Core Vaccinations for Dogs

Proper vaccination is an essential aspect of ensuring the health and well-being of your furry friend.

Rabies is a deadly viral disease that affects the nervous system of animals and humans. It can be transmitted through the bite of an infected animal. Vaccinating your dog against rabies is not only crucial for their protection but also a legal requirement in many countries. Puppies should receive their first rabies vaccine between 12-16 weeks of age, followed by booster shots every 1-3 years, depending on local regulations.


Canine distemper is a highly contagious viral disease that affects dogs’ respiratory, gastrointestinal, and nervous systems. It is often fatal, particularly in puppies. Vaccination against distemper is typically started at 6-8 weeks of age and continued every 2-4 weeks until the puppy is 16-20 weeks old. Adult dogs should receive a booster shot one year after their initial vaccination, followed by boosters every 3 years.


Parvovirus is another highly contagious and potentially fatal virus that affects a dog’s gastrointestinal tract. It can cause severe vomiting, diarrhea, and dehydration. Puppies are especially vulnerable to parvovirus, and vaccination is crucial for their protection. The vaccination schedule for parvovirus follows a similar pattern as distemper, starting at 6-8 weeks of age and continuing until the puppy is 16-20 weeks old. Boosters are recommended every 3 years for adult dogs.


Infectious canine hepatitis is a viral disease that primarily affects a dog’s liver. It can cause a range of symptoms, including fever, lethargy, loss of appetite, and even liver failure. Vaccination against hepatitis is typically included in a combination vaccine called the DHPP shot, which also protects against distemper, parvovirus, and parainfluenza. The DHPP vaccination is given to puppies following the same schedule as distemper and parvovirus. Boosters are recommended every 3 years for adult dogs.

Additional Vaccinations

In addition to the core vaccinations mentioned above, there are other vaccines available for specific diseases that might be more common in certain regions or based on your dog’s lifestyle. These may include:

  • Leptospirosis: A bacterial infection that can affect both dogs and humans. Leptospirosis vaccines may be recommended if your dog is frequently exposed to wildlife, bodies of water, or areas with high infection rates.
  • Bordetella: Also known as kennel cough, this respiratory infection is common in dogs that frequently interact with other dogs, such as those attending doggy daycare or participating in dog shows. A bordetella vaccine is often required in these environments.
  • Lyme disease: This tick-borne illness is more prevalent in certain regions and may require vaccination if you live in an area with a high risk of exposure to ticks carrying Lyme disease.

Keep in mind that vaccination schedules and recommendations may vary depending on your location, so it’s important to consult with your veterinarian to determine the vaccinations that are necessary for your dog. Vaccines for dogs are an essential part of responsible pet ownership, helping to keep your furry companion healthy and protected from dangerous diseases.

According to a study conducted by the American Veterinary Medical Association, approximately 80% of dogs receive core vaccinations, while only about 55% receive the recommended non-core vaccinations. It highlights the importance of raising awareness about the necessity of vaccinating dogs to ensure their well-being.


  1. What vaccines does my dog need and when?

    Dogs require various vaccinations to protect them from common diseases. The specific vaccines your dog needs depend on factors such as their age, lifestyle, and location. However, the core vaccines recommended for all dogs include rabies, distemper, parvovirus, and hepatitis. Different vaccines have different schedules for initial doses and boosters, so it is vital to consult with your veterinarian to create a vaccination plan for your dog.

  2. At what age should I start vaccinating my dog?

    Puppies usually start receiving vaccinations at around six to eight weeks of age. The timing may vary based on the specific vaccines required and the veterinarian’s recommendation. Vaccination should commence early to ensure puppies are protected as their immunity inherited from their mother begins to wane.

  3. What is the recommended frequency for booster shots?

    Booster shots are necessary to maintain your dog’s immunity against diseases. The frequency of booster shots depends on the vaccine and the guidelines provided by your veterinarian. Most core vaccines require booster shots at one year and then every three years thereafter.

  4. What are the common side effects of vaccinations?

    Vaccinations generally have minimal side effects, but some dogs may experience mild symptoms such as lethargy, soreness at the injection site, or slight fever. These side effects usually resolve within a couple of days. In rare cases, allergic reactions can occur, leading to more severe symptoms. If you notice any unusual or concerning reactions, contact your veterinarian immediately.

  5. Are there any risks associated with vaccinating my dog?

    Vaccinations are generally safe for dogs; however, as with any medical procedure, there are minimal risks. These risks include allergic reactions, adverse effects, or complications. It is essential to discuss your dog’s medical history and any concerns you have with your veterinarian before vaccination.

  6. Can my dog be exempted from certain vaccines?

    In some cases, dogs may be exempted from certain vaccines due to medical conditions, age, or other factors. However, exemptions should be granted by a licensed veterinarian on a case-by-case basis. It is crucial to consult with your veterinarian to determine the most appropriate vaccination plan for your dog.

  7. Is it possible for my dog to get sick even after vaccination?

    Vaccinations significantly reduce the risk of your dog contracting specific diseases, but they do not guarantee complete immunity. Some dogs may still be susceptible to infections even after vaccination. However, vaccinated dogs typically have milder symptoms and a higher chance of recovery compared to unvaccinated dogs.

  8. What happens if I miss a scheduled vaccination?

    It is best to follow the recommended vaccination schedule for your dog. However, if you miss a scheduled vaccination, consult your veterinarian to reschedule it as soon as possible. Delaying or skipping vaccinations can leave your dog vulnerable to diseases, so it is important to maintain an updated vaccination record.

  9. Can I vaccinate my dog at home by myself?

    Vaccinations should always be administered by a licensed veterinarian. Veterinarians have the knowledge, experience, and proper equipment to ensure vaccines are given correctly and safely. They can also provide necessary guidance and advice regarding vaccinations specific to your dog’s needs.

  10. Are there any alternatives to traditional vaccines for dogs?

    Traditional vaccines are the most common and effective method of protecting dogs against diseases. While there are alternative approaches being researched, such as DNA-based vaccines, they are still being developed and may not be widely available. Consult with your veterinarian to determine the best vaccination options for your dog.
