What is kennel cough and how does it affect dogs?
Kennel cough, clinically known as infectious tracheobronchitis, is a highly contagious respiratory infection in dogs caused by a combination of bacteria and viruses — most commonly Bordetella bronchiseptica. It produces a harsh, honking cough and spreads rapidly in places where dogs gather. Most healthy adult dogs recover within 1–3 weeks with appropriate care.
MaxPetz in Delhi provides veterinary care for kennel cough, including diagnosis, treatment, and preventive vaccination, with a focus on cutting-edge technology and compassionate service for your pet.
Key fact: Kennel cough is not a single pathogen — it is a complex of infections. Vaccination targets the most common causative agents, significantly reducing severity and spread.
What causes kennel cough in dogs?
Kennel cough results from one or more infectious agents that inflame the trachea and bronchi. Transmission occurs through airborne droplets, direct contact with infected dogs, or contaminated surfaces — making shared spaces such as boarding kennels, dog parks, and grooming salons common sites of exposure.
- Bordetella bronchiseptica — the primary bacterial cause; often called simply "Bordetella in dogs"
- Canine parainfluenza virus — a frequent viral co-infector
- Canine adenovirus type 2 — contributes to respiratory inflammation
- Canine distemper virus — less common but can complicate the disease
- Mycoplasma spp. — bacterial co-infection that can worsen symptoms
Risk is highest in dogs that have recently been in boarding facilities, dog shows, shelters, or training classes — hence the common name "kennel cough."
What are the first signs of kennel cough in a dog?
Symptoms typically appear 3–10 days after exposure. The hallmark sign is a forceful, persistent cough that owners often describe as a honking or goose-like sound — this is the characteristic kennel cough sound. In mild cases, dogs remain alert and continue eating normally.
| Symptom | Description |
|---|---|
| Honking cough | Harsh, dry, repetitive cough; often triggered by excitement or pulling on the lead |
| Retching or gagging | May follow coughing episodes; sometimes produces white foam |
| Nasal discharge | Clear to slightly cloudy runny nose |
| Sneezing | Intermittent; more common in early stages |
| Mild lethargy | Slightly reduced energy; appetite usually maintained in uncomplicated cases |
| Fever (severe cases) | Indicates possible secondary infection or pneumonia — requires prompt veterinary attention |
Warning: Puppies, senior dogs, and immunocompromised dogs can develop severe pneumonia from kennel cough. If your dog is breathing rapidly, refusing food, or appears very weak, seek veterinary care immediately.
How is kennel cough treated in dogs?
Treatment depends on the severity of the infection. Mild, uncomplicated kennel cough in otherwise healthy adult dogs often resolves with supportive care. More severe cases — or those involving puppies, elderly dogs, or dogs with underlying conditions — require veterinary-prescribed medication.
Veterinary treatment options include:
- Antibiotics — prescribed when Bordetella bronchiseptica or secondary bacterial infection is confirmed or strongly suspected; doxycycline and amoxicillin-clavulanate are among the antibiotics commonly used by veterinarians for this condition
- Cough suppressants — to reduce the frequency and discomfort of coughing, prescribed at veterinary discretion
- Anti-inflammatory medication — to reduce airway inflammation in moderate cases
- Nebulisation or steam therapy — may be recommended to soothe irritated airways
- Hospitalisation — required in severe cases with pneumonia or respiratory distress
Supportive home care (always alongside veterinary guidance, not as a replacement):
- Keep your dog rested and away from other dogs to prevent spread
- Use a harness instead of a collar to avoid pressure on the trachea
- Ensure access to fresh water at all times
- Run a humidifier in the room to ease airway irritation
- Avoid smoke, dust, and strong chemical odours
Note: Never administer human cough medicines or antibiotics to your dog without a veterinary prescription. Many human medications are toxic to dogs.
When should you take your dog to the vet for kennel cough?
Not every cough requires an emergency visit, but certain signs indicate that professional veterinary assessment is necessary without delay. Use the guide below to decide when to act.
- Coughing persists for more than 7–10 days without improvement
- Your dog develops a fever (rectal temperature above 39.5°C)
- Breathing becomes rapid, laboured, or noisy at rest
- Your dog stops eating or drinking for more than 24 hours
- Nasal or eye discharge turns yellow or green (indicates bacterial secondary infection)
- Your dog is a puppy under 6 months, a senior dog, or has a known health condition
- Symptoms worsen rather than plateau or improve after 3–4 days
Puppies are at particular risk of rapid deterioration — if a puppy under 6 months is coughing, a same-day veterinary consultation is advisable.
Can kennel cough be prevented with a vaccine?
Yes. The kennel cough vaccine — commonly called the Bordetella vaccine or dog cough vaccine — is the most effective preventive measure available. It does not guarantee complete immunity (because multiple pathogens cause the syndrome), but it significantly reduces the severity and duration of illness.
Vaccine formats available:
- Injectable Bordetella vaccine — administered subcutaneously; requires 2–4 weeks to reach full effect
- Intranasal vaccine — delivered directly into the nostril; provides faster local immunity
- Oral vaccine — available in some markets; easy to administer
Who should be vaccinated?
- Dogs that visit boarding kennels, dog parks, or grooming salons
- Dogs attending training classes or dog shows
- Dogs in multi-dog households
- Puppies as part of their core vaccination schedule
Booster frequency varies by product and individual risk — your veterinarian will advise the appropriate schedule. Learn more about pet vaccination services at MaxPetz Delhi, where the team can assess your dog's vaccination history and recommend the right protocol.
Tip: Many boarding facilities in Delhi require proof of a current Bordetella vaccination before admission. Book a vaccination appointment in advance of any planned boarding.
