Here's Why the Bordetella Vaccine Is So Important
Bordetella, also known as kennel cough, is one of the most common respiratory infectious diseases in dogs. But the bordetella vaccine makes it possible to limit your dog’s risk of getting sick.
When dogs hang out together, bordetellosis—more commonly called kennel cough—can take hold. Your veterinarian may have already mentioned the necessity of giving your dog a Bordetella vaccine before you can bring her in for boarding. Any place where dogs are in contact with other pups—like kennels, dog shows, doggy daycare, and dog parks—can be a place where kennel cough is transmitted. But there is a solution that can help keep your dog healthy: the Bordetella vaccine.
What Is Bordetella?
One of the most common respiratory infectious diseases in dogs, bordetellosis, is caused by a bacteria called Bordetella bronchiseptica, which invades the lung tissues. It is spread by aerosolized spray from a dog’s mouth or nose. Bordetellosis is a form of infectious tracheobronchitis and is related to whooping cough in people, caused by a different species of Bordetella known as Bordetella pertussis.
The most common sign of bordetella in dogs is in the infection’s alternate name—kennel cough. “Kennel cough is characterized by coughing and upper respiratory signs,” says Kathryn Primm, DVM, of Applebrook Animal Hospital in Ooltewah, Tenn.
The cough is often characterized as loud and harsh, as the dog’s lungs try to clear themselves of a build-up of phlegm as the infection spreads within the respiratory tract. Because the virus harms the respiratory tract, other bacteria can have an easier time invading as well. “This disease is a complex of many causative agents,” Primm says.
But note that some infected dogs are asymptomatic, and show no signs of infection at all. That’s why it’s so important to ensure all dogs are vaccinated before boarding or prolonged closeness with other dogs, to help make sure bordetellosis doesn’t have a chance to set in and make a dog sick.
If an infection does take hold in a dog’s lungs, bordetellosis treatment by your veterinarian might include a prescription antibiotic to help fight those other bacterial irritants that can make the infection even worse. Your vet may also recommend rest and minimal exercise as your dog recovers, since the coughing can be exacerbated by exercise or stimulation of the throat.
When Should My Dog Get the Bordetella Vaccine?
Bordetella vaccines can be delivered in three different ways, and the best time to start inoculation prevention can vary, as listed by guidelines from the American Animal Hospital Association:
- Two skin injections 2 to 4 weeks apart; can start injection series at 8 weeks of age
- A single administration into the nose; can start at 3 or 4 weeks of age
- A single oral administration between the gums and the inner cheek; can start at 8 weeks of age
Talk to your veterinarian about their preferred method of delivery. Primm says her practice uses the intraoral Bordetella vaccination—through the dog’s mouth—because it tends to be better tolerated by the pup. She adds, “I think that the most effective vaccine is the one that you can actually get into the pet!”
After their initial dose of the vaccine, dogs should then receive a booster injection once a year to maintain protection against infection.
Are There Any Risks of Giving My Dog the Bordetella Vaccine?
“In my experience, the vaccine is safe and well-tolerated,” Primm says. “Like any vaccine, it is not 100 percent effective against all coughs, so owners cannot expect an ‘easy button’ that will always protect from every kind of cough and it must be kept current per the guidelines and your veterinarian’s recommendation.”
Taking measures to protect your dog from the respiratory disease bordetellosis is nothing to cough at. Be sure to talk with your vet to make sure your dog is up to date on her Bordetella booster, too—which is typically required every year at your annual visit.
