Dog Vaccinations Side Effects

Most pet owners take their dogs to the veterinarian for vaccination and get an annual checkup. Although some dogs leave the office and do not have problems or problems with vaccines, some dogs receive an injection and suffer from a variety of side effects. Typical dog vaccines include rabies, adenoviruses, nuisance, hepatitis, retroviruses, areola, and Para influenza.

Side effects and risks associated with dog vaccinations
The benefits of vaccines outweigh any risks. Negative reactions to dog vaccines are rare. However, as with any medication or immunization protocol, dog vaccinations and dog vaccinations can cause some side effects. We recommend vaccinating your puppy or dog while you can monitor it after vaccination.

If your dog has any reaction to vaccinations, symptoms may include:

  • Vomiting
  • Diarrhea
  • Fever
  • Slowdown
  • Anorexia
  • Swelling and/or urticaria in the face or feet
  • Pain or swelling around the injection site
  • Collapse, difficulty breathing, seizures (anaphylactic shock)
  • As with human vaccines, mild symptoms can be ignored. The majority of reactions are mild and short-lived. If you suspect a more severe reaction to puppy vaccines or dog vaccines, such as swelling of the face, vomiting, or lethargy, you should contact your vet immediately.

Just as humans sometimes have a vaccination-related fever, dogs can also. It may be just a low-grade fever that lasts for a day or so after vaccination or even just a few hours. Talk to your veterinarian if this happens more than once and it may be advised to give your dog a moderate fever dilution to prevent or treat fever in the future.

Pain and tenderness
It is normal to feel pain at the injection site. It may also form a small lump that should dissipate over the next few days to a week. The dog may feel tenderness around the injection area, so refrain from touching it in this place until the pain subsides. You may talk to your vet about using a different injection area next time to see if this side effect can be avoided or reduced.

Breathing difficulty
Some dogs may interact seriously with vaccination and side effects can be life-threatening. If you notice any swelling around the dog’s face when leaving the vet office, be sure to seek immediate care. She may have an allergic reaction and is likely to be given epinephrine, which will reverse the reaction that occurred from the vaccination. This special vaccination should be avoided and not used again on the dog.

Dizzy and confused
Dogs can get dizzy and confused after vaccination. The dog may not be the same, maybe he walks into things, steps aside and may fall. This side effect usually occurs minutes after administration of the vaccine and can be monitored by a veterinarian. Make sure to closely monitor the dog, help it rise and fall stairs if necessary, and reassure the dog that you are there. Your dog may become anxious about his mysterious mental state, so some extra love may be a good idea for your pet.

Perhaps the most common side effect of dog vaccinations is that the dog has become idle after visiting it. It is normal for the dog to tire after this and the injection may sleep for the rest of the afternoon. They may even appear lazy and are less active the next day or after the administration of the injection. Although inactivity is normal, it should not exceed more than one day after reaching home. Call the office to alert the vet if there is a need for concern.

How long do the dog vaccine side effects last?
Most reactions occur within 48 hours of vaccinating a dog, but some take longer. If your dog suffers from a mild reaction, it will generally last for a short period, only a few days. However, there is much debate in the veterinary community about other side effects that can develop later in your dog’s life.
