Do Puppy Vaccine Make Them Tired? Truth about Dog Vaccinations

Puppies, with their boundless energy and playful antics, can sometimes exhibit signs of tiredness after receiving vaccinations. As a responsible pet owner, it's natural to wonder if these vaccines are the culprit behind your furry friend's momentary lethargy. Let's delve into the world of puppy vaccines and explore the common reactions they may induce.

What Are Dog Vaccines And Why Are They Important?

Dog vaccines are crucial for safeguarding your canine companion against various infectious diseases. These vaccines stimulate the immune system, preparing it to combat potential threats. The American Animal Hospital Association recognizes certain vaccines as core, including protection against Canine Parvovirus, Canine Distemper, Hepatitis, and Rabies.

Common Side Effects and Reactions to Dog Vaccinations

After a visit to the vet, you might notice some changes in your pup's behavior. These can range from minor to more noticeable reactions. Here are some common side effects:

1. Lethargy

It's not uncommon for puppies to feel a bit tired after vaccinations. Just like humans may experience fatigue after certain medical procedures, dogs can exhibit similar behavior.

2. Crying After Vaccination

Some pups may vocalize their discomfort. Whimpers or cries are their way of expressing that they're not feeling their best.

3. Lumps & Bumps

You might feel lumps or bumps at the injection site. This is a normal reaction as the body responds to the vaccine.

4. Having Trouble Walking After Shots

Occasionally, puppies may seem a bit unsteady on their feet. This is usually temporary and should subside within a short period.

5. Serious Reactions to Vaccines

While rare, serious reactions can occur. Watch out for symptoms like facial or paw swelling, vomiting, diarrhea, or difficulty breathing. If you observe these signs, contact your veterinarian immediately.

Vaccination Schedules and Optional Vaccines

The timing of vaccinations is crucial. Rabies vaccinations, for instance, are often required by law, and the schedule varies by state. In New York, puppies typically receive their rabies shot between 12-16 weeks.


Optional vaccines, such as those for Bordetella and Lyme disease, depend on factors like age, medical history, and lifestyle. Your vet will guide you on which ones are suitable for your furry friend.

Preventing Reactions to Vaccines

While some reactions are normal, severe ones should not be ignored. If your puppy exhibits signs of a more severe reaction, contact your vet promptly. Mild symptoms, such as temporary lethargy, are usually nothing to worry about.

While reactions to vaccines can occur, there are steps you can take to minimize the risk:

1. Follow a proper vaccination schedule: Ensure your puppy receives vaccines at the recommended intervals.

2. Monitor for adverse reactions: Keep a close watch on your puppy after vaccinations and report any unusual symptoms to your veterinarian.

3. Consider optional vaccines: Depending on factors like age, medical history, and lifestyle, additional vaccines such as those for Kennel Cough or Lyme Disease may be recommended.

In the vast majority of cases, reactions are mild and short-lived. It's crucial to be vigilant and seek professional advice if needed.

When to Start Puppy Vaccinations?

Puppy vaccination schedules typically include vaccines for diseases like distemper, hepatitis, parvovirus, and parainfluenza (DHPP). These vaccinations help build immunity and protect your puppy from harmful illnesses.

Remember, vaccines are essential tools in safeguarding your puppy's health and helping them live long, happy lives. With proper care and attention, you can ensure your furry companion stays healthy and energetic for years to come.
