If you’ve ever hesitated to board your dog because you heard about "kennel cough," this guide is for you. Kennel cough is real, it is contagious, and any responsible boarding or daycare owner takes it seriously. But it is also usually mild, highly preventable, and no reason to avoid boarding your dog at a facility that does things right. Here is the honest, no-scare-tactics explanation of what it is and how the right precautions protect your dog.
What kennel cough actually is
Kennel cough is the common name for canine infectious tracheobronchitis — an inflammation of the airways caused by several bacteria and viruses, most often Bordetella bronchiseptica. The hallmark sign is a persistent, dry, honking cough, sometimes ending in a gag. In most healthy dogs it is the canine equivalent of a chest cold: uncomfortable for a week or two, then resolved. It becomes more serious mainly in very young puppies, seniors, or dogs with other health problems, which is why prevention matters.
How it spreads
It is airborne and spreads through respiratory droplets when dogs cough, as well as through shared surfaces and close contact. Any place dogs gather — boarding, daycare, grooming, dog parks, even the vet’s waiting room — carries some risk, just as any place people gather carries some risk of a cold. The name "kennel cough" unfairly singles out boarding, but a dog is just as likely to catch it at a busy dog park.
The vaccine that protects against it
The Bordetella vaccine significantly reduces the risk and severity of kennel cough, which is exactly why reputable boarding and daycare facilities require it. No vaccine is 100% — kennel cough has multiple causes — but a vaccinated dog is far better protected, and requiring it across all guests dramatically lowers the chance of an outbreak. If a facility does not require Bordetella, that is a red flag.
How a good facility prevents it
Vaccine requirements are the foundation, but how a facility operates matters just as much. Animal Friends Pet Care requires current Rabies, DHPP, and Bordetella for every boarding and daycare guest, with no exceptions. Beyond that, our practices are built around minimizing disease spread: we never mix unfamiliar dogs unsupervised, outdoor time is one dog at a time, every dog has its own private suite rather than a shared kennel, and we keep the facility clean. Good ventilation, sanitation, and separation are how a careful facility keeps respiratory illness from spreading.
What to do if your dog gets it
If your dog develops a honking cough after any group setting, keep them home and away from other dogs, and call your vet. Most cases resolve with rest and time; your vet will advise whether anything more is needed and rule out more serious causes. Let your boarding or daycare facility know, too — a responsible operator wants to know so they can watch for any other cases. Catching it early and keeping a coughing dog away from others is how outbreaks are contained.
