Yes, there is a vaccine for kennel cough, and it’s one of the most commonly administered dog vaccines in the world. It primarily targets Bordetella bronchiseptica, the bacterium most responsible for the harsh, honking cough that gives the illness its name. The vaccine comes in three forms: a nasal spray, an oral liquid, and a traditional injection. While it doesn’t guarantee your dog will never cough, it significantly reduces the severity and likelihood of illness.
What the Vaccine Covers
Kennel cough isn’t caused by a single germ. It’s actually a syndrome called canine infectious respiratory disease complex (CIRDC), involving a mix of bacteria and viruses that can infect a dog simultaneously. The kennel cough vaccine targets the two most common culprits: Bordetella bronchiseptica bacteria and canine parainfluenza virus. Most intranasal vaccines bundle both into a single dose.
Several other pathogens can also cause the same coughing illness, including canine respiratory coronavirus, canine herpesvirus, Mycoplasma bacteria, and Streptococcus zooepidemicus. No routine kennel cough vaccine covers these. This is the main reason a vaccinated dog can still develop symptoms, and it’s worth knowing so you’re not caught off guard if it happens.
Three Ways the Vaccine Is Given
The intranasal version is the most widely used. A small syringe delivers half a milliliter of liquid into each nostril. It stimulates a rapid immune response right at the mucosal surface where infections take hold first. Studies show it can offer protection within 48 to 72 hours, making it the fastest-acting option.
The oral version works similarly. One milliliter of liquid is squirted into the cheek pouch. It’s a good alternative for dogs that don’t tolerate anything near their nose, and it’s the recommended backup for shelter dogs when a nasal spray isn’t feasible. Both the nasal and oral vaccines require only a single dose to immunize.
The injectable version is a traditional shot given under the skin. It requires two doses spaced two to four weeks apart for the initial series, and protective immunity doesn’t kick in until at least five days after that second injection. This makes it the slowest to take effect and means more planning if you’re vaccinating ahead of boarding or daycare.
Is It Required?
Veterinary guidelines classify the Bordetella vaccine as “noncore,” meaning it’s not recommended for every dog the way rabies or distemper vaccines are. It’s intended for dogs whose lifestyle puts them at risk: those who visit boarding facilities, doggy daycare, grooming salons, dog parks, or training classes. In practice, most boarding kennels, groomers, and daycares require proof of vaccination before they’ll accept your dog.
For shelter dogs, the calculus is different. The World Small Animal Veterinary Association recommends treating respiratory vaccines as core for any dog entering a shelter environment, given how quickly infections spread in close quarters. Shelters typically vaccinate every dog on intake.
How Well It Works
A comprehensive review of clinical studies spanning nearly four decades found that intranasal, injectable, and oral Bordetella vaccines all reduce disease severity and limit bacterial growth in the airways. Vaccinated dogs that do get exposed tend to cough less, recover faster, and shed fewer bacteria to other dogs.
That said, the vaccine is not a perfect shield. Because kennel cough involves multiple pathogens and only two are covered by the standard vaccine, breakthrough infections happen. Think of it less like a brick wall and more like a seatbelt: it won’t prevent every injury, but it dramatically reduces the worst outcomes. Dogs in high-exposure environments benefit the most.
Timing for Boarding or Daycare
If your dog needs the vaccine before boarding, timing matters. The intranasal and oral vaccines work fastest, with protection building within two to three days of a single dose. The injectable form is much slower, requiring two shots over several weeks plus at least five days after the second dose before immunity develops.
Most boarding facilities ask for proof of vaccination at least a few days to two weeks before check-in. Call ahead to find out their specific policy. If you’re scrambling last minute, the intranasal vaccine gives you the tightest window, but even then, same-day vaccination and drop-off isn’t ideal.
Puppy Vaccination Schedule
Puppies can receive the intranasal vaccine remarkably early, with some products approved for use at just three weeks of age. The oral vaccine is typically approved starting at seven or eight weeks. Both need only a single dose for the initial series. The injectable version also starts around that age range but requires two doses given two to four weeks apart.
One advantage of the nasal and oral vaccines for puppies is that maternal antibodies, the protective proteins passed from mother to pup, don’t interfere with them. Injectable vaccines can sometimes be partially neutralized by lingering maternal immunity, which is why they require the two-dose series.
After the initial vaccination, boosters are recommended annually for dogs that remain at risk. Some facilities or veterinarians recommend every six months for dogs with very high exposure, such as those in regular daycare.
Side Effects
The kennel cough vaccine is generally well tolerated. The most common reaction is mild lethargy and low-grade fever lasting a day or two. Dogs that receive the nasal spray often develop temporary cold-like symptoms: sneezing, a runny nose, and occasionally a mild cough. These are normal responses to the live vaccine contacting the nasal lining and typically resolve within 24 to 48 hours.
Dogs that get the injectable form may develop a small, firm bump at the injection site along with some tenderness or stiffness in the area. This is a standard reaction to any injection and usually fades on its own. Serious allergic reactions are rare but possible with any vaccine.
What It Costs
The Bordetella vaccine is one of the more affordable routine veterinary expenses. In 2025, a single dose typically runs between $19 and $60, depending on your location, the clinic, and which formulation is used. Low-cost vaccination clinics at pet stores or community events often charge on the lower end of that range. If your dog needs the injectable version, you’ll pay for two doses to complete the initial series.
