Can Humans Catch Kennel Cough? Expert Insights on Cross-Species Transmission
If your beloved furry friend has recently developed that distinctive hacking cough, you’re probably wondering: can I catch kennel cough from my dog? It’s a question that worries many pet parents, especially those with young children or elderly family members at home. The good news? We’ve got the definitive answer backed by veterinary expertise and scientific evidence.
Kennel cough, medically known as canine infectious tracheobronchitis, is one of the most common respiratory conditions affecting dogs worldwide. This highly contagious illness spreads rapidly through dog populations, particularly in boarding facilities, dog parks, and shelters. But here’s what you really need to know: the relationship between kennel cough and human health is far more nuanced than a simple yes or no answer.
In this comprehensive guide, we’ll explore the science behind kennel cough transmission, examine whether humans are actually at risk, and provide practical strategies for protecting your household when your dog comes down with this pesky condition.
What Is Kennel Cough?
Kennel cough is essentially the canine equivalent of the common cold in humans, though it can occasionally develop into something more serious. The condition is typically caused by a combination of viral and bacterial pathogens, with Bordetella bronchiseptica and canine parainfluenza virus being the primary culprits. Think of it as a perfect storm of respiratory irritation that causes significant inflammation in your dog’s airways.
The condition earned its distinctive name because it spreads like wildfire in kennels and boarding facilities where dogs are housed in close quarters. However, dogs can contract kennel cough anywhere—at dog parks, during grooming sessions, or even from a neighbor’s pup during a casual walk. The virus and bacteria thrive in environments with poor ventilation and high dog density.
Most cases are self-limiting, meaning they resolve on their own within 1-3 weeks without treatment. However, some dogs—particularly puppies, senior dogs, or those with compromised immune systems—may experience more severe symptoms or secondary infections.
How Kennel Cough Spreads
Understanding transmission is crucial to answering our main question. Kennel cough spreads through respiratory droplets when infected dogs cough, sneeze, or bark. These tiny droplets can travel through the air and land on surfaces, or they can be inhaled directly by another dog in close proximity. The pathogens can also survive on contaminated objects like food bowls, toys, and bedding.
The incubation period typically ranges from 2-14 days, meaning an infected dog might not show symptoms immediately after exposure. This delayed onset is why kennel cough can spread so effectively—infected dogs may be contagious before owners even realize their pup is sick. If you’re wondering about other respiratory conditions, you might also want to explore whether dogs can get the flu, as symptoms can sometimes overlap.
Dogs shed the bacteria and virus primarily through respiratory secretions, making close contact the most common transmission route. However, the pathogens are relatively fragile outside the body and don’t survive long on environmental surfaces—typically only a few hours to days depending on conditions.
Can Humans Actually Catch Kennel Cough?
Here’s the straightforward answer that most pet parents want to hear: No, humans cannot catch kennel cough from dogs. The specific pathogens responsible for kennel cough in canines are species-specific, meaning they’ve evolved to infect dogs and don’t have the biological machinery to infect human respiratory cells.
The primary bacterial culprit, Bordetella bronchiseptica, is indeed found in humans occasionally, but it causes disease in humans only under very specific circumstances—typically in immunocompromised individuals or those with severe underlying lung disease. Even then, human infection is extraordinarily rare and would not be acquired from casual contact with an infected dog. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), there are no documented cases of kennel cough transmission from dogs to humans in typical household settings.
The canine parainfluenza virus, another common component of kennel cough, is completely distinct from human parainfluenza viruses. While humans do have our own parainfluenza viruses that cause respiratory illness, they are genetically different and don’t cross species barriers. This is a fundamental principle in virology: viruses are highly specialized and generally cannot infect species outside their evolutionary history.
If you’re curious about disease transmission between species, you might find it interesting to learn about whether dogs can catch human colds, which demonstrates how this biological incompatibility works both ways.
Symptoms and Timeline in Dogs
While humans are safe from kennel cough, your dog certainly isn’t. Recognizing the symptoms early can help you seek appropriate care and prevent spread to other dogs. The classic sign is a persistent, dry, hacking cough that sounds like your dog is trying to clear something from their throat—some owners describe it as a honking sound.
Common symptoms include:
- Dry, persistent cough (often worse during excitement or exercise)
- Gagging or retching, sometimes followed by clear mucus
- Sneezing and nasal discharge
- Mild fever (though many dogs maintain normal temperature)
- Lethargy and decreased appetite
- Watery eyes
The timeline typically follows this pattern: After exposure, your dog enters the incubation period (2-14 days) with no symptoms. Once symptoms appear, the cough usually peaks around day 5-7 and gradually improves over the following weeks. Most dogs recover completely within 3 weeks, though some may have a lingering cough for longer.

It’s important to note that while kennel cough is usually mild, it can occasionally progress to more serious conditions like pneumonia, especially in vulnerable dogs.
Protecting Your Family
Since humans can’t catch kennel cough from dogs, your primary concern should be preventing spread to other dogs rather than protecting yourself. However, good hygiene practices are always wise and can prevent transmission of other pathogens.
Here are practical steps to minimize risk:
- Wash your hands regularly after handling your sick dog, especially before touching your face or preparing food. While kennel cough won’t infect you, other bacteria and viruses can transfer.
- Keep your dog isolated from other dogs for at least 2-3 weeks or until your vet confirms they’re no longer contagious. This is critical for preventing spread to vulnerable pets.
- Clean and disinfect toys, bowls, and bedding regularly. Use a pet-safe disinfectant and wash items in hot water when possible.
- Avoid dog parks and group activities until your dog has fully recovered. This is a matter of courtesy to other dog owners.
- Cover your dog’s cough when in public by keeping them away from other dogs entirely.
- Maintain good ventilation in your home, which helps clear respiratory particles and benefits everyone’s health.
Interestingly, the transmission dynamics are similar to how dogs can catch colds from humans—proper hygiene and isolation are your best tools regardless of the direction of potential transmission.
Treatment and Recovery
Since kennel cough is typically viral in origin, antibiotics aren’t usually necessary unless a secondary bacterial infection develops. Your veterinarian will likely recommend supportive care to help your dog feel more comfortable during recovery.
Common treatment approaches include:
- Cough suppressants to reduce the frequency and severity of coughing, providing relief and allowing your dog to rest better
- Rest and isolation to allow the immune system to fight the infection without additional stress
- Humidification using a humidifier or steam from a bathroom to help soothe irritated airways
- Soft, easily digestible food to maintain nutrition without irritating the throat
- Plenty of fresh water to keep mucous membranes moist and support immune function
- Antibiotics only if secondary bacterial infection is suspected or confirmed
Your vet might also recommend proper ear cleaning and hygiene to prevent secondary ear infections, which can occasionally develop alongside respiratory illness. Most dogs recover fully without complications within 2-3 weeks, though some may have a lingering cough for up to 8 weeks.
Prevention Is Key
The best way to handle kennel cough is to prevent it in the first place. Vaccination is your most effective tool, though it’s important to understand that kennel cough vaccines don’t guarantee complete immunity—they significantly reduce the severity and duration of illness if exposure occurs.
Prevention strategies include:
- Vaccination – The kennel cough vaccine is available as an intranasal spray, oral, or injectable form. The American Kennel Club (AKC) recommends vaccination for dogs with regular social contact with other dogs.
- Avoid high-risk environments when possible, particularly if your dog is unvaccinated, very young, elderly, or immunocompromised.
- Maintain good hygiene at home and during outings, including regular handwashing after touching other dogs.
- Choose reputable boarding facilities that maintain strict hygiene protocols and require vaccination records.
- Keep your dog’s immune system strong through proper nutrition, exercise, and regular veterinary care.
- Minimize stress, which can compromise immune function and make dogs more susceptible to infection.
If you’re concerned about your dog’s respiratory health in general, understanding the differences between conditions like whether cats can catch kennel cough from dogs can help you appreciate how species-specific these conditions truly are.
According to UC Davis School of Veterinary Medicine, vaccination reduces the incidence of kennel cough by approximately 80% in vaccinated populations, making it a worthwhile preventive measure for social dogs.
Frequently Asked Questions
Can I catch kennel cough from my dog?
No. Kennel cough is caused by pathogens that are species-specific to dogs. Humans cannot contract kennel cough from infected dogs through any casual contact. The bacteria and viruses involved have not evolved to infect human respiratory cells.
What if I have a weakened immune system?
Even immunocompromised individuals cannot catch kennel cough from dogs. While some individuals with severe immune deficiencies might be more susceptible to certain bacterial infections, kennel cough specifically is not a concern. However, you should still practice good hygiene around your sick dog and consult your physician if you have specific health concerns.
Can my family members catch it from me if I’ve been around the dog?
No. Since humans cannot catch kennel cough, you cannot transmit it to other family members. The pathogens don’t survive in or on the human body.
How long is my dog contagious?
Dogs are typically contagious for 1-3 weeks after symptoms appear, though some may shed pathogens for up to 6 weeks. Your veterinarian can give you a more specific timeline based on your dog’s condition and treatment response.
Should I be concerned about my other pets?
Yes, if you have other dogs, they are at risk of catching kennel cough from your infected dog. Cats are much less susceptible, though they can occasionally catch it. Keep infected dogs isolated from other pets when possible.
When should I call the vet?
Contact your veterinarian if your dog shows signs of kennel cough, especially if your dog is very young, elderly, or has underlying health conditions. Seek emergency care if your dog has difficulty breathing, shows signs of pneumonia (lethargy, fever, loss of appetite), or the cough persists beyond 3 weeks.
Does my dog need antibiotics?
Most cases of kennel cough are viral and don’t require antibiotics. However, your vet may prescribe antibiotics if there’s evidence of secondary bacterial infection or if your dog is at high risk for complications.
Can kennel cough become serious?
While most cases are mild and self-limiting, kennel cough can occasionally progress to pneumonia or other serious conditions, particularly in puppies, senior dogs, or immunocompromised individuals. This is why veterinary evaluation is important.
