Kennel Cough Symptoms in Dogs: What to Watch For

Key takeaways:

• Kennel cough is a common respiratory issue in dogs that can spread rapidly in places where dogs interact, like parks or grooming facilities.
• Early recognition of symptoms, such as a distinctive honking cough and changes in energy or appetite, is crucial for adequate care and prevention.
• Preventive measures, including regular vaccinations and wellness checks, protect dogs, especially puppies and those with compromised immune systems, from kennel cough.

That strange, honking cough in the middle of the night? It’s enough to send any dog parent sitting up in bed. If your pup sounds like they’ve swallowed a squeaky toy or started mimicking a goose, you might be dealing with kennel cough — one of dogs’ most common respiratory issues. Despite its name, kennel cough isn’t limited to boarding facilities. It can show up anywhere dogs mix and mingle, from your local park to daycare or the groomer.

Knowing kennel cough symptoms in dogs can help you take early, informed action. Most otherwise healthy pups recover within a few weeks with rest and support. But spotting the signs early and talking with your vet can help avoid complications for puppies, seniors, or dogs with underlying conditions. PetHealthMD offers clear guidance to help you understand what to look for and how to support your dog’s recovery every step of the way.

Recognizing kennel cough symptoms

Symptoms of kennel cough usually develop three to four days after exposure to the virus or bacteria that cause it. This incubation period makes it tricky, since a dog may seem completely fine at the dog park but start coughing days later.

Spotting kennel cough symptoms in dogs early helps you respond quickly, protect other pets, and ease your dog’s recovery. Though the illness is often mild, it’s highly contagious, so catching the first signs makes a real difference for your pup and the community of dogs they interact with.

Here are the most common kennel cough symptoms to watch for:

1. Persistent, honking cough

The most common sign of kennel cough is a dry, forceful cough that sounds a lot like a goose honk. It might come in short bursts or long fits, especially after activity, excitement, or pressure on the throat (like from a collar or leash tug). Some dogs may gag or retch at the end of coughing fits, or show signs of throat discomfort — frequent swallowing, grunting, or neck-stretching. If your dog is otherwise active but can’t seem to shake this cough, it’s time to take notice.

2. Nasal discharge and sneezing

Kennel cough often causes dogs to show mild upper respiratory symptoms, including a runny nose. The discharge is usually clear or white, and repeated sneezing may accompany it. While these signs can resemble a cold, it’s important not to dismiss them, especially when paired with coughing.

3. Reduced energy or playfulness

Even if your dog still wants to play, you might notice a dip in their usual enthusiasm. Dogs fighting kennel cough may seem more tired than usual, nap more frequently, or hesitate to join in on their favorite games. These changes are often subtle, but they’re worth noting — especially if they appear alongside other symptoms.

4. Loss of appetite or interest in water

Some dogs with kennel cough experience reduced appetite or reluctance to drink water, particularly if their throat feels irritated. Skipping a meal here and there might not be unusual, but if your dog consistently turns away from food or starts drinking less, it’s time to consult your vet.

What to do if you notice kennel cough symptoms in your dog

If your dog starts showing signs of kennel cough:

• Limit their exposure to other dogs right away. Most vets recommend keeping your dog away from other dogs for at least 14 days after symptoms begin, though some may still spread germs for a few weeks after that.
  
• Keep them calm and comfortable, since excitement can trigger more coughing.
  
• Avoid collar pressure by using a harness instead.
  
• Contact your veterinarian to confirm the diagnosis and get treatment guidance tailored to your dog.

Most importantly, stay positive — many dogs bounce back quickly with proper care. 

When to call the vet about kennel cough

Most healthy dogs recover from kennel cough within 10 to 14 days with rest, hydration, and extra care at home. But some symptoms may signal that your dog needs additional support, especially if they’re young, older, or have an underlying health condition.

Here are signs that it’s time to check in with your veterinarian:

• Coughing that gets worse or doesn’t improve after several days
  
• Lack of interest in food or water
  
• Lethargy, listlessness, or signs of fever
  
• Labored breathing, wheezing, or unusual chest sounds

Even if you’re unsure whether it’s serious, your vet can help you decide on the next steps.

Effective prevention strategies for kennel cough

Keeping your dog healthy and social doesn’t have to be complicated — a few consistent habits can go a long way in reducing the risk of kennel cough. Like us, dogs benefit from routine care, a clean environment, and mindful interactions with others. Here’s how to help your pup stay protected.

Work with your vet to stay ahead

Veterinarians are your best partners when it comes to preventing kennel cough:

• Vaccinate against Bordetella, one of the most common causes of kennel cough. The vaccine is quick — usually under 15 minutes — and costs around $25 to $45. It’s often recommended once a year, especially for dogs that visit dog parks, boarding kennels, or groomers regularly.
  
• Book regular checkups every 6 to 12 months. These wellness visits help strengthen your dog’s immune system and ensure vaccinations stay current.

Build a healthy home environment

Your everyday habits at home play a significant role in prevention:

• Keep your dog’s space clean. Spend a few minutes each day rinsing food and water bowls, and refresh their bedding and toys weekly to help reduce germs.
  
• Support their immune system with good nutrition. A balanced diet, clean water, and plenty of rest help your dog naturally fight off infections, including respiratory ones like kennel cough.

Practice safe socializing

You don’t have to keep your dog away from their favorite play spots — just take a few thoughtful precautions:

• Visit dog parks during quieter hours. Early mornings or weekday evenings typically mean fewer dogs and better air circulation, which can help reduce exposure to airborne viruses.
  
• Choose well-ventilated facilities. Ask about cleaning routines and vaccination policies before booking, whether for grooming or daycare. Clean, open spaces with solid health protocols can help lower your dog’s risk.
  
• Be extra cautious in winter. Kennel cough cases tend to spike in colder months, so a little added care—like avoiding crowded indoor spaces—goes a long way during this chillier season.

Frequently asked questions about kennel cough

Can people catch this cough from their dogs?

Healthy people rarely catch kennel cough. If you or someone in your household has a weakened immune system, take extra precautions, such as wearing a mask when caring for your dog, washing hands frequently, and consulting your doctor for specific guidance.

Will this affect my dog’s health in the future?

Most dogs bounce back completely within 1-2 weeks without lasting effects. Talk to your vet about vaccination options and ways to boost your dog’s immune system to prevent future episodes. Senior dogs, puppies, or dogs with other health conditions might need extra care and monitoring during recovery.

Is kennel cough more serious for certain dogs?

Yes. While most healthy adult dogs recover easily, puppies, seniors, and those with chronic illnesses or weakened immune systems may be at higher risk for complications like pneumonia. If your dog falls into one of these groups, talk to your vet at the first sign of coughing or fatigue. Early care can make a big difference in recovery.

Can my dog get kennel cough even if they’ve been vaccinated?

It’s possible. The Bordetella vaccine doesn’t protect against every cause of kennel cough — just the most common one. Like the flu shot for humans, it can reduce the severity of symptoms or help prevent infection, but it’s not 100% effective. That’s why good hygiene and thoughtful socializing are still important.

Protecting your dog from kennel cough

Kennel cough is a common concern, but with the proper habits, it’s one you can manage confidently. Staying up to date on vaccines, keeping your dog’s environment clean, and checking in regularly with your vet all play a part in prevention. A little extra care goes a long way for puppies, senior dogs, or those with other health issues.

Your vet is your best partner when it comes to building a plan that fits your dog’s lifestyle, especially if they’re often around other dogs. And if symptoms do show up, early action makes all the difference. PetMeds makes it easier to stay prepared with vet-approved medications, vaccines, and wellness essentials delivered right to your door.
