Ever heard that hacking cough from your dog? It might be kennel cough, and a sneaky bacteria called Bordetella bronchiseptica is often the culprit. While not the only cause, Bordetella irritates the airways, triggering that honking cough. While usually mild, kennel cough can be uncomfortable for our furry friends. Luckily, vaccinations can shield them from Bordetella and other common canine cough triggers. Talk to your vet to see if the kennel cough vaccine is right for your pup!
