Kennel Cough: What You Need to Know

Our dogs fill our lives with joy, loyalty, and constant companionship. As devoted pet parents, their health and well-being are always a top priority. So, when they’re not feeling their best, it can be deeply concerning.

One common illness that many dog owners face is kennel cough—a contagious respiratory condition that can leave even the liveliest dogs feeling under the weather. The good news? With the right knowledge, kennel cough is manageable and, in many cases, preventable.

Here’s everything you need to know to recognise, treat, and help protect your pup from this uncomfortable illness.

What Is Kennel Cough?

Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory infection that can affect dogs of any age or breed. It causes inflammation in the trachea and bronchi, leading to a distinctive, dry cough that often sounds like a goose honk. While typically mild in healthy dogs, kennel cough can pose more serious risks for puppies, senior dogs, or those with weakened immune systems.

Causes And How It Spreads

Kennel cough is caused by a combination of viruses and bacteria that target a dog’s respiratory system. The most common culprits include Bordetella bronchiseptica, canine parainfluenza virus, and canine adenovirus type 2. These pathogens weaken the protective lining of the respiratory tract, making dogs more vulnerable to secondary infections.

The infection spreads quickly in places where dogs are in close quarters—such as kennels, doggy daycare centers, grooming salons, and animal shelters. However, isolated cases can occur anywhere, not just in group environments.

Kennel cough is primarily transmitted through airborne droplets released when an infected dog coughs or sneezes. It can also spread through direct contact, like sniffing or licking, and by sharing contaminated items like water bowls, toys, or bedding. Because the pathogens can linger on surfaces, the risk of exposure in communal areas is especially high.

My Dog Doesn’t Leave The Property – Is He Still At Risk?

It’s a common belief that dogs who stay at home and don’t socialise are safe from kennel cough—but unfortunately, that’s not entirely true.

Kennel cough is highly contagious and can spread through airborne droplets, contaminated surfaces, and even on your clothing or hands. If you come into contact with an infected dog—at the park, a friend’s house, or even a vet clinic—you could unknowingly bring the germs home with you.

So yes, even dogs who never leave the property can still be exposed. That’s why awareness and prevention are important, no matter your dog’s lifestyle.

How to Tell If Your Dog Has Kennel Cough

The most noticeable sign of kennel cough is a persistent, dry cough that often sounds like a goose honk. This cough may get worse when your dog is excited or active.

Other common symptoms include:

• Retching or gagging (sometimes mistaken for choking)
• Sneezing
• Runny nose or nasal discharge
• Low energy or lethargy
• Reduced appetite
• Mild fever

In most healthy dogs, symptoms improve on their own within one to three weeks. However, if your dog shows signs of laboured breathing, extreme fatigue, or symptoms that persist or worsen, it’s important to contact your veterinarian right away.

When to Call the Vet

If you suspect your dog has kennel cough, a visit to the vet is often the best first step—especially if symptoms don’t improve within a few days. Diagnosis typically involves a review of your dog’s recent exposure to other dogs and a physical exam. Your vet may gently press on your dog’s trachea to trigger the characteristic cough.

In more serious cases, or if complications like pneumonia are suspected, further testing—such as chest X-rays or bacterial cultures—may be necessary.

You should contact your vet right away if:

• The cough lasts more than a few days
• Your dog shows signs of difficulty breathing or extreme fatigue
• Appetite decreases or your dog refuses food
• Symptoms worsen despite rest and home care

Prompt veterinary care ensures your dog gets the right treatment and helps prevent more serious health issues.

Treatment and Management

In mild cases of kennel cough, most dogs recover with rest and supportive care at home. It’s important to keep your dog calm and limit physical activity, as exertion can aggravate their irritated airways. Make sure they have access to fresh, filtered water to stay hydrated and support the healing process. Running a humidifier nearby can also help ease breathing and soothe their respiratory tract.

For more severe cases, your veterinarian may prescribe antibiotics to treat or prevent secondary bacterial infections. Cough suppressants (antitussives) might also be recommended to reduce persistent coughing and make your dog more comfortable.

While hospitalisation is rarely needed for kennel cough alone, it may be necessary if your dog is struggling to breathe or develops complications like pneumonia. Early intervention ensures the best possible outcome and helps prevent the illness from worsening.

Preventing Kennel Cough

Vaccination is one of the best ways to protect your dog from kennel cough. While no vaccine can guarantee full immunity—since multiple viruses and bacteria can cause the illness—it significantly reduces the risk of infection and the severity of symptoms if your dog does get sick.

Practicing good hygiene is also key. Clean your dog’s food and water bowls, bedding, and toys regularly to limit exposure to harmful germs. If you’ve interacted with another dog, especially one that appears unwell, wash your hands before handling your own pet.

To further lower the risk, try to avoid high-risk environments like crowded kennels or poorly ventilated spaces, especially if your dog is young, older, or has a weakened immune system.

Who’s Most at Risk?

While kennel cough can affect any dog, some are more prone to serious complications due to weaker immune systems.

Puppies are especially vulnerable because their immune systems are still developing, making it harder for them to fight off infections. Senior dogs also face higher risks, as aging naturally weakens their immune defenses.

Additionally, dogs with chronic health conditions or those undergoing treatments like chemotherapy may have compromised immunity and require extra precautions to stay safe.

If your dog falls into any of these categories, talk to your veterinarian about the best ways to protect them—especially if they’re in environments where exposure is more likely.

Natural Remedies for Support

In addition to veterinary care, some natural remedies may help ease symptoms and support your dog’s recovery from kennel cough.

Honey is a popular option thanks to its natural anti-inflammatory and soothing properties. In small amounts, it can help calm an irritated throat—but it should never be given to puppies under one year old.
Coconut oil, when added sparingly to meals, may offer immune-boosting benefits.
Chamomile tea is known for its calming and anti-inflammatory effects. Once cooled, a small amount can be offered to your dog to help soothe their system.

Always consult your veterinarian before introducing any home remedies, especially if your dog has underlying health conditions. Even natural treatments should be used in moderation and with professional guidance to ensure safety and effectiveness.

Conclusion

While kennel cough may sound concerning, it’s typically manageable with the right knowledge and care. By understanding its causes, recognising the symptoms, and knowing how to treat and prevent it, you can confidently protect your dog from unnecessary discomfort—and support a quicker, smoother recovery. Being informed is one of the best ways to keep your furry companion happy, healthy, and safe.
