Your Guide to Dog Behavior Changes After Vaccinations

It's important to know that it is quite common for pets to exhibit changes in behavior following vaccinations. If your pet is about to go for their shots, it's important to be aware of this. Our veterinarians in Gilbert have explored the topic of dog behavior change after vaccinations, common concerns, and possible reasons behind these changes.

Vaccinations & Your Dog's Health

As a responsible pet owner, you likely understand the significance of vaccinations in safeguarding your furry friend from various serious and highly contagious diseases. Vaccinations play a vital role in your pet's yearly preventive healthcare plan, protecting your dog's well-being from potentially life-threatening illnesses.

While concerns have been raised over the years regarding the safety of vaccines, our team of skilled veterinarians firmly believes that the benefits of vaccines outweigh the risks when it comes to protecting the long-term health of most dogs. However, it's essential to note that changes in behavior are not uncommon following vaccinations. Below are some of the possible reasons for behavior changes in dogs after vaccines and why they may occur.

Common Behavior Changes After Vaccinations

A change in your dog's behavior after rabies vaccination or other critical vaccines can be expected. While these changes may seem alarming, it is important to remember that they are generally temporary and vary from dog to dog. You may even have a puppy that becomes hyper after vaccinations. Here are some of the other responses that you may see 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 -After receiving vaccinations, dogs may experience a temporary loss of appetite. However, this is usually not a cause for alarm. You should make sure that your pet has access to clean water and keep an eye on their eating habits. If your dog's appetite does not improve within a day or two, it is recommended that you consult with your veterinarian.
  • Mild Discomfort - Sometimes, dogs may feel a little uncomfortable or soreness at the spot where they received a vaccine injection. They might show signs of sensitivity when touched, or avoid putting weight on the leg where the vaccine was given. This is more common if the vaccine was administered in the leg region. However, this discomfort usually goes away within a few days.

Factors Influencing Behavioral Changes

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 - 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.
  • Vaccine Components - Vaccines are composed of various components, such as adjuvants and preservatives, that increase their potency and shelf life. However, in rare cases, some dogs may develop allergic reactions to these components, which can cause significant changes in their behavior. If you have any concerns about your dog's reaction to vaccines, it is best to discuss them with your veterinarian. This will ensure that only the appropriate vaccines are administered to your dog.
  • Stress and Anxiety - Dogs can experience stress and anxiety during veterinary visits, especially during vaccinations. This can be caused by the anticipation of discomfort, unfamiliar surroundings, or unknown people, resulting in temporary changes in behavior. To help alleviate your dog's stress, it's essential to provide gentle reassurance and positive reinforcement during these visits.

When to Seek Veterinary Advice

After vaccinations, most behavioral changes are normal and resolve within a few days. However, if you notice any of the following symptoms, it may require veterinary attention. Contact your veterinarian immediately.

  • 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. 

Are Vaccines Right For Your Dog?

It is relatively common for dogs to experience behavioral changes following vaccinations, which are typically harmless. To ensure a positive and healthy experience for your furry companion, it is important to 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, it is best to speak to your vet. They can assess your pup's overall health, lifestyle, and risk factors to help you decide whether vaccinations are right for your dog.
