Kennel cough spreads fast in dog parks, daycares, and boarding facilities. The Bordetella vaccine for dogs targets one bacterial cause of that cough. Not every dog needs it.

Adult dogs that spend time around other dogs get boosters every 6 to 12 months. Puppies start as early as 3-8 weeks. At The Pet Advocate in Tracy the shot we give is an injection. It costs $30 as a walk-in, Monday through Friday from 12 to 3, with no exam fee.


Key Takeaways

  • Not every dog needs the Bordetella vaccine.
  • Adult dogs get boosters every 6 to 12 months.
  • The vaccine does not stop all kennel cough. It covers Bordetella bronchiseptica, one bacterial cause.
  • The shot we give is an injectable.

What Is Bordetella and How Does It Differ From Kennel Cough?

Bordetella bronchiseptica is a bacterium that infects a dog's respiratory tract. It is the bacterium most often involved in kennel cough, the broader syndrome also called canine infectious respiratory disease complex.

Kennel cough is a group of infections. Viruses such as parainfluenza and adenovirus-2, plus other bacteria, can produce the same honking cough, sneezing, and nasal discharge. The Bordetella vaccine protects only against that bacterium. Vaccinated dogs can still catch mild viral forms.

Bordetella spreads through airborne droplets, shared water bowls, toys, or nose-to-nose contact. Puppies, seniors, and dogs with chronic respiratory issues are more likely to get a worse cough or pneumonia.

Do All Dogs Need the Bordetella Vaccine?

No. The American Animal Hospital Association lists Bordetella as a non-core vaccine. Give it when your dog spends time around other dogs or when a boarding place requires it. See the 2022 AAHA canine vaccination guidelines.

Dogs that benefit most:

  • Board at kennels or go to daycare. Most facilities require proof of a recent vaccine.
  • Visit dog parks, groomers, training classes, or dog shows regularly
  • Live in multi-dog households or high-density areas
  • Puppies under six months and seniors with weaker immune systems

Homebody dogs that rarely meet other dogs have low risk. A fence-line chat or an occasional neighborhood walk still carries some exposure, so some owners still choose the vaccine.

Exposure risk heatmap answering “No”—AAHA lists Bordetella as non-core; boarding or daycare often required (high); parks/groomers/classes, multi-dog homes, and puppies under 6 months or seniors benefit most; occasional walks some exposure; homebody dogs low risk.


Types of Bordetella Vaccine and How They Work

The Bordetella vaccine can be given three ways. Vaccines given in the nose or mouth build protection in the nose and throat faster than an injectable.

Type How Given Onset of Protection Typical Duration Best For
Intranasal Drops or spray into the nose About 72 hours to 5 days 12 months Rapid protection before boarding
Oral Liquid squirted into the mouth About 7 days 12 months Dogs that resist nasal drops
Injectableunder the skin Shot under the skin First series: two doses 2–4 weeks apart; a current booster takes about 5 days 6–12 months Dogs that cannot tolerate a nose or mouth vaccine; the shot we give

‍

We offer the injectable Bordetella vaccine as a walk-in shot.

The shot usually makes a Bordetella infection shorter and milder, and it lowers the chance the infection turns into pneumonia.


How Often Does a Dog Need the Bordetella Vaccine?

Adult dogs receive Bordetella boosters every 6 to 12 months depending on risk. High-exposure dogs that board, go to daycare, or spend time at parks often need every 6 months because that is what the facility asks for. Low-risk dogs can stay on annual boosters. Puppies start as early as 3-8 weeks with a second dose if using injectable.

Intranasal vaccines can start at 3-4 weeks of age, though most puppies get them after 6 weeks. Injectable usually begins at 6-8 weeks, then a booster 2-4 weeks later. That timing fits the puppy vaccine schedule we use for first-year shots.

For adults, match the schedule to real risk and to the facility. Many boarding and daycare centers in California want proof from the last 6 months. The kennel chooses that six-month cutoff.

If your dog is already current on the injectable vaccine, give the booster at least 5–7 days before boarding. A dog starting the injectable vaccine for the first time needs two doses, 2 to 4 weeks apart, and is not fully protected until after the second dose.

Vaccine timeline: puppies—intranasal most after 6 weeks; injectable dose 1 around week 8, dose 2 at 2–4 weeks later; adults—high exposure every 6 months, low risk every 12 months; if current, boost at least 5–7 days before boarding.


Side Effects of the Bordetella Vaccine

Most dogs tolerate the vaccine well. Common mild reactions last 1-2 days:

  • Mild coughing, sneezing, or runny nose after the nose or mouth versions
  • Lethargy, low-grade fever, or reduced appetite
  • Soreness or a small lump at the injectable site

A 2023 JAVMA study of more than 4.6 million vaccinated dogs found adverse events after fewer than 0.2% of vaccine visits. Bordetella was one of the better-tolerated shots in that study. Serious reactions such as facial swelling, hives, or collapse are rare. Call your vet if signs worsen after 48 hours.

Safety data for pregnant dogs is limited. Discuss timing with your veterinarian if your dog is expecting.

Safety at a glance: donut chart shows under 0.2% of visits had adverse events (2023 JAVMA study of 4.6M+ vaccinated dogs); common mild reactions lasting 1–2 days—coughing/sneezing/runny nose after nose or mouth versions, lethargy or low-grade fever, soreness or small lump at injection site; call your vet if signs worsen after 48 hours.


What Does the Bordetella Vaccine Cost?

The injectable Bordetella vaccine is $30 as a walk-in, with no exam fee. Hours are Monday through Friday, 12 to 3, on our walk-in vaccine hours page.

Current prices and rates list the same $30. Other clinics often add an office exam on top of the same shot.

How to Decide: A Simple Risk Checklist

Most facilities require the Bordetella vaccine for boarding and daycare. A dog that almost never meets other dogs can skip it.

  1. Does your dog go to daycare, boarding, or group training? Most facilities require the Bordetella vaccine.
  2. Does your dog visit dog parks or play with unfamiliar dogs weekly? Parks and playdates with unfamiliar dogs count as regular exposure.
  3. Is your dog a senior, a puppy, or a dog with a history of respiratory issues? Puppies, seniors, and dogs with past respiratory trouble get sicker if they catch kennel cough.
  4. Is your dog a homebody with almost no dog contact? The Bordetella vaccine is optional. Ask your vet.
Four-question risk checklist: daycare, boarding, or group training—usually required; weekly dog parks or unfamiliar playmates—regular exposure; puppy, senior, or past respiratory issues—gets sicker if infected; homebody with almost no dog contact—optional, ask your vet.


FAQ

FAQ grid: same as kennel cough vaccine (covers Bordetella only); not always necessary—only with regular dog contact or a facility rule; shots every 6–12 months; boost 5–7 days before boarding (new dogs finish 2-dose series first); can skip with minimal exposure; skipping leaves dog susceptible (severe cases can lead to pneumonia); not a significant risk for healthy people; does not prevent all kennel cough.


Is the Bordetella vaccine the same as the kennel cough vaccine?

Yes. People call the Bordetella vaccine the kennel cough vaccine. Kennel cough is a group of infections. The shot covers Bordetella bronchiseptica. Other viruses can still cause the same honking cough.


Is the Bordetella vaccine really necessary for dogs?

No. The Bordetella vaccine is necessary only if your dog has regular contact with other dogs or if a boarding facility requires it. Many low-risk dogs skip it without problems.


How often does a dog need Bordetella shots?

Every 6-12 months. High-risk dogs that board or go to daycare often need every 6 months to satisfy facility rules. Low-risk dogs can do annual boosters.


How soon before boarding should my dog get the Bordetella vaccine?

If your dog is already current on the injectable vaccine, give the booster at least 5–7 days before boarding. A dog starting the injectable vaccine for the first time needs two doses, 2 to 4 weeks apart, and should finish that series before the stay. Confirm the facility's 6-month or 12-month rule.


Can I skip the Bordetella vaccine?

Yes. You can skip the Bordetella vaccine if your dog has minimal exposure to other dogs. Confirm any boarding or daycare requirements first, then decide with your veterinarian.


What happens if my dog doesn't get the Bordetella vaccine?

A dog that skips the Bordetella vaccine stays susceptible to Bordetella bronchiseptica and may get a worse or longer cough if exposed. Mild cases often clear with rest at home. Severe cases can progress to pneumonia, especially in puppies and seniors.


Can dogs spread Bordetella to humans?

Bordetella bronchiseptica is not a significant risk for healthy people under normal circumstances.


Does the vaccine prevent all kennel cough?

No. The Bordetella vaccine does not prevent all kennel cough. Kennel cough is a group of infections. The vaccine targets Bordetella and usually makes that infection milder. Vaccinated dogs can still get a milder cough from other viruses.
