Bordetella Vaccine For Dogs: Does Your Dog Need It?

If your vet has ever mentioned a "kennel cough shot" before boarding, daycare, or a grooming appointment, they were talking about the Bordetella vaccine. Unlike core vaccines every dog needs, Bordetella is considered non-core — meaning whether your dog needs it depends entirely on their lifestyle, not their age or breed.

This article is for general information only and isn't a substitute for veterinary care. Always confirm your dog's vaccine schedule with your vet based on their individual health and exposure risk.

What Is Bordetella?

Bordetella bronchiseptica is a bacterium that infects a dog's upper respiratory tract. It's one of the most common causes of kennel cough (also called infectious tracheobronchitis) — a condition where the airways become inflamed and irritated, producing a persistent, dry, honking cough that can sound alarming even though most cases are mild.

How Kennel Cough Spreads

Kennel cough spreads easily through the air and through direct contact — a cough, a sneeze, shared water bowls, or even toys can pass it between dogs. This is why it moves quickly through places where dogs gather in close quarters: boarding kennels, daycare centers, grooming salons, dog parks, and training classes. A dog doesn't need direct nose-to-nose contact to catch it — sharing the same space for even a short time can be enough.

Does My Dog Actually Need This Vaccine?

This is the real question most owners are trying to answer, and the honest response is: it depends on your dog's lifestyle.

Your dog likely needs it if they:

Attend daycare, boarding, or grooming regularly
Visit dog parks or group training classes
Compete in shows, sports, or other events with other dogs
Live in a household with multiple dogs who go in and out of the home often

Your dog may not need it if they:

Rarely interact with other dogs outside your household
Don't attend boarding, daycare, or grooming facilities
Live a mostly low-contact, at-home lifestyle

Many boarding and daycare facilities actually require proof of Bordetella vaccination before accepting a dog, regardless of how low-risk their lifestyle otherwise is — so it's worth checking requirements ahead of any planned boarding.

How the Vaccine Is Given

Vets can administer the Bordetella vaccine in three different ways, and the method can affect how quickly it takes effect:

Intranasal — Given as drops in the nose. This route builds local immunity right where the infection typically enters, and often provides protection faster than injectable forms — sometimes within 72 hours.

Oral — A liquid given by mouth, offering a similar quick-acting option for dogs who don't tolerate nasal administration well.

Injectable — Given as a shot, typically requiring two doses a few weeks apart for initial protection, with annual boosters afterward.

Your vet will recommend the best option based on your dog's temperament, health history, and how soon they need protection (for example, before a boarding stay booked in the next few days).

Side Effects & What's Normal

Like most vaccines, Bordetella can cause mild, short-lived side effects. These are generally nothing to worry about:

Mild lethargy or low energy for 24-48 hours
A low-grade fever shortly after vaccination
Mild sneezing or nasal discharge (with intranasal/oral forms)
Slight swelling or tenderness at the injection site (with the injectable form)

Contact your vet if you notice:

Facial swelling, hives, or difficulty breathing
Repeated vomiting
Severe lethargy lasting more than 2 days
A cough that develops and doesn't improve within a few days (in rare cases, dogs can develop mild symptoms from the vaccine itself, especially with intranasal forms)

Serious reactions are uncommon, but any dog with a history of vaccine reactions should be monitored closely and discussed with your vet beforehand.

Cost & How Often It's Needed

Bordetella vaccination is generally inexpensive compared to other veterinary care, though exact pricing varies by clinic, location, and administration method. Most dogs need:

Initial vaccination, sometimes followed by a booster a few weeks later (particularly for injectable forms in first-time recipients)
Annual boosters for ongoing protection — though some facilities require boosters every 6 months for high-exposure dogs

If your dog needs it primarily for a specific event like boarding, plan ahead — the vaccine needs time to become effective, so getting it done at least a few days to a week before exposure is generally recommended.

Frequently Asked Questions

Can vaccinated dogs still get kennel cough? Yes. Like many vaccines, Bordetella reduces the risk and severity of illness but doesn't guarantee complete protection, since kennel cough can be caused by several different bacteria and viruses working together. A vaccinated dog who still gets sick typically experiences a milder, shorter illness than an unvaccinated dog.

Is the Bordetella vaccine required by boarding facilities? Many are, yes — it's one of the most commonly required vaccines for boarding, daycare, and grooming facilities, often alongside proof of rabies and distemper vaccination. Check with your specific facility well before your dog's visit.

Can puppies get this vaccine? Yes, depending on the form — some intranasal and oral versions can be given to puppies as young as 3 weeks old, though timing depends on your vet's specific protocol and your puppy's overall vaccine schedule.
