My Dog Reacts to a Vaccine – What Should I Do?

Since vaccination is often advised annually, most pet owners are used to bringing their pets to the veterinarian for “annual vaccinations.” Countless owners need to give their pets’ inner health more thought since it appears like a normal part of regular pet care. Because immunization causes the body’s immune system, it always causes inflammation.

What are the symptoms of vaccine reactions in dogs?

It can be challenging to witness an adverse reaction to a dog’s vaccinations. Nevertheless, responsible pet owners should be aware that several reactions are minor, momentary, and typically much less damaging than the ailments the vaccinations intend to avoid.

Learning the most frequent vaccine reactions in dogs and what to do if your pet experiences a reaction will make immunization time less bothersome for you and your pet.


Vaccines usually trigger lethargy, minor pain, and low-grade fever in dogs. Symptoms include a change in your dog’s actions, such as a lack of energy. These reactions following vaccination are common in dogs and typically subside after a day or more. If your dog’s reaction lasts more significant than a few days, it’s time to call the veterinarian.

Nevertheless, if the shot site is inflamed, a veterinarian from an animal hospital like Ellenton Animal Hospital might recommend cold laser therapy to relieve swelling and discomfort.

Cold Like Symptoms & Sneezing

Nevertheless, the Bordetella bronchiseptica and parainfluenza virus vaccinations are provided as drops or sprays in the dog’s nose rather than injections. Intranasal vaccination reactions can simulate the common cold, with signs like a stuffy nose, coughing, and sneezing.

Your dog should feel better in a day or more at the very most after experiencing these symptoms. If your dog’s symptoms linger or aggravate after a few days, it’s time to visit with the veterinarian.

What to do during the vaccine reaction?

If your pet has a reaction beyond mild exhaustion or discomfort, you should call your veterinarian instantly. It’s best to go to the nearest emergency clinic if it’s after regular business hours. Shots of anti-inflammatory drugs can prevent the inflammatory reaction before it creates severe damage. After vaccinating your pet, familiarize yourself with the emergency contact information.

Vomiting may indicate a strong response or car sickness. The vet needs to be informed if vomiting is seen. If your dog has an adverse reaction to a vaccine, having the number of a trusted vet who provides pet vaccinations is essential.

How can vaccine reactions in dogs be avoided?

Antihistamines and corticosteroids given before immunizing a dog with an allergy history can lessen the severity of the reaction. These medications may be provided intravenously at the beginning of the vaccination session or orally 1– 2 hours before the shot.

More vaccines given at once increase the risk of an adverse reaction. Your veterinarian might advise giving your high-risk dog vaccinations two weeks apart. In addition, a pet wellness plan and regular exams for your dog are other vital safety measures to take. If you want to learn more about pet wellness plans, it is best to visit the vet’s website.

The Takeaway

Vaccine-related responses in dogs are relatively uncommon but could be of varying severity. Consult your veterinarian concerning future vaccines for your dog if they have experienced a vaccine reaction. Your dog’s health and safety need to be your top priorities while determining whether or not to vaccinate it. Get your dog the best care possible by teaming up with a trustworthy vet.
