What Vaccines Do Dogs Need Annually

As a responsible dog owner, you know that it’s up to you to provide the best care your dogs deserve. That includes vaccines that keep your dog protected from serious infectious diseases.  However, with the number of vaccines and doubts around them, it’s only natural that you’re asking yourself “what vaccines do dogs need annually?”. 

Naturally, the best way you can keep your dog vaccinations on schedule is to follow your veterinarian’s instructions. That being said, we’re here to provide you an answer to that perplexing question. 

What Vaccines Do Dogs Need Annually?

Primary vaccination is important if you want to prevent your dog from getting common deadly puppy diseases. According to Dr. Rania Gollakner, BS DVM, recent research has indicated that not all vaccines require yearly boosters.

There are two common categories for vaccination that your vet will suggest. These are core pet vaccines and non-core vaccines. The vaccines dogs need annually are the core pet vaccines. Core pet vaccines are the standard recommended vaccines for pets and commonly administered at an early age with a second shot after a year. Non-core vaccines are administered depending on your dog’s overall health and lifestyle. 

Vaccines can be given to your dog as early as 6 weeks old. Talk to your vet what vaccinations does your dog need and set-up a vaccination schedule that’s convenient for you. Here are some of the common core dog vaccines that your vet would recommend.

Core Dog Vaccines

Core dog vaccines are what vets would usually recommend to your dogs because they’re essential to protect your dogs from life-threatening diseases and pain-causing diseases.

Rabies 1-year

You can start to administer to your dog in one dose as early as 3 months of age. Some states regulate the age at which you need to first administer them. This is a core dog vaccine and they’ll need to get boosters annually. Rabies is fatal to dogs and there are no treatments available for it. That’s why getting your dog vaccinated helps prevent it. 

Rabies 3-year 

While Rabies 3-year is the same as the above, it differs in terms of schedule for vaccination. Your veterinarian will recommend a second vaccination after 1 year. After that, instead of getting boosters annually, you only have to do it every 3 years. 


Distemper is also a core dog vaccine. You need at least 3 doses given between 6 and 16 weeks of age. Puppies a booster 1 year after completing the initial series. After that, your dog needs to get a booster every 3 years. This will protect your dog against an airborne virus that causes Distemper, a disease that may cause permanent brain damage. 


You need at least 3 doses between 6 and 16 weeks of age. Puppies need a booster 1 year after completing the initial series. After that, your dog would need a booster every 3 years. Canine “parvo” is contagious and can cause severe vomiting and bloody diarrhea. If left untreated, it can prove fatal to your dog.

Adenovirus, type 1

You also need 3 doses between 6 and 16 weeks of age. Puppies need a booster 1 year after you complete the initial series and then you’ll need a booster every 3 years. Adenovirus, type 1 can spread via infected urine and feces and can lead to severe liver damage and death.

Adenovirus, type 2 

You also need 3 doses between 6 and 16 weeks of age. Puppies need a booster 1 year after you complete the initial series. You’ll also need a booster every 3 years. This virus can spread via coughs and sneezes. 

Do Dogs Need to be Vaccinated Every Year?

However, there’s also no evidence that annual booster vaccination isn’t beneficial to the majority of pet dogs. In fact, abstaining from some boosters can put your dog at risk. If you want to make sure boosters are necessary for your dog, you need to do a series of blood tests to measure the number of antibodies in your dog.

These tests are usually more expensive and revaccination is more of a suitable choice. The tests also may be stressful for your dog. 

Government regulatory bodies have strict guidelines for vaccines. Manufacturers must prove that their vaccines are safe and effective before they release them on the market and make them usable for your dog.  

At What Age Do You Stop Vaccinating Your Dog?

Dogs older than seven years of age are classified as senior pets. Senior dogs are in the stage of life where the aging process is starting to affect every organ system. Some organs wear out faster and slow down over time so it’s important that you keep track of your dog’s condition.

Keep your vaccinations current. Consult with your veterinarian to determine the proper vaccine schedule that is appropriate for your senior dog’s lifestyle. Commonly, senior dogs will get most vaccinations every three years.

Some vaccines have a shorter duration of immunity. Some examples are leptospirosis, Lyme disease, and kennel cough. Your dog may receive vaccines for these diseases more often, usually every six to twelve months. 

What Happens if Your Dog is Not Vaccinated?

Your dog may have a higher chance of getting diseases that can be fatal to your dog if left untreated. There are a number of studies that show vaccines are effective at protecting dogs that are purposefully exposed to diseases in a controlled situation. 

The wider the community your dog is in, the higher the risk of your pet getting exposed to unwanted sickness. A study in Poland in 2002 shows that vaccinated dogs have a lower chance of getting Distemper compared to unvaccinated dogs. 66% of the infected dogs have never been vaccinated while 22% of the infected dogs were vaccinated at some point. 

Nowadays, the government requires certain vaccinations for your dogs. One example of this is rabies. Rabies is not only harmful to your pets but also for humans. This is why most places around the world require pets to have rabies vaccines to reduce the risk of rabies infection on humans. 


Vaccines for your dog increases its protection against harmful disease and reduces the risks of contracting one. It’s important for you to talk with your veterinarian and discuss what vaccines are needed for your dog’s health and lifestyle. 

Veterinarians administer some vaccines annually, some every 3 years, and others every 6 months. Getting your dog vaccinated may help keep your dog away from potentially deadly diseases.
