檙e treating and how to treat it properly.鈥�
What Should You Do if You Suspect Your Dog is Sick?
If your dog has a lingering cough, owners should call and consult their vets. There might be procedures already put in place to sanitize rooms and keep offices less full so that the illness isn鈥檛 passed to other dogs in waiting rooms. In the case that this illness is contagious, Dr. Klein says it鈥檚 important to limit exposure to other dogs. 鈥淲e don鈥檛 want to hurt other dogs if this is very contagious,鈥� he says. 鈥淲e don鈥檛 know how it is, so we have to go along the lines that it could be very contagious.鈥�
In the case where these symptoms do arise, Dr. Klein says to bring your dog to the vet or emergency room. Your veterinarian can help identify and rule out other causes by running diagnostics tests, and treat anything that is identifiable in the meantime, as well as symptomatic care.
If you鈥檙e worried about the number of cases in your area, Dr. Klein urges owners to consult their veterinary offices to see if there have been cases in the area. The best people who will know of outbreaks around you will be your local vet or emergency veterinarian. 鈥淏e aware of what鈥檚 going on at your local level, and ask if they鈥檝e seen a recent upsurge of respiratory cases,鈥� he said. 鈥淚f they have then your area may be experiencing an outbreak of something, and you should be especially prudent about how and where you handle your dog among other dogs.鈥�
What Can You Do to Help Prevent Your Dog From Getting Sick?
Dr. Klein says that part of the rising levels of panic have to do with the unknown illness being called a 鈥渕ystery illness.鈥� 鈥淲e don鈥檛 know if there鈥檚 a cause or multiple causes leading to the pronouncement of people saying their dogs are sick,鈥� he says. 鈥淎nd there鈥檚 no way of knowing unless proper diagnostic tests are taken and ruled in, or ruled out, to figure out if this is one of those quote unknown cases or one of the many known cases.鈥�
But there are still things that you can do to keep your dog safe and stay aware of the situation. 鈥淏e preemptive and keep your dog as healthy as possible,鈥� he says. 鈥淢ake sure that your dogs are up to date on all the things that we can vaccinate for that can cause illness.鈥�
Dr. Klein also advises trying to maintain your dog鈥檚 hygiene. Dogs should not be sharing water bowls, and food and water bowls should be frequently disinfected. He also advises washing crates often, and making sure spaces that your dog inhabits have good ventilation. 鈥淭here鈥檚 no guarantee, but it鈥檚 the best thing we can do to try to help minimize possible occurrence of things,鈥� Dr. Klein says. 鈥淲e can鈥檛 control the world and the environment completely, we can only control what we can.鈥� He says to make sure to wash your hands thoroughly and frequently, especially after handling any new or unknown dogs.
As more research is released on this illness, it鈥檚 important to stay informed, from a local level as well as a national level. 鈥淭his may be something else, but we want to protect our dogs even in the best case scenario,鈥� Dr. Klein says.
