Bordetella Vaccine: At a Glance
Protects against kennel cough — not core, but essential for social dogs.
Does Your Dog Need Bordetella?
Vaccine Form
| Vaccine Form | Administration | Onset | Duration | Best For |
|---|---|---|---|---|
| Intranasal (drops) | Squirted into nose | 48-72 hours | 12 months | Most dogs — fastest protection, mucosal immunity |
| Oral (liquid) | Squirted into mouth | 2-3 days | 12 months | Dogs who hate nose drops |
| Injectable | Injection under skin | 2-4 weeks (needs booster) | 6-12 months | Dogs with nasal discharge, aggressive dogs |
Bordetella Vaccine: What to Know
| Required by virtually all boarding, daycare, and grooming facilities | |
| Intranasal form provides fastest protection (48-72 hours) | |
| Protects against Bordetella bronchiseptica — most common kennel cough cause | |
| Does NOT protect against all kennel cough pathogens (parainfluenza, adenovirus) | |
| Mild side effects: sneezing, nasal discharge (intranasal), lethargy (1-2 days) | |
| Not a core vaccine — indoor-only dogs with no social exposure may skip | |
| Vaccine prevents kennel cough 100% of the time | |
| One vaccine provides lifetime protection |
The intranasal form is preferred for most dogs — it stimulates mucosal immunity at the site of infection (the respiratory tract) and provides protection in 48-72 hours vs. 2-4 weeks for the injectable form.
Bordetella vaccine does NOT protect against all causes of kennel cough. Canine parainfluenza virus, adenovirus, and mycoplasma can also cause kennel cough. The vaccine reduces severity and duration but doesn't guarantee complete protection.
The bordetella vaccine protects against Bordetella bronchiseptica, one of several bacteria and viruses that cause kennel cough (canine infectious respiratory disease complex). It's a non-core vaccine recommended for dogs with social exposure - boarding, daycare, grooming, dog parks - and comes in injectable, intranasal, or oral forms with different timelines. Most boarding and daycare facilities require proof of vaccination within the last 6 to 12 months, not once for life.
A mild cough or sneeze for a day or two after the intranasal version is a normal, expected reaction, not a sign something went wrong.
The shot that boarding kennels ask about first
Bordetella is one piece of the kennel cough puzzle - here's which piece.
petstore.comWhere bordetella fits your dog's timeline
Before your next boarding stay
Kennel cough has more than one cause, and bordetella is just one of them
What most people call "kennel cough" is actually a cluster of respiratory pathogens - bordetella bacteria alongside viruses like canine parainfluenza and canine respiratory coronavirus - that spread easily anywhere dogs share air and surfaces. The bordetella vaccine targets that one bacterial piece specifically, which is why a vaccinated dog can still occasionally pick up a cough from a different pathogen in the same complex.
This vaccine exists because of where your dog spends time, not what breed or age they are
Any dog with regular social exposure - boarding, daycare, grooming appointments, dog parks, training classes - is a reasonable candidate, regardless of otherwise being perfectly healthy. Dogs that rarely interact with other dogs outside the household have a much lower exposure risk and may not need it at all; this is squarely a lifestyle-based, non-core vaccine.
The form your vet uses changes both the timeline and the aftercare
Injectable bordetella typically needs two initial doses a few weeks apart, then an annual booster. Intranasal and oral forms can sometimes be given as a single dose and start working faster, which matters if you're vaccinating right before a boarding stay, but they can also cause a mild, temporary cough or sneeze for a day or two afterward as a normal immune response, not a sign of infection.
Facilities set their own timing rules, and they vary
Most boarding kennels, daycares, and groomers require proof of a bordetella vaccine within the past 6 to 12 months, not a lifetime record, because protection from this vaccine doesn't last as long as core vaccines do. Always check the specific facility's requirement before booking - some want documentation within 6 months, others accept up to a year.
AAHA's canine vaccination guidelines and WSAVA's vaccination guidelines both classify bordetella as a non-core, lifestyle-based vaccine, recommended for dogs with social or boarding-type exposure rather than universally. Both describe the available forms (injectable, intranasal, oral) and note that duration of protection is shorter than core vaccines, generally requiring more frequent revaccination for dogs with ongoing exposure.
The specific 6-12 month window cited for facility requirements reflects common industry practice at boarding and daycare businesses rather than a fixed veterinary guideline number, since individual facilities set their own policies - always confirm directly with the specific facility rather than assuming a single standard applies everywhere.
Line this up with your dog's social calendar
Petstore.com's vaccine scheduler tracks bordetella's shorter renewal window separately from core vaccines, so a boarding stay never gets blocked by an expired dose.
