Kennel cough, also known as canine infectious tracheobronchitis, is a contagious respiratory disease in dogs that causes a harsh, dry cough. This condition can spread quickly in places where many dogs are in close contact, such as kennels, dog parks, and grooming salons. To protect dogs from kennel cough, many veterinarians recommend the kennel cough injection or vaccine, which helps prevent the disease.
While the kennel cough injection is generally considered safe, like any vaccine, it may cause side effects in some dogs. It is important for dog owners to be aware of these potential side effects so they can respond appropriately if their pet experiences any issues.

What is the Kennel Cough Vaccine?
The kennel cough vaccine is designed to protect dogs from the main bacteria and viruses that cause kennel cough. These include Bordetella bronchiseptica, a bacterium, and sometimes the canine parainfluenza virus. The vaccine works by introducing a small amount of these pathogens into the dog’s system, which helps the immune system recognize and fight the infection in the future.
The kennel cough vaccine can be administered in a few different ways: as an injection, an oral dose, or a nasal spray. The injection form is the most commonly used in veterinary clinics.
Common Side Effects of the Kennel Cough Injection
While most dogs handle the kennel cough vaccine without any problems, some may experience mild side effects. These side effects are usually temporary and go away on their own. Below are the most common side effects that can occur after a dog receives the kennel cough injection.
1. Mild Lethargy
One of the most common side effects is mild lethargy. After the injection, some dogs may appear tired or less active than usual. This is a normal response as the dog’s immune system works to adjust to the vaccine. In most cases, this tiredness should subside within a day or two.
2. Soreness or Swelling at the Injection Site
Just like any other injection, the kennel cough vaccine may cause soreness or swelling at the site where the needle was inserted. This may cause the dog to be sensitive to touch in that area. In some cases, a small lump may form at the injection site. This lump usually disappears within a few days.
3. Mild Fever
A mild fever is another common side effect after the kennel cough injection. The fever typically indicates that the immune system is reacting to the vaccine and building protection against the disease. If the fever is low-grade (usually under 103°F or 39.4°C) and lasts only for a short time, it is not usually a cause for concern.
4. Reduced Appetite
Some dogs may lose their appetite for a short time after receiving the kennel cough vaccine. This is often due to the mild discomfort or fatigue that can follow the injection. As long as the dog continues to drink water and the loss of appetite doesn’t last more than a day or two, there is no need to worry.
5. Coughing or Sneezing
It’s possible that a dog may experience mild coughing or sneezing after receiving the kennel cough vaccine, especially if the vaccine was given via the nasal spray method. However, these symptoms are usually mild and should resolve within a short period.
Less Common but Serious Side Effects
Although rare, some dogs may experience more serious side effects after receiving the kennel cough injection. These serious reactions require prompt veterinary attention. If you notice any of the following symptoms, it’s important to contact your veterinarian right away.
1. Allergic Reactions
Some dogs may have an allergic reaction to the vaccine. Symptoms of an allergic reaction can include swelling of the face, ears, or paws, hives, difficulty breathing, vomiting, or diarrhea. If you notice any of these signs, it is important to seek immediate veterinary care.
2. Vomiting or Diarrhea
While mild gastrointestinal upset can occur after vaccination, severe vomiting or diarrhea is not common. If your dog experiences persistent vomiting or diarrhea after the vaccine, it could be a sign of an adverse reaction, and you should consult your vet.
3. Difficulty Breathing
In very rare cases, a dog may develop difficulty breathing after receiving the kennel cough vaccine. This is usually a sign of an allergic reaction and requires urgent veterinary care. If your dog has trouble breathing or appears to be in distress, seek immediate medical help.
4. Collapse or Fainting
Although extremely rare, some dogs may experience a sudden collapse or fainting episode after vaccination. This could indicate a severe reaction and should be treated as an emergency. If your dog collapses or faints, call your veterinarian immediately.
Preventing Side Effects
While most side effects of the kennel cough injection are mild and temporary, there are a few steps you can take to minimize the risk of adverse reactions:
- Consult Your Vet: Before vaccinating your dog, have a conversation with your veterinarian about any known allergies or health conditions your dog may have. Your vet will help determine the best course of action.
- Monitor Your Dog After the Injection: It’s a good idea to keep an eye on your dog for the first 24-48 hours after the vaccine. If you notice any unusual behavior or symptoms, contact your vet right away.
- Stay Up-to-Date on Vaccinations: Make sure your dog receives all necessary vaccinations according to the veterinarian’s recommendations. A well-timed vaccination schedule helps to keep your dog’s immune system strong and better able to handle the vaccine.
When to Seek Veterinary Help
If you notice any of the following symptoms after your dog receives the kennel cough injection, contact your vet immediately:
- Persistent vomiting or diarrhea
- Swelling of the face, lips, or tongue
- Difficulty breathing or labored breathing
- Collapse or fainting
- Lethargy lasting more than a few days
- Severe coughing or coughing that gets worse
It is always better to err on the side of caution if you are unsure whether your dog’s symptoms are normal or something more serious.
Conclusion
The kennel cough injection is an important tool in protecting dogs from the highly contagious disease known as kennel cough. While the vaccine is generally safe and well-tolerated, there can be mild side effects such as soreness, fatigue, mild fever, and reduced appetite. Serious side effects, though rare, can occur and may require immediate veterinary attention.
As a responsible pet owner, it’s important to stay informed about the possible side effects of any vaccination and to monitor your dog after they receive the kennel cough vaccine. By working closely with your veterinarian, you can ensure that your dog stays healthy and protected from contagious diseases like kennel cough.
