Kennel cough is one of the most common respiratory infections in dogs, affecting millions each year. The good news: 90 percent of cases resolve on their own in 1-3 weeks without treatment. The bad news: many vets prescribe 50-100 dollars of antibiotics and cough suppressants that are unnecessary for most cases. Knowing when kennel cough needs treatment and when it will resolve on its own can save you 100-300 dollars per episode. This guide covers what kennel cough is, how to tell if your dog has it, home treatment options under 10 dollars, and when to see the vet.

What Is Kennel Cough?

Kennel cough (infectious tracheobronchitis) is a highly contagious respiratory infection caused by a combination of bacteria (Bordetella) and viruses (parainfluenza, adenovirus). It spreads through airborne droplets and direct contact — dogs catch it at boarding facilities, dog parks, grooming salons, doggy daycare, and training classes. The incubation period is 2-14 days.

Despite the name, dogs do not only catch it at kennels. Anywhere dogs congregate is a risk. Even a brief nose-to-nose contact with an infected dog at the vet’s office can transmit it.

The Classic Kennel Cough Sound

Kennel cough has a very distinctive cough that sounds like a goose honk or a dry, hacking cough followed by gagging or retching. Many owners mistake it for something stuck in the dog’s throat. The cough is triggered by excitement, exercise, pulling on the leash, and pressure on the trachea (collar pressure).

Other symptoms:

• Dry, hacking cough (the hallmark symptom)
• Gagging or retching (often producing white foam)
• Nasal discharge (usually clear and mild)
• Slight decrease in energy and appetite
• Normal temperature (under 102.5 degrees)

If the only symptom is the cough and your dog is otherwise normal — eating, drinking, active, no fever — it is almost certainly uncomplicated kennel cough that will resolve on its own.

When to See a Vet (Red Flag Symptoms)

Most kennel cough cases do not require a vet visit. But these symptoms indicate a more serious condition (pneumonia, collapsed trachea, heart disease, or foreign body) that needs immediate treatment:

• Fever above 102.5 degrees — kennel cough does not cause fever; fever indicates a secondary infection
• Lethargy or refusing to eat/drink — uncomplicated kennel cough does not cause severe lethargy
• Coughing up green or yellow mucus — indicates bacterial infection requiring antibiotics
• Difficulty breathing or rapid breathing at rest — could indicate pneumonia



• Cough that worsens after 1 week or does not improve after 2 weeks — may need antibiotics
• Symptoms in a puppy under 6 months or a senior dog over 10 — higher risk of complications
• Cough that started after a dog was choking or gagging on something — could be a foreign body obstruction

If any of these are present, see your vet. The visit (50-100 dollars) plus chest X-rays (80-150 dollars) can rule out pneumonia or other serious conditions.

Home Treatment for Kennel Cough (Under 10 Dollars)

1. Honey (3-5 Dollars)

Honey soothes the throat and reduces cough frequency. Give 1/2 to 1 tablespoon of raw honey 2-3 times daily. For small dogs (under 20 pounds), give 1 teaspoon. For large dogs (over 50 pounds), give 1 tablespoon. Most dogs eat honey willingly off a spoon. Do not give honey to puppies under 1 year (rare risk of botulism).

Alternatively, coconut oil (5-8 dollars per jar) can be used the same way — 1 teaspoon for small dogs, 1 tablespoon for large dogs, 2-3 times daily. Some dogs prefer the taste.

2. Steam Therapy (Free)

Steam moistens the airways and soothes the cough. Take your dog into the bathroom, close the door, and run a hot shower for 10-15 minutes. Do this 2-3 times daily. Your dog does not need to be in the shower — just in the steamy room. Alternatively, use a cool mist humidifier (15-25 dollars, one-time purchase) in the room where your dog sleeps.

3. Rest and Restricted Activity (Free)

The cough is triggered by excitement and exercise. Restrict activity for 1-2 weeks:

• Replace walks with short, slow potty breaks in the yard
• No running, playing, or excitement
• Use a harness instead of a collar — collar pressure on the trachea triggers coughing
• Keep your dog away from other dogs to prevent spreading the infection
• Avoid smoke, dust, and strong fragrances that irritate the airway

4. Keep Your Dog Hydrated (Free)

Drinking water soothes the throat and thins mucus. Offer water frequently. Add warm water or low-sodium chicken broth to food to increase fluid intake. Avoid dry kibble if your dog has a sore throat — soften food with warm water.

5. Vitamin C (2-3 Dollars)

Some studies suggest vitamin C supports immune function in dogs with respiratory infections. Give 100-500 mg of vitamin C (ascorbic acid) daily. Ester-C is gentler on the stomach. Do not give more than 500 mg — excess causes diarrhea.

What About Cough Suppressants?

Vets sometimes prescribe cough suppressants (hydrocodone, butorphanol) for severe coughing that prevents sleep. These cost 15-40 dollars and require a prescription. Over-the-counter human cough suppressants (dextromethorphan, Robitussin DM) can be used in some dogs at a dose of 0.5-1 mg per pound, every 8 hours — but always check with your vet first, as some human cough medicines contain ingredients toxic to dogs (xylitol, acetaminophen, pseudoephedrine).

In most cases, cough suppressants are not needed. The cough serves a purpose — clearing mucus and bacteria from the airway. Suppressing it can prolong the infection. Only use suppressants if the cough is so severe your dog cannot rest.

When Are Antibiotics Necessary?

Antibiotics (doxycycline or amoxicillin-clavulanate, 20-50 dollars for a 2-week course) are needed when:

• Symptoms worsen after 5-7 days instead of improving
• Cough produces green or yellow mucus (bacterial infection)
• Fever develops (secondary infection)
• Your dog is a puppy, senior, or immunocompromised
• Your vet diagnoses Bordetella specifically and recommends antibiotics

Most adult dogs with uncomplicated kennel cough do not need antibiotics. The infection is often viral, and antibiotics do not work on viruses. Giving antibiotics unnecessarily contributes to antibiotic resistance and wastes 20-50 dollars.

The Kennel Cough Vaccine (15-25 Dollars)

The Bordetella vaccine reduces the severity and duration of kennel cough but does not prevent it entirely (there are many strains). It is required by most boarding facilities, daycares, and training classes.

Forms:

• Intranasal — squirted into the nose. Fastest protection (48-72 hours). More effective than injectable for local immunity. May cause mild sneezing or nasal discharge for 1-2 days.
• Injectable — Given as a shot. Slower protection (7-10 days). Better for dogs that will not tolerate nose drops. Slightly less effective for local immunity but easier to administer.
• Oral — Squirted into the mouth. Similar to intranasal but less studied. Some vets offer this as an alternative.

Cost: 15-25 dollars at low-cost clinics, 25-40 dollars at full-price vets. The vaccine lasts 12 months. If your dog boards, goes to daycare, or attends training classes, the vaccine is worth the cost. If your dog stays home and rarely contacts other dogs, skip it.

The Cost of Kennel Cough: Budget vs. Typical

Home treatment saves 90-190 dollars compared to a vet visit for uncomplicated cases. The key is knowing the red flag symptoms that indicate a more serious condition requiring professional care.

Preventing Kennel Cough (Free to 25 Dollars)

• Vaccinate before boarding — Get the Bordetella vaccine 7-10 days before boarding, daycare, or training. 15-25 dollars.
• Avoid crowded dog areas during outbreaks — If you hear kennel cough is going around, skip the dog park for 2 weeks.
• Choose reputable facilities — Good boarding facilities require vaccination and have good ventilation. Ask about their kennel cough policy.
• Do not share bowls or toys — Kennel cough spreads through contaminated items. Do not let your dog share water bowls at the dog park.
• Quarantine new dogs — If you add a new dog to your household, keep them separated for 2 weeks to ensure they are not incubating kennel cough.

The Bottom Line

Kennel cough resolves on its own in 1-3 weeks in 90 percent of cases. Home treatment costs 5-10 dollars: honey for throat soothing (1/2 tablespoon 2-3 times daily), steam therapy (hot shower for 10 minutes, 2-3 times daily), rest with a harness instead of collar, and plenty of fluids. See a vet only if your dog has a fever (above 102.5), lethargy, green or yellow mucus, difficulty breathing, or the cough worsens after 1 week or does not improve after 2 weeks. Antibiotics (20-50 dollars) are needed only for secondary bacterial infections, not for the viral form. The Bordetella vaccine (15-25 dollars) reduces severity if your dog boards or goes to daycare but does not fully prevent infection. Save 100-200 dollars per episode by treating at home when symptoms are mild — and spend that money on the vaccine instead if your dog is at high risk. Most importantly, listen to the cough: the goose-honk sound is classic kennel cough. If it sounds different (wet, productive, or accompanied by wheezing), see your vet.
