Side Effects of the Bordetella Vaccine in Dogs — and How to Help Them Recover Naturally

Being loving dog parents, it can be hard seeing our furry kids down in the dumps after a vaccine. The Bordetella shot is an important part of preventing kennel cough, which means that once the worst has passed and it’s time for rest and recovery, you need to know how to help your sick dog as well.

This ultimate guide outlines the side effects of Bordetella vaccine in dogs and provides natural, supportive care tips that will allow your dog to recover comfortably and quickly.

What Is the Bordetella Vaccine and Why Do Dogs Need It?

The Bordetella vaccine shields dogs from exposure to Bordetella bronchiseptica — the bacteria that causes what we commonly call kennel cough, an infectious respiratory disease. It can travel quickly in facilities with a lot of doggy traffic, including dog parks, boarding kennels and grooming parlors.

This vaccine comes recommended by veterinarians for dogs who regularly come in contact with other pets, as it lessens the severity of any illnesses and stops large outbreaks.

The vaccine comes in three different parts:

• Nasal (Intranasal): A spray given into your dog’s nose.
• Oral: Drops administered into the mouth.
• Injection: A traditional shot given under the skin.
  
  

Each version offers strong protection, though mild, temporary reactions are normal as the body builds immunity.

Common Side Effects of the Bordetella Vaccine in Dogs

Most of the side effects are signalling that the immune system is responding properly in your dog. They are mostly mild and transient and usually resolve spontaneously

Common side effects include:

• Slight fever or tiredness (lethargy)
• Sneezing or light coughing (mainly for nasal and oral vaccines)
• Watery eyes or nasal discharge
• One to two days of reduced appetite
• Some redness or swelling or soreness at the injection site

These typically develop within 24–48 hours and resolve on their own.

Make sure your dog is hydrated and has had plenty of rest and do not play to the point of exhaustion until they are back up to full energy.

When to See a Vet: Signs of an Allergic Reaction

Although rare, some dogs may experience serious allergic reactions that need immediate veterinary attention.
Contact your vet right away if your dog shows:

• Facial swelling (around eyes, muzzle, or throat)
• Persistent vomiting or severe diarrhea
• Continuous, harsh coughing or wheezing
• Difficulty breathing or sudden weakness
• Fainting or collapse

How Long Do Side Effects Last?

Now, many dog owners have this question, how long after Bordetella vaccine does my dog get side effects (oral Bordetella vaccine side effects timeline).

• Systemic Side Effects (Fatigue/Fever): More prominent in 12–24 hours and last up to two days.
• Respiratory Side Effects (Cough/Sneeze): Nasal or oral forms may take the week to 5 to 7 days to stay around. This is okay because it is the building of local defense during which the immune system creates the local response.

Contact your vet for assessment if symptoms last more than seven days or become severe.
