How Long is Kennel Cough Contagious After Starting Antibiotics?
While antibiotics help treat the bacterial components of kennel cough, they don’t immediately eliminate the viral ones. Therefore, even after starting antibiotics, a dog with kennel cough can remain contagious for several days, typically around 3-7 days, or until all symptoms have completely resolved.
Understanding Kennel Cough
Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory disease affecting dogs. It’s often compared to the common cold in humans. While typically not life-threatening, it can be quite uncomfortable for your canine companion. The name comes from its rapid spread in environments where dogs are kept in close proximity, such as kennels, shelters, and dog parks.
What Causes Kennel Cough?
Kennel cough isn’t caused by a single pathogen; it’s usually a complex of viruses and bacteria. Common culprits include:
- Bordetella bronchiseptica (a bacterium)
- Canine parainfluenza virus
- Canine adenovirus
- Canine distemper virus
- Canine influenza virus
These pathogens attack the lining of the trachea (windpipe) and bronchi (airways), making the dog more susceptible to secondary infections.
Symptoms of Kennel Cough
Recognizing the symptoms early is crucial for prompt treatment and preventing further spread. Common signs include:
- A persistent, dry, hacking cough (often described as a “goose honk”)
- Retching or gagging
- Nasal discharge
- Lethargy
- Fever (in some cases)
The severity of symptoms can vary depending on the dog’s age, overall health, and the specific pathogens involved.
Treatment Options for Kennel Cough
Treatment for kennel cough typically focuses on relieving symptoms and preventing secondary infections. This often involves:
- Antibiotics: Primarily used to combat Bordetella bronchiseptica and other bacterial infections. While antibiotics don’t directly address viral components, they are frequently prescribed to prevent secondary infections.
- Cough suppressants: To provide relief from the persistent coughing, especially at night. Always consult your veterinarian before administering cough suppressants.
- Bronchodilators: To help open up the airways and make breathing easier, particularly if the dog has underlying respiratory issues.
- Rest and supportive care: Ensuring the dog is well-hydrated, fed a nutritious diet, and allowed to rest in a comfortable environment.
The Role of Antibiotics in Contagiousness
While antibiotics are an important part of kennel cough treatment, it’s vital to understand that they primarily target bacterial infections. Viral components of the disease can persist, making the dog contagious even while on antibiotics. This is why it’s crucial to isolate your dog even after starting medication. How long is kennel cough contagious after starting antibiotics? As mentioned, it’s typically 3-7 days, or until all symptoms subside.
Factors Affecting Contagious Period
Several factors can influence how long is kennel cough contagious after starting antibiotics:
- Severity of infection: Dogs with more severe infections may remain contagious for a longer period.
- Specific pathogens involved: Different viruses and bacteria have varying incubation and shedding periods.
- Dog’s immune system: A dog with a stronger immune system may clear the infection more quickly.
- Underlying health conditions: Dogs with pre-existing health problems may take longer to recover and remain contagious for longer.
- Compliance with medication: Properly administering prescribed medication as directed significantly impacts recovery time and contagiousness.
Preventing the Spread of Kennel Cough
Prevention is always better than cure. Several measures can help prevent the spread of kennel cough:
- Vaccination: Vaccinate your dog against common kennel cough pathogens like Bordetella bronchiseptica and canine parainfluenza virus.
- Avoid crowded areas: Limit your dog’s exposure to areas where many dogs congregate, such as dog parks and boarding facilities, especially during outbreaks.
- Good hygiene: Practice good hygiene by washing your hands after handling other dogs.
- Quarantine: If your dog is diagnosed with kennel cough, isolate them from other dogs to prevent further spread.
- Proper ventilation: Ensure adequate ventilation in kennels and other areas where dogs are housed together.

Frequently Asked Questions About Kennel Cough Contagiousness
How soon will antibiotics stop my dog from coughing if they have kennel cough?
Antibiotics specifically target the bacterial component of kennel cough, such as Bordetella bronchiseptica. You may notice an improvement in symptoms within 2-3 days of starting antibiotics, but the cough might not completely disappear immediately. Viral infections, if present, will take longer to resolve.
Can I still take my dog to the dog park after they’ve started antibiotics for kennel cough?
No. Even though your dog is on antibiotics, they are still potentially contagious. Isolating your dog is crucial to prevent the spread of kennel cough to other susceptible dogs. Continue to avoid dog parks, boarding facilities, and other areas where dogs congregate until your veterinarian gives you the all-clear.
My dog seems better after only one day of antibiotics. Can I stop the medication?
It’s extremely important to complete the entire course of antibiotics prescribed by your veterinarian, even if your dog seems to be feeling better. Stopping early can lead to antibiotic resistance and a recurrence of the infection.
How can I disinfect my home environment to prevent reinfection or spread to other pets?
Thorough cleaning with a disinfectant effective against bacteria and viruses is essential. Focus on areas where your dog spends time, such as bedding, bowls, and toys. Use a diluted bleach solution (1:32 ratio of bleach to water) or a commercial disinfectant labeled for use against canine pathogens. Ensure all surfaces are thoroughly rinsed after disinfection.
Are there any natural remedies that can help my dog recover from kennel cough faster?
While natural remedies may provide some supportive care, they should not replace veterinary treatment. Honey can soothe a sore throat and reduce coughing, and humidifiers can help to loosen congestion. Consult your veterinarian before using any natural remedies, especially if your dog is already on medication.
Is kennel cough contagious to humans or other animals besides dogs?
Most kennel cough pathogens are species-specific and do not typically infect humans. However, Bordetella bronchiseptica can, in rare cases, infect individuals with weakened immune systems. Cats and other animals can also contract Bordetella, but it’s often a different strain than what affects dogs. Consult with both your veterinarian and your own doctor if you have concerns.
What happens if kennel cough is left untreated?
If left untreated, kennel cough can progress to more serious conditions such as pneumonia, especially in puppies, elderly dogs, or dogs with compromised immune systems. Early diagnosis and treatment are crucial to prevent complications.
My dog was vaccinated against kennel cough. Why did they still get it?
The kennel cough vaccine typically covers the most common pathogens, such as Bordetella bronchiseptica and canine parainfluenza virus. However, it doesn’t protect against all possible causes of kennel cough. Even vaccinated dogs can still contract the disease, but they typically experience milder symptoms.
How soon after exposure to a dog with kennel cough will my dog show symptoms?
The incubation period for kennel cough can range from 2 to 14 days. This means your dog may not show symptoms immediately after exposure. Keep a close eye on your dog and consult your veterinarian if you notice any signs of respiratory illness.
If I have multiple dogs, should I treat them all if one dog is diagnosed with kennel cough?
It’s best to consult with your veterinarian. They can assess each dog’s individual risk and determine the appropriate course of action. Prophylactic treatment may be recommended for dogs who have been in close contact with the infected dog.
My dog’s cough seems to be getting worse, even with antibiotics. What should I do?
Contact your veterinarian immediately. A worsening cough despite antibiotics may indicate a secondary infection or another underlying issue. Your veterinarian may need to adjust the treatment plan.
What are the long-term effects of kennel cough?
In most cases, dogs recover fully from kennel cough without any long-term effects. However, severe or untreated cases can lead to chronic bronchitis or other respiratory problems. Follow your veterinarian’s recommendations for treatment and aftercare to ensure a complete recovery. Remember that How long is kennel cough contagious after starting antibiotics? depends significantly on the severity and the dog’s individual health.
