Prevent Kennel Cough in Dogs: Easy & Effective Tips to Keep Pups Safe

If you’ve ever walked into a dog park or a boarding facility and heard a chorus of raspy, honking coughs, you might have just encountered kennel cough in action. It’s one of the most common respiratory infections in dogs, and trust me—I’ve seen my fair share of cases in my years working in veterinary clinics. The good news? You can absolutely take steps to prevent kennel cough in dogs and keep your pup safe from this nasty, hacking illness. Whether you’re a first-time dog parent or a seasoned pet owner, let’s break it all down in a way that’s easy to understand.

What Exactly Is Kennel Cough?

Kennel cough, officially known as canine infectious tracheobronchitis, is like the dog version of a cold—or more accurately, bronchitis. It’s highly contagious and spreads like wildfire in places where dogs gather, like boarding kennels, doggy daycare, and even at the groomer’s.

In my time working in vet clinics, I can’t count how many worried pet parents have come in saying, “My dog has this weird cough that sounds like he’s choking.” If you’ve ever heard that harsh, honking cough, you know exactly what they mean. The infection can be caused by several different viruses and bacteria, but the most notorious culprit is Bordetella bronchiseptica. It weakens the respiratory system, making dogs more susceptible to other infections.

How Do Dogs Catch Kennel Cough?

Kennel cough spreads through the air, contaminated surfaces, and even direct contact between dogs. If an infected dog sneezes or coughs, tiny droplets carrying the bacteria or viruses become airborne. Another dog simply breathing in those particles can get infected. And don’t even get me started on shared water bowls and toys—those are breeding grounds for germs!

Common Places Where Dogs Get Exposed

• Boarding kennels & doggy daycare – Close quarters mean easy transmission.
• Dog parks – Lots of sniffing, playing, and accidental droplet sharing.
• Training classes – Group settings can expose pups to infected dogs.
• Grooming salons – Shared air and surfaces increase risk.
• Vet clinics – Some dogs may be contagious before showing symptoms.

How Long Is It Contagious?

Once infected, a dog can spread kennel cough for up to three weeks—sometimes longer, depending on their immune system. This means even after they stop coughing, they might still be spreading germs to other dogs.

Recognizing the Symptoms Early

Early detection is key! The most telltale sign is the infamous honking cough, but kennel cough can also come with other symptoms, including:

• A dry, hacking cough that sounds like a goose honk
• Gagging or retching (sometimes bringing up foam)
• Runny nose or sneezing
• Mild fever
• Loss of appetite (in more severe cases)
• Lethargy (but usually not extreme)

Most mild cases clear up on their own, but I always tell pet parents—if your dog is struggling to breathe, acting lethargic, or not eating, get to a vet ASAP.

How to Prevent Kennel Cough in Dogs

Alright, now that we know what kennel cough is and how it spreads, let’s talk about what really matters—how to prevent kennel cough in dogs. Trust me, prevention is a whole lot easier (and cheaper) than dealing with a sick, miserable pup who sounds like they swallowed a squeaky toy.

1. Get Your Dog Vaccinated

Hands down, the best way to reduce the risk of kennel cough is vaccination. There are three different types of Bordetella vaccines: injectable, intranasal (nose drops), and oral (a liquid squirted into the mouth). Vets usually recommend it for dogs who regularly socialize with other pups.

From my experience working in vet clinics, the intranasal vaccine tends to kick in faster, but some dogs absolutely hate having drops up their nose. If your dog is one of those drama queens (no judgment!), the oral or injectable versions might be a better choice.

How often should your dog get vaccinated? It depends. Some vaccines last a year, while others need a booster every six months. Your vet will help decide what’s best based on your dog’s lifestyle.

2. Avoid High-Risk Environments (When Possible)

Let’s be real—avoiding dog parks, daycare, and boarding facilities isn’t always an option. But if there’s an outbreak going around, you might want to skip these places until things settle down.

If you must board your dog, look for a facility that requires proof of vaccination. The best ones have good ventilation, strict cleaning protocols, and enough space to prevent overcrowding.

3. Keep Your Dog’s Immune System Strong

A strong immune system can make all the difference when it comes to fighting off infections. Here are some ways to keep your pup in tip-top shape:

• Feed a high-quality diet – Good nutrition supports a healthy immune system. Look for dog food rich in protein, antioxidants, and omega fatty acids.
• Provide fresh water – Hydration is key to keeping the respiratory tract moist and healthy.
• Regular exercise – A fit dog is a healthy dog! Just don’t overdo it if your pup is recovering from an illness.
• Reduce stress – Stress weakens the immune system. Try to keep a calm and stable environment, especially if your dog gets anxious in new situations.

4. Practice Good Hygiene & Cleaning Habits

If you have multiple dogs or bring your pup to social settings, basic hygiene can go a long way in preventing kennel cough.

• Wash food and water bowls regularly.
• Disinfect shared toys and bedding.
• Wipe down leashes, collars, and harnesses.
• Use pet-safe disinfectants in your home.

Oh, and if you have a dog recovering from kennel cough, keep them separated from healthy dogs until they’re no longer contagious!

5. Improve Air Quality & Ventilation

Did you know that poor air circulation can make it easier for airborne bacteria and viruses to spread? In vet clinics and boarding facilities, we always emphasized proper airflow to reduce infection risks.

At home, consider using an air purifier to filter out germs and allergens. If your dog spends time indoors with other pups (like at a daycare), ask if they have a good ventilation system in place.

What to Do If Your Dog Is Exposed to Kennel Cough

Let’s say your dog was around a coughing pup at daycare—what now? First, don’t panic. Not every exposure leads to infection, but it’s smart to be proactive.

• Monitor for symptoms – Watch for that telltale cough over the next 3-10 days.
• Support their immune system – Extra hydration, rest, and proper nutrition can help.
• Keep them away from other dogs – Just in case they start showing symptoms.

And if you do notice a cough developing, call your vet. Most cases are mild, but it’s always good to get professional advice.

Case Studies & Real-Life Examples

Let’s take a look at some real-life cases I’ve encountered during my years in veterinary clinics. Every dog reacts differently to kennel cough, and these stories will give you an idea of how it plays out in different situations.

Case #1: The Doggy Daycare Outbreak

We once had a client, Sarah, who brought in her golden retriever, Max, after he started hacking uncontrollably. She had just picked him up from a local daycare, where multiple dogs had started coughing. Max was still eating and playing, but the cough was persistent.

What we did: Since Max was otherwise healthy, we recommended rest, hydration, and a humidifier at home. Within 10 days, he was back to his normal, tail-wagging self.

Case #2: The Senior Dog Scare

Then there was Bella, a 12-year-old dachshund with a heart condition. When she caught kennel cough, it hit her harder than most dogs. She struggled with breathing and had a mild fever.

What we did: Because of her age and health risks, we put her on a vet-prescribed cough suppressant and antibiotics to prevent secondary infections. She recovered, but it took longer—about three weeks.

The takeaway? Healthy, young dogs usually recover quickly, but for puppies, seniors, or dogs with existing conditions, kennel cough can be more serious.

Key Takeaways: What You Need to Remember

• Kennel cough is highly contagious, spreading through air, direct contact, and contaminated surfaces.
• Vaccination is the best prevention, but it doesn’t guarantee 100% immunity.
• Most cases are mild and resolve within 1-3 weeks without medical intervention.
• Some dogs need extra care—puppies, seniors, and dogs with weakened immune systems should see a vet if symptoms persist.
• Good hygiene, ventilation, and a strong immune system help reduce the risk of infection.

FAQs

Can humans catch kennel cough from dogs?

It’s extremely rare, but possible—especially for people with weakened immune systems. The main culprit, Bordetella bronchiseptica, is in the same family as whooping cough in humans. However, it’s not a common zoonotic disease.

How long does kennel cough last?

Most mild cases clear up within 10 to 14 days, but some dogs can have a lingering cough for up to three weeks. If symptoms persist beyond that, check with your vet.

Can a vaccinated dog still get kennel cough?

Yes, but symptoms will likely be milder. The vaccine protects against the most common strain of Bordetella but doesn’t cover every possible respiratory pathogen.

Is there a home remedy for kennel cough?

While vet care is always the safest route, some home remedies can help ease symptoms:

• Use a humidifier to soothe the throat.
• Offer honey (in small amounts) for its natural antibacterial properties.
• Encourage hydration with fresh water and bone broth.
• Keep your pup calm—excessive barking can make the cough worse.
