If your dog has ever developed a sudden, harsh cough that sounds like honking or gagging, they might have caught kennel cough. As temperatures drop, this cough becomes more common—much like how colds spread more easily among people during the winter months. At The Barking Birch, we sometimes hear from concerned pet parents whose dogs get sick shortly after their stays, especially if their pup isn’t around other dogs often. While this can feel discouraging, it’s extremely common and usually goes away on its own.
What Is Kennel Cough?
Kennel cough, medically known as canine infectious respiratory disease (CIRD) or infectious tracheobronchitis, is a highly contagious respiratory infection in dogs. It affects the trachea (windpipe) and bronchial tubes, leading to inflammation and persistent coughing.
Kennel cough can be caused by several bacteria and viruses, most commonly Bordetella bronchiseptica, often combined with viruses such as canine parainfluenza or adenovirus.
Why Kennel Cough Increases in Winter
Kennel cough tends to ramp up during colder months for several reasons:
- Dogs spend more time indoors with closer contact
- Ventilation may be reduced
- Viruses and bacteria survive longer in cooler conditions
- Daycares, boarding, and grooming facilities are busier during holidays
Why Infrequent Daycare Guests May Be More Vulnerable
Dogs that don’t regularly interact with other dogs are more susceptible to kennel cough when they return to social settings. Just like children returning to school after a long break, dogs coming back into group environments are suddenly exposed to more germs than they’ve encountered in months.
While dogs don’t develop immunity in the same way humans do with repeated exposure, regular social exposure helps their immune systems stay engaged and responsive. Dogs who are rarely around other dogs may not have the same level of immune readiness, making them more vulnerable when they re-enter a group setting.
Common Kennel Cough Symptoms
Keep an eye out for:
- A dry, hacking cough (often described as “honking”)
- Gagging or retching, sometimes with white foam
- Sneezing or nasal discharge
- Mild lethargy
Most dogs feel otherwise normal and continue eating, drinking, and playing as usual.
Is Kennel Cough Contagious?
Yes! Kennel cough is highly contagious, which is why even well-maintained facilities can see cases, especially during peak seasons. If your pup is coughing, it’s important to limit contact with other dogs until cleared by your veterinarian. Kennel cough can spread before showing symptoms, which is why transparency and quick communication are important.
How Kennel Cough Is Typically Treated
Most mild cases resolve on their own within 1–3 weeks. Treatment may include:
- Rest and reduced activity
- Cough suppressants prescribed by a veterinarian
- Antibiotics in certain cases
Contact your veterinarian if your dog:
- Has a cough lasting longer than a few days
- Shows signs of lethargy, fever, or loss of appetite
- Is a puppy, senior, or has underlying health conditions
- Develops worsening symptoms or labored breathing
Early care helps prevent rare complications such as pneumonia.
How You Can Reduce Your Pup’s Risk
While kennel cough can’t be fully eliminated, you can lower your dog’s risk by:
- Keeping vaccinations (including Bordetella) up to date
- Maintaining consistent daycare attendance rather than long gaps
- Avoiding daycare if your dog shows any respiratory symptoms
- Supporting immune health with good nutrition and routine vet care
Consistency helps dogs adjust more smoothly to social environments.
Final Thoughts
Kennel cough is frustrating and unfortunately hard to avoid, especially for social dogs. But, with consistent social activity, up-to-date vaccinations, and good communication, you can keep your pup as happy and healthy as possible throughout their doggy daycare vacations.
