Kennel Cough in Dogs: Symptoms, Causes, Treatment, and Prevention

Kennel cough, also known as canine infectious tracheobronchitis, is a common respiratory illness that affects dogs of all ages and breeds. While the name might sound alarming, kennel cough is usually mild and treatable. However, in certain cases—especially in puppies, senior dogs, or those with weakened immune systems—it can lead to more serious complications.

If you’ve ever boarded your dog, visited a dog park, or enrolled in group training classes, you’ve probably heard about kennel cough. Understanding what it is, how it spreads, and how to protect your dog can give you peace of mind and help keep your furry friend healthy.

 

What Is Kennel Cough?

Kennel cough is an upper respiratory infection in dogs, similar to the common cold in humans. It is typically caused by a combination of viruses and bacteria, the most notable being Bordetella bronchiseptica. Other contributors include canine parainfluenza virus, canine adenovirus, and canine coronavirus.

The condition gets its name because it spreads quickly in places where dogs are housed close together, such as boarding kennels, shelters, and doggy daycares. However, dogs can contract kennel cough anywhere dogs gather, including dog parks, grooming salons, or even during a walk around the neighborhood.

 

How Kennel Cough Spreads

Kennel cough is highly contagious and primarily spreads through airborne droplets released when an infected dog coughs, sneezes, or barks. Dogs can also catch it through direct contact (sniffing or licking another dog) or by touching contaminated surfaces like water bowls, toys, or bedding.

Because the illness spreads so easily, outbreaks are common in environments with large groups of dogs. This is why many boarding facilities and daycares require proof of a kennel cough vaccine before accepting dogs.

 

Symptoms of Kennel Cough

The most recognizable symptom of kennel cough is a loud, hacking cough that often sounds like your dog is trying to clear their throat or honking like a goose. Other symptoms may include:

• Dry, persistent cough (sometimes triggered by exercise or excitement)
• Retching or gagging, sometimes followed by white foam
• Sneezing or nasal discharge
• Runny eyes
• Mild fever
• Lethargy
• Loss of appetite in more severe cases

In most cases, dogs remain active and otherwise appear healthy despite the persistent cough. However, if symptoms worsen or progress to pneumonia, you may notice labored breathing, significant lethargy, or loss of appetite—signs that require immediate veterinary attention.

 

Diagnosing Kennel Cough

If you suspect your dog has kennel cough, take them to the veterinarian for a proper diagnosis. Your vet will review your dog’s medical history, perform a physical exam, and may listen to their lungs with a stethoscope.

In mild cases, additional testing is usually unnecessary. However, in more severe cases—or if pneumonia is suspected—your vet may recommend blood work, X-rays, or lab tests to identify the exact pathogen.

 

Treatment for Kennel Cough

Treatment depends on the severity of the illness. Most healthy adult dogs recover from kennel cough within one to three weeks with rest and supportive care. Common treatment options include:

• Rest and Home Care: Limit strenuous activity, provide a warm and comfortable environment, and keep your dog hydrated.
• Cough Suppressants: Prescribed by your vet to ease persistent coughing.
• Antibiotics: Used if a bacterial infection such as Bordetella is identified or if secondary infections develop.
• Anti-Inflammatories: To reduce discomfort and throat irritation.

During recovery, avoid exposing your dog to other dogs to prevent spreading the illness.

 

Complications of Kennel Cough

While kennel cough is usually mild, complications can arise in puppies, senior dogs, or dogs with underlying health issues. The biggest risk is pneumonia, which can be life-threatening if untreated. Signs of complications include:

• Severe lethargy
• High fever
• Loss of appetite
• Difficulty breathing

If you notice these symptoms, seek veterinary care immediately.

 

Preventing Kennel Cough

Prevention is key, especially if your dog regularly interacts with other dogs. Here are the best ways to protect your pet:

1. Vaccination
   The Bordetella vaccine is the most common preventive measure against kennel cough. It can be given as an injection, nasal spray, or oral vaccine. Many boarding kennels and daycares require proof of this vaccine, which typically needs to be boosted every 6–12 months.
2. Avoid High-Risk Environments During Outbreaks
   If you hear of a kennel cough outbreak in your area, limit your dog’s exposure to busy dog parks, kennels, or grooming salons until it’s under control.
3. Good Hygiene Practices
   Wash your hands after handling other dogs, disinfect bowls and toys, and keep your dog’s living space clean to reduce the spread of pathogens.
4. Strengthen Your Dog’s Immune System
   Proper nutrition, regular exercise, and routine vet visits all contribute to a healthy immune system that can fight off infections more effectively.

 

When to See a Vet

You should consult your veterinarian if:

• Your dog’s cough lasts more than 10 days
• They develop nasal discharge or fever
• They stop eating or drinking
• They seem unusually tired or weak

Even if the illness appears mild, a vet visit can help confirm the diagnosis and provide peace of mind.

 

Final Thoughts

Kennel cough is a common, highly contagious illness, but it is rarely serious in otherwise healthy dogs. With proper care, most dogs recover quickly and without complications. The best way to protect your pet is through vaccination, responsible socialization, and early veterinary care when symptoms arise.

By understanding kennel cough—its symptoms, causes, treatment, and prevention—you can take proactive steps to keep your dog safe, healthy, and happy in every social setting.
