Kennel Cough in Dogs: Causes, Symptoms, and Treatment

3 min read

As pet owners, we all want our dogs to be healthy, happy, and full of energy. But sometimes, they can pick up illnesses—especially if they’ve recently been around other dogs. One of the most common contagious illnesses in dogs is kennel cough, a respiratory condition that can sound alarming but is often manageable with the right care.

In this post, we’ll cover what kennel cough is, how dogs catch it, symptoms to watch for, treatment options, and steps you can take to prevent it.

Why Kennel Cough Happens

Kennel cough—medically known as canine infectious tracheobronchitis—is a highly contagious respiratory infection. It’s caused by a combination of viruses and bacteria, most notably Bordetella bronchiseptica. These germs inflame your dog’s windpipe and voice box, leading to that signature hacking cough.

Dogs usually catch kennel cough in environments where lots of dogs are together, such as:

• Boarding kennels

• Dog daycare facilities

• Grooming salons

• Dog parks

• Veterinary waiting rooms

  
  

It spreads through airborne droplets, direct contact, or contaminated surfaces—similar to how a cold spreads among humans.

Common Signs of Kennel Cough

Kennel cough symptoms can range from mild to severe, so it’s important to monitor your dog closely. The most common signs include:

• A persistent, honking cough (often worse at night)

• Gagging or retching after coughing

• Mild fever

• Nasal discharge

• Lethargy

• Loss of appetite in more severe cases

💡 Tip: Kennel cough often sounds worse than it is, but if your dog is lethargic, refuses food, or has trouble breathing, seek veterinary care immediately.

How Kennel Cough Is Treated

The good news? Most healthy dogs recover from kennel cough within 1–3 weeks with supportive care. Your vet may recommend:

1. Rest and Hydration - Keep your dog calm and stress-free to help recovery.

2. Cough Suppressants or Anti-Inflammatories - Prescribed to ease discomfort and reduce irritation.

3. Antibiotics - Used if a bacterial infection (like Bordetella) is suspected or confirmed.

4. Nebulization or Humidification - Adding moisture to the air can soothe your dog’s airways.

📣 Important: Always follow your vet’s dosing instructions. Human cough medicines are not safe for dogs unless prescribed.

Preventing Kennel Cough

Prevention is key—especially if your dog regularly interacts with other dogs. Steps to reduce risk include:

• Vaccination – Bordetella and canine parainfluenza vaccines can significantly reduce risk.

• Avoid Crowded Dog Areas During Outbreaks – If there’s a known outbreak, skip the dog park for a few weeks.

• Good Hygiene – Wash your hands and sanitize leashes, bowls, and toys after contact with other dogs.

  
  

Why Early Detection Matters

Catching kennel cough early means faster treatment, less discomfort, and a reduced chance of spreading it to other dogs. If you notice a persistent cough—especially after boarding or social events—contact your vet for guidance.
