My Pet Is Itchy After Vaccination

Before taking your pet for their vaccinations, it's crucial to recognize that observing certain changes in their behavior afterward is typical. Here, our Fort Worth vets explore the topic of dog behavior change after vaccinations, possible reasons behind these changes, and common concerns.

Vaccinations & Your Dog's Health

As a responsible pet owner, you understand the importance of vaccinations when it comes to protecting your furry friend from a range of serious and highly contagious diseases.

Vaccinations play a vital role in your pet's yearly preventive healthcare regimen, shielding your dog from potentially fatal diseases. Despite occasional safety concerns raised over the years, our team of seasoned veterinarians staunchly asserts that the advantages of vaccines in safeguarding the overall well-being of most dogs far surpass any associated risks.

Nonetheless, it's important to note that it is not uncommon to notice changes in their behavior following vaccinations. Below are a few of the possible reasons for behavior changes in dogs after vaccines and why they may occur.

Common Behavior Changes After Vaccinations

It is not uncommon for dogs to display behavioral changes after receiving their shots. These are more than just your dog's vaccine side effects. While these changes may seem alarming, it is important to remember that they are generally temporary and vary from dog to dog. Here are a few common behavior changes pet owners may observe:

  • Mild Discomfort -Occasionally, dogs may encounter slight discomfort or tenderness at the site of the injection. They might display sensitivity when touched or avoid putting weight on the affected leg, particularly if the vaccine was given in that area. However, this discomfort typically diminishes within a few days.
  • 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 more than a day or two, consult your veterinarian.

Puppy Itching After Vaccination

If your dog is itchy after vaccines, keep in mind that it is normal. Allergens like pollen, which previously posed no problem for your dog pre-vaccine, might now trigger seasonal discomfort. This can manifest as intense itching, redness, and uncontrollable inflammation.

What was once a healthy and happy pup could now be relentlessly chewing and scratching her fur, incessantly licking herself raw throughout the night, or even gnawing at her skin until it bleeds, all because of this relentless, overpowering itch. 

Factors Influencing Behavioral Changes

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 - Just like humans, dogs have different sensitivities and reactions to vaccines. Some dogs may be more susceptible to experiencing behavioral changes, while others may show no noticeable difference.
  • 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.
  • Vaccine Components - Vaccines are formulated with specific elements like adjuvants or preservatives to bolster their efficacy and durability. While uncommon, some dogs may display allergic reactions to these components, resulting in noticeable shifts in behavior. It's important to address any concerns with your veterinarian to ensure the appropriate vaccines are administered.

When to Seek Veterinary Advice

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 experiences significant behavioral shifts that endure for an extended duration or deteriorate over time, it's advisable to seek advice from your veterinarian. These alterations could signal an adverse reaction to something or an unrelated underlying issue.
  • Allergic Reactions - If your dog exhibits signs of an allergic reaction to a vaccine, 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. 

Are Vaccines Right For Your Dog?

It's quite common for dogs to exhibit behavioral changes after vaccinations, usually without harm. Familiarizing yourself with the purpose of vaccinations, staying mindful of potential behavior alterations, and keeping an eye on your dog's overall well-being will contribute to a positive and healthy experience for your beloved pet.

If you are concerned about the safety of dog vaccinations speak to your vet to determine whether your dog should your dog should be vaccinated. Your vet can assess your pup's overall health, lifestyle, and risk factors to help you decide whether vaccinations are right for your dog.
