Kennel Cough in Dogs — symptoms, vet costs & insurance

Kennel cough is highly contagious but usually mild — most cases self-resolve, while severe cases cost $200-$500 to treat. Also called infectious tracheobronchitis, it causes a distinctive honking cough that sounds worse than it usually is. The Bordetella vaccine costs $20-$40 and is required by most boarding facilities. Puppies, senior dogs, and immunocompromised dogs are at risk for complications.

Key Facts & Real Vet Costs

What Causes Kennel Cough

Kennel cough is caused by a combination of bacteria (most commonly Bordetella bronchiseptica) and viruses (parainfluenza, adenovirus, and others). It spreads through airborne droplets, direct contact, and contaminated surfaces. Dogs in close quarters — boarding kennels, dog parks, shelters, grooming salons — are at highest risk. The infection inflames the trachea and bronchi, causing a persistent cough. Highly contagious in crowded environments

Symptoms — What to Watch For

A persistent, forceful cough — often described as a honking or hacking sound. Retching or gagging after coughing fits. Runny nose and sneezing. Mild lethargy. Most dogs remain active and have normal appetite despite the cough. Watch for warning signs of complications: fever, thick nasal discharge, loss of appetite, and difficulty breathing. The distinctive honking cough is the hallmark symptom

Diagnosis — $50-$100

A physical exam ($50-$100) with the characteristic cough and recent exposure history is usually enough for diagnosis. Your vet may induce coughing by gently pressing the trachea. Chest X-rays ($150-$300) are only needed if pneumonia is suspected. PCR testing ($100-$200) can identify the specific pathogen but is rarely necessary for routine cases. Average $50-$100

Treatment — $0-$500

Mild cases often self-resolve within 1-3 weeks with rest and isolation. Cough suppressants ($20-$50) ease discomfort. Antibiotics ($30-$80) are prescribed for secondary bacterial infection or at-risk dogs. Severe cases with pneumonia require hospitalization ($500-$2,000+). Humidifier and honey can help soothe the cough. Bordetella vaccine costs $20-$40. Average $200-$500 for treated cases

Total Cost — $50-$600

Mild cases: just an exam. Severe cases with antibiotics: $200-$500. Pneumonia complications can reach $2,000+.

Risk — All Breeds, All Ages

Any dog exposed to other dogs is at risk. Puppies, seniors, and immunocompromised dogs face higher complication risk.

Recovery — 1-3 Weeks

Most dogs recover within 1-3 weeks. The cough can linger for several weeks after the infection clears. Isolate for 2 weeks.

Prevention

Bordetella vaccine ($20-$40) reduces severity. Annual boosters for dogs in social settings. Vaccine doesn't prevent all strains.

Insurance Traps Kennel cough is usually inexpensive — but complications can add up.
Red flag · Waiting period

Kennel Cough Coverage Basics

Most pet insurance policies cover kennel cough treatment as a standard illness. Standard 14-day illness waiting period applies. The vet exam, antibiotics, and cough medication are typically covered. Hospitalization for pneumonia complications is also covered.

Red flag · Waiting period

The Waiting Period Trap

Kennel cough has a short incubation period (2-14 days). If your dog contracts it shortly after enrolling, the claim may fall within the 14-day waiting period and be denied. This is a common scenario — people buy insurance before boarding, then the dog gets kennel cough during the waiting period.

Red flag · Deductible

Cost vs Deductible

Most kennel cough cases cost $50-$300 — often at or below your annual deductible. Filing a claim may not save you money on a mild case. Insurance value kicks in if kennel cough develops into pneumonia requiring hospitalization ($500-$2,000+).

Red flag · Routine exclusion

Vaccination Coverage

The Bordetella vaccine is considered preventive care — not covered by standard illness/accident plans. Only wellness add-on plans cover vaccinations. The vaccine costs $20-$40 and is one of the cheapest preventive measures available.

Common Questions Real answers about costs, treatment, and insurance coverage.
0What does kennel cough sound like?
Kennel cough produces a distinctive, forceful, dry cough often described as a honking or hacking sound — some owners say it sounds like their dog has something stuck in their throat. The cough may be followed by retching or gagging. It's often triggered by excitement, exercise, or gentle pressure on the trachea (like pulling on a leash). Despite the alarming sound, most dogs with kennel cough remain alert and active between coughing fits.
1How much does kennel cough treatment cost?
Mild cases may only require a vet exam ($50-$100) and resolve on their own. When treatment is needed, antibiotics cost $30-$80, cough suppressants $20-$50, and anti-inflammatories $20-$40. Total for a typical treated case runs $200-$500. If kennel cough progresses to pneumonia requiring hospitalization, costs can reach $500-$2,000+. The Bordetella vaccine costs $20-$40 for prevention.
2Is kennel cough contagious to other dogs?
Yes — kennel cough is highly contagious. It spreads through airborne droplets when an infected dog coughs, through direct nose-to-nose contact, and through shared water bowls and surfaces. An infected dog should be isolated from other dogs for at least 2 weeks after symptoms resolve. Dogs can shed the bacteria for several weeks after they stop coughing. If one dog in a multi-dog household gets kennel cough, the others will likely be exposed.
3Can a vaccinated dog get kennel cough?
Yes — the Bordetella vaccine doesn't prevent all cases of kennel cough. Kennel cough can be caused by multiple different pathogens, and the vaccine primarily targets Bordetella bronchiseptica and parainfluenza virus. Vaccinated dogs that contract kennel cough usually have milder symptoms and shorter illness duration. Think of it like the flu vaccine — it reduces severity but doesn't guarantee prevention.
4How long does kennel cough last?
Most cases of kennel cough resolve within 1-3 weeks. Mild cases often clear within 7-10 days without treatment. The cough can persist as a mild, intermittent nuisance for up to 6 weeks even after the infection has cleared — this is normal. If symptoms aren't improving after 2 weeks, or if they're getting worse (fever, thick discharge, loss of appetite), see your vet for reassessment.
5Is kennel cough dangerous for puppies?
Kennel cough can be more serious in puppies because their immune systems are still developing. Puppies are at higher risk for the infection progressing to pneumonia, which can be life-threatening. Young puppies under 6 months and those that haven't completed their vaccination series are most vulnerable. If your puppy develops a cough, see your vet promptly rather than waiting to see if it resolves on its own.
6Can kennel cough spread to humans?
Bordetella bronchiseptica can very rarely infect humans, but the risk is extremely low for healthy people. Immunocompromised individuals — those undergoing chemotherapy, with HIV, or on immunosuppressive drugs — should take precautions around dogs with active kennel cough. For the vast majority of dog owners, there's no meaningful risk of contracting kennel cough from their dog.
7Does pet insurance cover kennel cough?
Most pet insurance policies cover kennel cough diagnosis and treatment as a standard illness claim. The 14-day illness waiting period applies, which can be an issue since kennel cough often develops shortly after boarding or dog park exposure. The Bordetella vaccine is preventive care — only covered by wellness add-on plans. For mild cases costing $50-$300, the claim may not exceed your deductible. Insurance is more valuable if complications like pneumonia develop.

I'm a dog owner who got burned

My mother-in-law took her German boxer to the veterinary emergency room — $1,200 in tests, no answers. A different vet solved it in minutes with $8 pills.

That moment stuck with me. When you’re scared for your dog, you’ll pay anything. Some vets take advantage of that. I started digging into vet costs and pet insurance. The policies were confusing, the exclusions buried, the pricing impossible to compare. So I built the resource I wish existed. Real costs, real exclusions, plain speak. I’m not here to sell you a policy. I’m here so you don’t get blindsided.
