Kennel cough, medically known as canine infectious tracheobronchitis, is a highly contagious respiratory infection in dogs. Often characterized by a persistent, dry cough, this condition can affect dogs of all breeds, ages, and sizes. Although generally not life-threatening, kennel cough can lead to severe complications if left untreated, particularly in young puppies, elderly dogs, and those with weakened immune systems.
How Kennel Cough is Spread
Transmission
Kennel cough is primarily spread through airborne droplets, making it highly transmissible in places where dogs are in close contact, such as kennels, dog parks, grooming facilities, and shelters. Several pathogens, including the Bordetella bronchiseptica bacterium, canine parainfluenza virus, and canine adenovirus type 2 can cause the infection. Dogs can contract kennel cough through:
- Direct contact with infected dogs (sniffing, licking, or sharing food/water bowls).
- Inhalation of airborne droplets released when an infected dog coughs or sneezes.
- Contact with contaminated surfaces (kennels, leashes, toys). (Source)
Symptoms of Kennel Cough
The most common symptom of kennel cough is a dry, hacking cough that may sound like a goose honk. Other symptoms include:
- Retching or gagging, especially after exercise.
- Sneezing or nasal discharge.
- Lethargy or reduced energy levels.
- Loss of appetite.
- Mild fever.
These symptoms can appear 2 to 10 days after exposure to the infection and can last up to three weeks. (Source)
Causes of Kennel Cough in Dogs
Kennel cough is usually caused by a combination of bacterial and viral infections. The most common culprits include:
- Bordetella bronchiseptica: A bacterium that is the primary cause of kennel cough.
- Canine parainfluenza virus: A virus that affects the respiratory system.
- Canine adenovirus type 2: A virus that can cause respiratory and liver infections. (Source)
Who is Vulnerable?
All dogs are susceptible to kennel cough, but certain groups are more vulnerable:
- Puppies: Their immature immune systems make them more prone to infections.
- Senior dogs: Aging immune systems can be less effective at fighting off infections.
- Dogs with pre-existing conditions: Conditions like heart disease or respiratory issues can make it harder to recover from kennel cough.
- Dogs in high-density environments: Dogs in shelters, kennels, or boarding facilities are at a higher risk due to close proximity to other dogs. (Source)

Potential Problems and Complications
While kennel cough is usually mild, it can lead to serious complications in certain cases:
- Pneumonia: If the infection spreads to the lungs, it can cause pneumonia, a potentially life-threatening condition.
- Chronic bronchitis: Repeated infections or prolonged symptoms can lead to chronic bronchitis.
- Worsening of pre-existing conditions: Dogs with respiratory issues or weakened immune systems may experience more severe symptoms. (Source)
Treatment for Kennel Cough
Veterinary Care for kennel cough in dogs
Most cases of kennel cough resolve on their own within a few weeks. However, veterinary care is essential if your dog is showing severe symptoms or is at risk of complications. Treatment options include:
- Antibiotics: Prescribed if a bacterial infection is confirmed or suspected.
- Cough suppressants: To reduce the severity of the cough and help the dog rest.
- Anti-inflammatory medications: To reduce inflammation in the airways
Vaccination and Prevention
Vaccination
Vaccination is the most effective way to prevent kennel cough. Vaccines are available for:
- Bordetella bronchiseptica: Often administered as an intranasal or injectable vaccine.
- Canine parainfluenza virus and adenovirus: Usually included in combination vaccines.
Prevention Tips
- Avoid crowded dog areas: Limit your dog’s exposure to high-risk environments, especially during outbreaks.
- Ensure good ventilation: Proper airflow in kennels and indoor areas can reduce the spread of airborne pathogens.
- Regular cleaning: Disinfect toys, bowls, and surfaces regularly to prevent contamination.

Protecting Humans and Dogs
Human Safety
While kennel cough is primarily a canine disease, Bordetella bronchiseptica can occasionally infect humans, particularly those with compromised immune systems. To protect yourself and others:
- Practice good hygiene: Wash your hands after handling your dog or cleaning their belongings.
- Seek veterinary advice: If your dog shows symptoms, consult a veterinarian promptly to reduce the risk of transmission. (Source)
Global Perspective: What Experts Say
Global organizations such as the American Veterinary Medical Association (AVMA) and the World Small Animal Veterinary Association (WSAVA) recommend regular vaccination and prompt treatment to manage kennel cough. They emphasize the importance of public awareness, especially in communal settings like shelters and kennels, where the risk of outbreak is higher.
Dr. John Ellis, a prominent veterinarian and researcher, highlights the importance of vaccination, stating, “Vaccination against Bordetella and parainfluenza is crucial in preventing the spread of kennel cough, especially in environments where dogs are in close contact.” (Source)
Conclusion
Kennel cough is a common but manageable respiratory infection in dogs. Dog owners can protect their pets from this condition by understanding its causes, symptoms, and preventive measures. Regular vaccination, good hygiene, and prompt veterinary care are key to keeping your dog healthy and preventing the spread of kennel cough in the community.
