Kennel Cough in Dogs: Causes, Symptoms, and Recovery
If you’ve ever heard your dog make a loud, harsh, goose-like honk that leaves them gagging afterward, you’ve likely encountered kennel cough. Formally called canine infectious tracheobronchitis, it’s one of the most common respiratory infections in dogs — and one of the most contagious. Most healthy adult dogs recover without complications, but knowing the signs and when to call your vet is important.
| Factor | Details |
|---|---|
| Primary Cause | Bordetella bronchiseptica + viral co-infections |
| Spread | Airborne, direct contact, shared water bowls |
| Incubation Period | 2–14 days after exposure |
| Duration | 1–3 weeks in healthy adults |
| Vaccine Available | Yes (Bordetella; injectable, intranasal, oral) |
| High-Risk Groups | Puppies, senior dogs, immunocompromised dogs |
How Kennel Cough Spreads
Despite the name, a dog doesn’t need to visit a kennel to get it. Kennel cough spreads rapidly anywhere dogs congregate — dog parks, grooming salons, vet waiting rooms, training classes, and yes, boarding kennels. The bacteria and viruses that cause it travel through the air and on shared surfaces.
Symptoms Beyond the Cough
The distinctive honking cough is the hallmark sign, but dogs may also show: runny nose, sneezing, watery eyes, and mild lethargy. Appetite usually remains normal in mild cases. Fever, significant lethargy, loss of appetite, or labored breathing suggest a more serious infection — call your vet promptly in these cases.
Treatment and Recovery
Mild kennel cough in a healthy adult dog often resolves with rest, hydration, and avoiding further irritants like smoke or dusty environments. Your vet may prescribe a cough suppressant, antibiotics (to treat Bordetella or prevent secondary infections), or anti-inflammatories depending on severity. Keep infected dogs away from other dogs until symptoms resolve.
Frequently Asked Questions
What does kennel cough sound like?
Kennel cough produces a loud, harsh, honking cough that sounds like a goose honking. It may be followed by gagging or bringing up white foamy mucus. Owners often describe it as sounding like something is stuck in the dog’s throat.
Is kennel cough serious?
For healthy adult dogs, kennel cough is usually mild and resolves on its own within 1–3 weeks. However, it can progress to pneumonia in puppies, elderly dogs, or immunocompromised dogs. Call your vet if symptoms are severe, if your dog stops eating, or if they seem lethargic.
Can my dog get kennel cough if they’ve been vaccinated?
The Bordetella vaccine reduces the severity and likelihood of infection but does not prevent all cases, since kennel cough can be caused by multiple pathogens. Vaccinated dogs who contract it typically have milder symptoms.
