If your dog goes to daycare, boarding, grooming, training classes, or spends a lot of time around other dogs, you have probably heard of the Bordetella vaccine.
Many owners simply know it as the “kennel cough vaccine.” But that name can be a little misleading.
Bordetella bronchiseptica is one of several organisms that can contribute to canine infectious respiratory disease complex, often called kennel cough. Other viruses and bacteria can also be involved, which means a Bordetella vaccine does not guarantee that a dog will never develop a cough after being around other dogs.
Still, for dogs with regular exposure to other dogs, vaccination can be an important part of reducing risk.
So how often does a dog actually need a Bordetella vaccine? Does every dog need one? And why do some daycare or boarding facilities ask for it more often than others?
Here is what dog owners should know.
What Is Bordetella?
Bordetella bronchiseptica is a bacterium that can infect a dog’s respiratory tract.
It is commonly associated with canine infectious respiratory disease complex, or CIRDC. You may also hear this group of illnesses called kennel cough.
Dogs can spread Bordetella through respiratory droplets when they cough or sneeze, through direct contact with other dogs, and through contaminated objects such as bowls or toys. Dogs that spend time in close-contact environments are at greater risk of exposure.
Common higher-risk situations include:
- Dog daycare
- Boarding kennels
- Grooming facilities
- Dog parks
- Training classes
- Dog shows or competitions
- Animal shelters
- Other environments where many dogs share the same space
This is why many boarding and daycare facilities ask for proof of Bordetella vaccination before allowing a dog to enter.
Is the Bordetella Vaccine Required for Every Dog?
Not necessarily.
AAHA classifies Bordetella as a noncore vaccine, meaning it is generally recommended based on a dog’s lifestyle and exposure risk rather than automatically for every dog.
A dog that rarely interacts with other dogs may have a very different level of risk from a dog attending daycare several times a week.
That is why your veterinarian may ask questions such as:
Does your dog go to daycare?
Do you board your dog when you travel?
Does your dog regularly visit dog parks?
Does your dog attend training classes or grooming appointments?
Will your dog be staying somewhere with many unfamiliar dogs?
The answers help your veterinarian decide whether Bordetella vaccination makes sense for your dog.
What Is the Typical Bordetella Vaccine Schedule?
This is where owners often get confused because the schedule depends partly on which type of Bordetella vaccine is used.
Bordetella vaccines may be given:
- Intranasally, through the nose
- Orally, inside the mouth
- By injection under the skin
According to AAHA guidance, intranasal and oral Bordetella vaccines can generally be given as a single initial dose.
Injectable Bordetella vaccines may require two initial doses given 2 to 4 weeks apart, depending on the product and the dog’s vaccination history.
After the initial vaccination series, AAHA lists annual revaccination for dogs that remain at risk.
However, the exact schedule should follow the specific vaccine product and your veterinarian’s recommendation.
So Does My Dog Need Bordetella Every 6 Months or Every Year?
You may have noticed that your veterinarian says once a year while a boarding facility asks for vaccination within the last six months.
That does not necessarily mean either one is wrong.
Veterinary vaccination recommendations and facility admission policies are not always the same thing.
AAHA’s general guidance includes annual revaccination for at-risk dogs, but an individual boarding, daycare, grooming, or training facility may set its own health requirements based on how closely dogs interact in that environment.
Before scheduling a vaccination solely for daycare or boarding, it is worth asking the facility exactly what documentation they require.
For example:
“How recent does the Bordetella vaccine need to be?”
“Do you accept oral, intranasal, and injectable vaccines?”
“Does my dog need to wait after vaccination before attending?”
That last question can be particularly important if you are vaccinating right before a trip or daycare start date.
How Quickly Does the Bordetella Vaccine Work?
There is not one universal answer because Bordetella vaccines come in different formulations and are administered in different ways.
Intranasal vaccines are designed to stimulate immunity directly in the respiratory tract, and AAHA notes that the intranasal route is generally preferred for respiratory pathogens when it can be used appropriately.
But owners should not assume that giving a vaccine immediately before boarding means their dog is instantly protected.
If you know your dog will be boarding or starting daycare, discuss timing with your veterinarian and check the facility’s requirements ahead of time rather than waiting until the day before.
Can a Vaccinated Dog Still Get Kennel Cough?
Yes.
This is one of the most important things to understand about Bordetella vaccination.
“Kennel cough” is not caused by a single pathogen.
Canine infectious respiratory disease can involve Bordetella bronchiseptica, parainfluenza virus, adenovirus, Mycoplasma and other respiratory pathogens. Cornell describes it as a collection of respiratory diseases rather than one single infection.
So a dog can be vaccinated against Bordetella and still develop respiratory illness caused by another organism.
Even when Bordetella is involved, vaccination does not necessarily prevent every infection.
The goal of vaccination is to reduce the risk and, in many cases, lessen the severity of disease rather than promise complete protection.
What Does Kennel Cough Sound Like?
One of the classic signs is a sudden, dry, harsh cough.
Owners sometimes describe it as sounding like:
- Honking
- Gagging
- Something stuck in the throat
- Repeated throat clearing
Some dogs may also have nasal discharge, reduced appetite, tiredness, or other respiratory symptoms.
Many mild respiratory infections improve with supportive care, but coughing should not automatically be assumed to be kennel cough.
Heart disease, pneumonia, airway problems, and other conditions can also cause coughing.
When Should You Call a Veterinarian?
Contact your veterinarian if your dog develops a persistent cough, especially after spending time around other dogs.
More urgent veterinary attention may be appropriate if your dog also has:
- Difficulty breathing
- Significant lethargy
- Fever
- Loss of appetite
- Thick or pus-like nasal discharge
- A wet or productive cough
- Symptoms that are getting worse instead of better
More serious respiratory disease can occur, particularly in puppies or dogs with underlying health problems.
If your dog is coughing, it is also a good idea to avoid daycare, boarding, dog parks, and other close contact with dogs until your veterinarian advises that it is safe.
Is the Bordetella Vaccine Safe?
Vaccines can cause side effects, but serious reactions are uncommon.
Depending on the vaccine type, some dogs may experience temporary symptoms such as mild sneezing, coughing, or nasal discharge after an intranasal vaccine. Older WSAVA guidance notes that these mild respiratory signs can occasionally occur for several days following vaccination.
Other mild vaccine reactions can include temporary tiredness or soreness.
If your dog has had a previous vaccine reaction, has an underlying illness, or takes medication that affects the immune system, discuss this with your veterinarian before vaccination.
Any facial swelling, collapse, breathing difficulty, or other severe reaction after vaccination should be treated as an emergency.
Bordetella vs. Canine Influenza Vaccine
These are not the same vaccine.
Bordetella vaccines target Bordetella bronchiseptica.
Canine influenza vaccines protect against particular strains of canine influenza virus.
Because both can contribute to respiratory disease outbreaks, a veterinarian may recommend both for some highly social dogs. AAHA lists Bordetella and canine influenza among lifestyle-based vaccines that may be important depending on a dog’s risk.
One vaccine does not automatically replace the other.
Does My Indoor Dog Need a Bordetella Vaccine?
Possibly not — but “indoor dog” does not always mean “low risk.”
Think about where your dog actually goes.
An apartment dog who attends daycare five days a week may have far more exposure to respiratory disease than a dog who spends most of the day outside on a private rural property.
Risk is mostly about contact with other dogs, not simply whether your dog sleeps indoors.
If your dog does not regularly spend time around unfamiliar dogs, your veterinarian may decide Bordetella vaccination is unnecessary.
What About Puppies?
Puppies can receive Bordetella vaccines, but the minimum age and initial schedule depend on the specific product.
AAHA vaccination guidance distinguishes between intranasal, oral, and injectable formulations, so there is not one universal puppy Bordetella schedule that applies to every vaccine.
This is one reason it is better to ask your veterinarian which product your puppy received rather than simply asking, “Did my puppy get the kennel cough shot?”
If your puppy will attend puppy classes, daycare, grooming, or boarding, tell your veterinarian so they can build those exposure risks into the vaccination plan.
Angel Jake’s Take
The Bordetella vaccine is a good example of why dog vaccination is not always a simple checklist.
Two healthy dogs of the same age can have completely different needs.
One may spend almost every day at daycare, while another may rarely come into close contact with unfamiliar dogs.
For us, the important thing is not giving every vaccine simply because it exists. It is understanding why your individual dog may need it.
If your dog regularly shares space, water bowls, play areas, or indoor air with other dogs, Bordetella is worth discussing with your veterinarian.
And if you use daycare or boarding, check their vaccine rules before you actually need the reservation. Finding out your dog’s vaccine does not meet a facility’s requirement the night before a trip is something most dog owners would rather avoid.
Frequently Asked Questions
How often do dogs need the Bordetella vaccine?
For dogs considered at risk, AAHA guidance generally recommends annual revaccination. The exact schedule can depend on the vaccine product, your dog’s exposure risk, and facility requirements.
Does every dog need a Bordetella vaccine?
No. Bordetella is considered a lifestyle- or risk-based vaccine for household dogs. Dogs that regularly spend time around other dogs are more likely to benefit from it.
Can my dog still get kennel cough after the vaccine?
Yes. Kennel cough can involve several different bacteria and viruses, and the Bordetella vaccine only targets part of that risk.
Does Bordetella protect against canine flu?
No. Bordetella and canine influenza are different infections and use different vaccines.
Is Bordetella required for dog daycare?
Many facilities require it, but policies vary. Always check the individual daycare or boarding facility before your dog’s visit.
Is Bordetella the same as the kennel cough vaccine?
People commonly use those terms interchangeably, but “kennel cough” can involve several different respiratory pathogens. Bordetella bronchiseptica is only one of them.
