Bordetella Vaccine: Understanding Post-Vaccination Tiredness in Dogs
Bordetella Vaccine & Tiredness
Yes, the Bordetella vaccine can make a dog tired. Lethargy is a common, mild side effect that many pet owners observe after their dog receives this vaccination. This reaction is a normal part of the immune response.
This tiredness is usually temporary, typically lasting for 1-2 days. During this period, your dog's immune system is actively working to build protection against the Bordetella bacteria.
Why Dogs Need the Bordetella Vaccine
The Bordetella vaccine is crucial for protecting dogs against kennel cough. Specifically, it targets Bordetella bronchiseptica, which is a primary bacterial agent responsible for infectious tracheobronchitis, commonly known as kennel cough (Source 3).
Kennel cough is a highly contagious respiratory disease. It spreads easily among dogs, especially in environments where multiple dogs congregate and interact (Source 2, Source 3).
The vaccine is highly recommended for social dogs due to the contagious nature of kennel cough. Dogs that frequently visit certain facilities or interact with other canines benefit greatly from this protection (Source 1, Source 3, Source 5).
These facilities include:
- Boarding kennels
- Doggy daycares
- Dog parks
- Grooming salons
- Training classes
- Dog shows
How the Vaccine Works & Expected Reactions
The Bordetella vaccine functions by introducing a small amount of the bacteria into your dog's system. This can be in an inactivated or weakened form, depending on the vaccine type (Source 1).
This exposure stimulates the dog's immune system. It prompts the body to produce protective antibodies, preparing it to fight off actual Bordetella infection if exposed in the future.
Common mild side effects are generally observed for 1-2 days post-vaccination. These indicate that the immune system is responding as expected (Source 1, Source 5).
Mild side effects include:
- Lethargy or tiredness
- Mild fever
- Decreased appetite
- Sneezing, a mild cough, or a runny nose (more common with the intranasal vaccine)
- Slight swelling or tenderness at the injection site (for injectable vaccines)
Post-Vaccination Care Checklist
After your dog receives the Bordetella vaccine, it's important to monitor them closely. Observe your dog for any unusual symptoms for at least 24-48 hours (Source 1).
Provide a quiet and comfortable environment for your dog to rest. This allows their body to recover and build immunity without added stress.
Ensure your dog has constant access to fresh water. Staying hydrated is important for their overall well-being, especially when their immune system is active.
If your dog's appetite is reduced, offer smaller, easily digestible meals. This can help prevent an upset stomach while still providing necessary nutrition.
Avoid strenuous activity immediately after vaccination. Postpone vigorous exercise, long walks, or stressful situations to allow your dog to conserve energy and recover.
Tools & Products for Comfort
To enhance your dog's comfort during their recovery period, consider providing a soft and comfortable bed. A familiar, cozy sleeping spot can help them feel secure and rest better.
Always ensure they have easy access to fresh water. A clean water bowl kept nearby encourages hydration.
Offer their favorite toys for gentle distraction. This can provide comfort without requiring much physical exertion.
In some cases, your veterinarian might recommend a mild, vet-approved pain reliever. This is typically for injection site soreness, but always consult your vet before administering any medication.
Risks & When to See a Vet
Mild lethargy and a low-grade fever are common and generally normal reactions to the Bordetella vaccine. These symptoms usually resolve on their own within a day or two (Source 1, Source 5).
However, some signs indicate a more serious reaction that requires immediate veterinary attention (Source 5).
Seek vet care immediately if you observe any of the following:
- Severe vomiting or diarrhea
- Facial swelling or hives
- Difficulty breathing
- Collapse or extreme weakness
- Persistent high fever (above 103°F / 39.4°C)
- Symptoms lasting longer than 48 hours
Bordetella Vaccine FAQ
❓ Frequently Asked Questions
Does the vaccine guarantee no kennel cough?
No, the Bordetella vaccine significantly reduces the risk and severity of kennel cough caused by *Bordetella bronchiseptica*. However, other viruses and bacteria can also cause kennel cough, so vaccination does not offer 100% protection against all forms of the illness (Source 2, Source 3).
How is the vaccine given?
The Bordetella vaccine can be administered in a few ways: as an injectable shot, as intranasal drops (given into the nose), or as an oral liquid (Source 5). Your veterinarian will determine the best method for your dog.
How often is it needed?
The Bordetella vaccine is typically recommended annually for most dogs, especially those at higher risk of exposure. Puppies often require an initial series of vaccinations. The exact frequency can vary based on your dog's lifestyle and your veterinarian's recommendation (Source 2).
Is it a "core" vaccine?
No, the Bordetella vaccine is considered a "non-core" vaccine. This means it is recommended based on a dog's individual lifestyle, risk of exposure, and geographic location, rather than being universally recommended for all dogs (Source 2, Source 3, Source 5).
Can my dog get kennel cough from the vaccine?
With the intranasal Bordetella vaccine, some dogs may develop mild, temporary kennel cough-like symptoms, such as sneezing or a slight cough. This is a normal immune response to the weakened virus in the vaccine and is not a full-blown infection (Source 1). The Bordetella vaccine is an important tool for protecting dogs, especially those who frequently socialize, from kennel cough. While it's common for dogs to experience mild, temporary tiredness and other minor side effects for a day or two as their immune system responds, these reactions are generally normal and indicate the vaccine is working. Pet owners should monitor their dogs closely post-vaccination and contact their veterinarian immediately if any severe or prolonged symptoms occur.
