Navigating the Canine Respiratory Outbreak: A Veterinarian's Guide for Pet Owners

By Paula Simons, DVM, DACVECC

In the past few weeks, an 'enigmatic' respiratory illness has been making waves in the canine community, leaving pet owners with questions and concerns. As veterinarians, our commitment to the health and well-being of your canine family members is unwavering. In this Q&A article, we'll delve into the mystery respiratory illness facing dogs, exploring its characteristics, potential causes, diagnostic processes, and what pet owners can do to protect their beloved companions.

What is the current landscape of the mystery respiratory illness affecting dogs, and how widespread is it?

The mystery respiratory illness has been causing heightened concern among veterinarians due to its sporadic occurrence and the challenge of pinpointing a specific causative agent. Reports from various regions indicate isolated cases and occasional clusters, making it difficult to determine the exact prevalence.

The clinical signs, which often include coughing, sneezing, nasal discharge, and lethargy, mimic those of other respiratory diseases.

How does this illness differ from more common respiratory conditions in dogs, such as kennel cough or canine influenza?

This respiratory illness shares similarities with common conditions like kennel cough (Canine Infectious Respiratory Disease Complex - CIRDC). There are many speculations of the etiology of the illness with consideration that it may be a viral agent - hence the poor response to antibiotics. Alternatively, the cause may be a bacteria that is not picked up by traditional diagnostic methods.

The challenge for veterinarians lies in distinguishing between the various respiratory diseases and tailoring treatment protocols accordingly.

What is not known is whether this disease is any more virulent than kennel cough or if media coverage has exemplified negative outcomes causing heightened alarm.

What are the typical signs of respiratory illness, and how can pet owners recognize them?

The signs of this respiratory illness closely mirror those of other respiratory conditions. Pet owners should be vigilant for signs such as:

  • Persistent coughing: The cough may be dry or productive
  • Sneezing and nasal discharge
  • Lethargy: A noticeable decrease in energy levels
  • Changes in appetite: Dogs may show a reduced interest in food
  • Labored breathing: most concerning when the dog is at rest

Intermittent coughing in an otherwise healthy dog does not warrant an emergency visit. However, pet owners need to seek veterinary attention if their dog demonstrates respiratory signs paired with trouble breathing, lethargy, decreased appetite, or any other abnormal behaviors.

What do veterinarians know about the potential causes or agents responsible for this mystery respiratory illness?

As of now, the exact causative agent or agents behind the respiratory illness remain unidentified. The complexity arises from the diversity of potential pathogens, including viruses, bacteria, and even environmental factors. Advanced diagnostic techniques, including molecular testing and viral cultures, are being employed to unravel the mystery. Collaborative efforts within the veterinary community, including research institutions and diagnostic laboratories, are ongoing to identify the specific agent(s) and understand the epidemiology of this illness. This illness may be caused by similar pathogens to CIRDC that are evading traditional diagnostic techniques. COVID is not suspected to be a causative agent at this time, but diagnostic laboratories are screening samples nonetheless.

How is the respiratory illness transmitted, and are certain environments more conducive to its spread?

Similar to other respiratory diseases, the illness is likely transmitted through respiratory secretions. Dogs in close proximity to one another, such as those in kennels, dog parks, or communal living situations, face an elevated risk of exposure.

Preventive measures, such as vaccination and hygiene practices, become even more crucial in the absence of a clear understanding of the transmission dynamics.

Is there a particular demographic of dogs more susceptible to the mystery respiratory illness?

At this point, there doesn't appear to be a specific demographic that is more susceptible to the respiratory illness. Dogs of all ages, breeds, and sizes have been affected, but young, old, and immunocompromised dogs may be more susceptible alongside brachycephalic dogs. As investigations continue, veterinarians are closely monitoring patterns and variations in the affected population to identify any predisposing factors.

What should pet owners do if they suspect their dog is showing signs of respiratory illness?

If a pet owner notices any signs of respiratory distress, such as persistent coughing, nasal discharge, or lethargy, it is crucial to seek prompt veterinary attention. Early intervention is key in managing respiratory diseases. Veterinarians will conduct a thorough examination, including diagnostic tests, to rule out other potential causes and tailor a treatment plan based on the observed signs.

Pet owners need to communicate any recent changes in the dog's environment, interactions, or potential exposures, as this information can aid veterinarians in the diagnostic process. It is important when you arrive at the veterinary hospital that you keep your dog in the car and call to check in. This will enable the staff to take proper precautions to help minimize the risk of transmitting the illness to other hospital patients.

How is the respiratory illness diagnosed, and what challenges do veterinarians face in identifying the causative agent?

Diagnosing a respiratory illness involves a combination of clinical assessment, laboratory testing, and, in some cases, advanced imaging. Veterinarians may conduct blood tests, nasal or throat swabs, and chest X-rays to gather comprehensive information about the dog's condition.

The primary challenge lies in the broad spectrum of potential pathogens and the lack of a standardized diagnostic test specific to this illness. Veterinary researchers are actively working on developing and refining diagnostic tools to streamline the identification process and enhance our understanding of the disease.

Can pet owners take any preventive measures to protect their dogs from the mystery respiratory illness?

While the outbreak of respiratory illness poses challenges in terms of prevention due to its unidentified nature, there are general measures that pet owners can adopt to minimize the risk of respiratory diseases:

  1. Vaccination: Ensure that your dog is up-to-date on core vaccinations, including those for common respiratory pathogens like parainfluenza, adenovirus, and distemper.
  2. Hygiene Practices: Practice good hygiene by regularly cleaning and disinfecting your dog's living environment, including bedding, toys, and food and water bowls.
  3. Limit Exposure: Avoid crowded environments, especially if there's an increased incidence of respiratory illnesses in your area. Consider forgoing trips to dog parks or communal areas during outbreaks. Try to avoid boarding or daycare if your pet is at high risk.
  4. Isolation: If your dog exhibits signs of respiratory illness, keep them isolated from other dogs to prevent potential transmission.
  5. Consultation with Veterinarian: Regular veterinary check-ups can help detect any underlying health issues early on, allowing for timely intervention and discussion of prevention.

It's crucial for pet owners to stay informed about the prevalence of respiratory diseases in their region and work closely with their veterinarians to implement appropriate preventive measures.

Are there any potential long-term effects or complications associated with the mystery respiratory illness?

The long-term effects of the mystery respiratory illness remain uncertain due to the ongoing nature of research and investigation. In many cases, prompt and appropriate treatment can lead to a complete recovery. However, as with any respiratory disease, there is a risk of complications, especially if the illness is not addressed early. There is always a low risk of mortality with any respiratory disease. It is not suspected that this disease is more virulent than others, but potentially there is more widespread media coverage of the illness - highlighting negative outcomes.

Pet owners should monitor their dogs closely during and after treatment, and any signs of worsening symptoms or complications should be reported to the veterinarian promptly.


The mystery respiratory illness facing dogs has added a layer of complexity to the already challenging landscape of canine health. As veterinarians, our commitment is to unravel the mysteries, provide the best possible care, and keep pet owners informed. Vigilance, prompt veterinary attention, and preventive measures are the cornerstones of protecting our beloved canine companions from the uncertainties of this respiratory enigma. By working collaboratively, the veterinary community and pet owners alike can contribute to the ongoing efforts to understand, manage, and ultimately conquer the challenges posed by this respiratory illness.
