Dog Behavior Change After Vaccination

Ensure the health of your canine companion by administering essential vaccinations. Without these crucial vaccines, your dog may risk developing various serious diseases. At Rivergate Veterinary Clinic our vets emphasize the significance of dog vaccinations, discuss anticipated behavioral changes post-vaccination, and explain why your puppy might exhibit unusual behavior after receiving their shots.

Why are vaccines essential to your dog's health?

As a responsible pet owner, you recognize the significance of vaccinations in safeguarding your furry friend from various serious and highly contagious diseases.

Your dog's health relies on vaccinations, protecting against numerous severe and potentially fatal diseases and conditions. Despite some pet owners expressing concerns about the safety of these vaccinations, extensive research and testing ensure their maximum safety. The potential risks associated with these devastating illnesses far outweigh any concerns related to vaccinations.

Nevertheless, it's worth noting that dogs commonly undergo certain behavioral changes after receiving vaccinations. The following are some potential reasons for these changes and their underlying factors.

What to Expect After Your Dog's Vaccinations

Expect changes in your dog's behavior after rabies vaccination or other critical vaccines. Although these changes might appear alarming, remember that they are generally temporary and vary from dog to dog. Your puppy may even become hyper after vaccinations. Here are some other responses you may observe after your dog's vaccinations:

  • Lethargy - Some dogs may experience lethargy or fatigue after vaccinations. This is a natural response as the body diverts energy to build an immune response. Allowing your dog time to rest and recover is crucial during this period.
  • Decreased Appetite - Vaccinations can temporarily affect a dog's appetite. If your pet seems less interested in eating immediately after receiving shots, it is often nothing to be overly concerned about. Ensure they have access to fresh water and monitor their eating habits. If the reduced appetite persists for over a day or two, consult your veterinarian.
  • Mild Discomfort - In some cases, dogs may experience mild discomfort or soreness at the injection site. They might exhibit signs of sensitivity when touched or avoid weighting the affected leg, especially if the vaccine was administered in the leg region. This discomfort usually subsides within a few days.

Why Do Behavior Changes Happen

So why is your dog acting weird after their rabies shot or other vaccinations? Various factors can contribute to the behavioral changes you might observe in your dog following their vaccinations. It is essential to consider these factors when evaluating your dog's response to the vaccines they recently received:

  • Individual Sensitivity - Dogs have sensitivities and reactions to vaccines that are different from humans. Some dogs may be more susceptible to experiencing behavioral changes, while others may show no noticeable difference.
  • Vaccine Components - Vaccines contain specific components, such as adjuvants or preservatives, to enhance their effectiveness and shelf life. In rare cases, dogs may exhibit allergic reactions to these components, leading to more pronounced behavioral changes. Discuss any concerns with your veterinarian to ensure the right vaccines are administered.
  • Stress and Anxiety - Veterinary visits, including vaccinations, can induce stress and anxiety in dogs. The anticipation of discomfort, strange environments, or unfamiliar people can trigger temporary changes in behavior. Comforting your dog with gentle reassurance and positive reinforcement can help alleviate stress during these visits.

When You Should Seek Veterinary Care

While most behavioral changes after vaccinations are normal and resolve within a few days, some situations may require veterinary attention. Contact your veterinarian if you notice any of the following:

  • Severe or Prolonged Behavior Changes - If your dog's behavior changes are severe, persist for an extended period, or worsen over time, consult your veterinarian. These changes could indicate an adverse reaction or an unrelated underlying issue.
  • Allergic Reactions - If your dog exhibits signs of an allergic reaction, such as excessive swelling, difficulty breathing, or vomiting, seek immediate veterinary care. Allergic reactions are rare but can be serious.
  • Uncharacteristic Behavior - If your dog displays unusual behavior unrelated to the common changes mentioned earlier, it is advisable to consult a veterinarian. They can help determine if the behavior is vaccine-related or stems from another health concern. 

Should you have your dog vaccinated?

Behavioral changes in dogs after vaccinations commonly occur and are usually harmless. To ensure a positive and healthy experience for your furry companion, understand the purpose of vaccinations, be aware of potential behavior changes, and monitor your dog's well-being.

If you have concerns about the safety of dog vaccinations, consult with your vet to determine whether your dog should be vaccinated. Your vet can assess your pup's overall health, lifestyle, and risk factors to assist you in deciding whether vaccinations are appropriate for your dog.
