The benefits of vaccinating your dog nearly always outweigh any risk of reactions they might have to those vaccines. For dog illnesses like Bordetella—or Kennel Cough—there are some possible reactions your dog may have to their appropriate vaccinations. Here, our Ocala vets provide some guidance on the common reactions to the Bordetella vaccine in dogs as well as what to do if your dog has a serious reaction.
Why should I get my dog vaccinated against Bordetella?
Kennel cough, also known as Bordetella, is a commonly transmitted upper respiratory infection. Furthermore, if you take your dog to a daycare, boarding house, or group obedience class, someone will almost certainly ask, "Is your dog vaccinated against kennel cough?" Bordetella, parvovirus, rabies, hepatitis, and other infections in dogs can cause severe symptoms or death. Vaccinations, such as the Bordetella shot, protect your dog's health by preventing these illnesses from occurring in the first place.
How long does a Bordetella vaccine last in dogs?
If you're wondering how often a dog needs a Bordetella shot, it is usually every 6 months to a year.
Both an injection and an intranasal spray are available for this pet vaccination, which your veterinarian will administer to your dog's nose. Both are equally efficient. While the nasal spray version of the Bordetella vaccine can be given to dogs as young as 6 weeks old, the injectable version is only suitable for dogs older than 8 weeks.
What are the most common side effects of the Bordetella vaccine in dogs?
Mild negative side effects from Bordetella vaccinations are not only possible but also typical in dogs. Although it may be upsetting to see your pet react to vaccination, it's important to remember that most of these reactions are mild and relatively transient. It can be less stressful for both you and your dog to receive a Bordetella vaccination if you know what to look out for in terms of vaccine reactions and what to do if your pup starts exhibiting more severe symptoms.
Lethargy
The most common side effect of the Bordetella vaccine for dogs is a feeling of malaise, lethargy, or discomfort, which is often accompanied by a low fever. This sensation is commonly referred to as "off." This reaction indicates that your dog's immune system is properly responding to the vaccine. These symptoms should only last a day or two and are completely normal. After a few days, if your dog's energy level has not returned to normal, contact your veterinarian.
Lumps & Bumps
If your dog receives the injectable form of the Bordetella vaccine, lumps and bumps can occur, especially around the injection site. A small, firm bump may develop, as well as some tenderness and stiffness in the area. These bumps are the result of your dog's immune system rushing in to fight irritation at the injection site.
However, piercing the skin increases the risk of infection. Carefully monitor the area where the injection was administered. Keep an eye out for symptoms like pain, redness, discharge, and swelling. If infected areas are not treated, they may develop into more severe conditions. Contact your veterinarian if you notice the area becoming redder or exhibiting any of the symptoms listed above.
Sneezing & Cold-Like Symptoms
If your dog received the Bordetella vaccine as a nasal spray, this reaction may occur frequently. After the Bordetella vaccine, your dog may exhibit a number of symptoms that resemble a cold, such as coughing, sneezing, and runny nose. Most dogs get better in a day or two from these symptoms. It's time to call the vet if your dog exhibits more severe symptoms or does not get better within a few days.
Serious Reactions to Vaccinations
Most of the reactions associated with vaccinations are both mild and quite short-term. In some rare cases, more severe reactions may occur, however, and will require immediate medical attention.
Anaphylaxis is the most frequent of these incredibly uncommon reactions. This is a severe allergic reaction that can manifest in your dog as facial swelling, hives, vomiting, breathing difficulties, diarrhea, and itching. This reaction usually appears shortly after your dog receives a vaccination, but it could take up to 48 hours to manifest. After receiving the Bordetella vaccine, if your dog displays any anaphylaxis symptoms, call your emergency veterinarian right away.
Can I prevent my dog from having a reaction to the Bordetella vaccine?
Vaccines help to protect your pup's long-term health and well-being, preventing diseases from ever arising in the first place. And the risk of your canine companion having a serious adverse reaction to vaccination is quite low.
All of that being said, if your dog has previously had a reaction to a vaccine, be that for Bordetella or a different disease, always inform your vet ahead of time. They may advise you to skip a certain vaccine in the future to mitigate risks—especially for an optional vaccine like Bordetella.
When multiple vaccinations are given at the same time, the risk of adverse reactions increases slightly. Smaller dogs may be particularly vulnerable to this. To reduce the risk of reactions, your veterinarian may advise you to administer your dog's Bordetella vaccine separately from any other required vaccinations over several days.
