Your dog has been coughing more than usual, and it sounds dry, almost like a honking noise. You’re worried it might be something serious, but before you panic, let’s talk about one of the most common causes: kennel cough. This highly contagious respiratory condition can seem alarming, but with the right knowledge and care, your pup will likely recover quickly. Here’s what you need to know.

⚠️ What to Watch For

Kennel cough, also known as canine infectious respiratory disease complex (CIRDC), is a condition that affects the respiratory system of dogs. The symptoms can vary from mild to severe, and knowing what to look out for is key to ensuring your dog gets the care they need.

Common symptoms of kennel cough include:

  • A persistent, dry, hacking cough (often described as a “honking” sound)
  • Retching or gagging, especially after coughing
  • Runny nose or nasal discharge
  • Watery eyes
  • Decreased energy or mild lethargy
  • Loss of appetite
  • Sneezing

In more severe cases, kennel cough can lead to secondary infections like pneumonia. Symptoms of a more serious infection might include fever, difficulty breathing, or a wet, productive cough. If you notice any of these, it’s time to seek veterinary care immediately.

🔍 Possible Causes

Kennel cough is not caused by a single pathogen. Instead, it’s usually the result of multiple infectious agents working together, including bacteria and viruses. The most common culprits include:

  • Bordetella bronchiseptica (a type of bacteria often linked to kennel cough)
  • Canine parainfluenza virus
  • Canine adenovirus type 2
  • Mycoplasma species

These pathogens spread easily in environments where dogs are in close contact, such as kennels, dog parks, grooming salons, or shelters. That’s why it’s called “kennel cough.” It’s transmitted through respiratory droplets when an infected dog coughs, sneezes, or shares toys, bowls, or bedding with other dogs.

✅ What You Can Do at Home

If your dog shows mild symptoms of kennel cough and is otherwise healthy, there are several ways you can help them recover at home:

  • Provide plenty of rest: Limit physical activity to allow their body to heal.
  • Use a humidifier: Moist air can help soothe their irritated airways.
  • Hydration is key: Ensure your dog has access to fresh water at all times to stay hydrated.
  • Minimize exposure to irritants: Avoid cigarette smoke, strong cleaning products, or anything that might worsen their coughing.
  • Consider supportive care: Some dogs may benefit from honey (in small amounts) to soothe their throat. Always consult your vet before trying home remedies.

Most cases of kennel cough resolve on their own within 1–3 weeks. However, some dogs, especially puppies, seniors, or those with weakened immune systems, may require additional care.

💡 When to Call a Vet

While mild cases of kennel cough often don’t require veterinary intervention, there are times when reaching out to a vet is essential. Contact a vet if:

  • Your dog is coughing non-stop or seems to be in distress.
  • They develop a fever, lethargy, or loss of appetite.
  • The cough persists for more than three weeks.
  • They have difficulty breathing or show signs of pneumonia (e.g., wet cough, rapid breathing).

In these situations, your vet might recommend diagnostic tests such as chest X-rays or bloodwork to rule out other conditions like heart disease, collapsed trachea, or bronchitis. Treatment may include antibiotics (if a bacterial infection is suspected), cough suppressants, or even nebulization therapy.

According to VCA Animal Hospitals, vaccination can help prevent kennel cough caused by Bordetella bronchiseptica and other pathogens (source). If your dog frequently interacts with other dogs, talk to your vet about vaccination options.

FAQs

Q: Can humans catch kennel cough from dogs?
A: It’s rare, but in some cases, people with weakened immune systems may be at risk of catching Bordetella bronchiseptica. If you’re concerned, consult your doctor.

Q: Is kennel cough dangerous for puppies?
A: Puppies are more vulnerable to complications like pneumonia, so it’s important to monitor their symptoms closely and seek veterinary care if they worsen.
