Not every dog vaccine is given once a year. Some are needed annually, while others protect your dog for up to three years at a time. The vaccines given yearly are usually leptospirosis, a core vaccine, along with several non-core lifestyle vaccines. The right schedule depends on your dog’s age, where you live, and how your dog tends to spend its time.
This guide breaks down which vaccines are yearly, which last longer, and how to keep your dog protected.
Core versus non-core vaccines: The short answer
Veterinarians sort dog vaccines into two groups. Understanding the difference makes the yearly question easier to answer.
- Core vaccines are recommended for every dog, no matter their age, breed, or lifestyle, because they guard against widespread and serious diseases.
- Non-core vaccines are added based on your dog’s individual risk, such as time spent at boarding facilities, exposure to ticks, or travel to certain regions.
Which dog vaccines are needed yearly?
The vaccines dogs typically need yearly are leptospirosis, Bordetella, Lyme, and canine influenza. Several core vaccines, including rabies and DHPP, protect your dog for longer than twelve months.
| Vaccine | Typical Frequency |
|---|---|
| Rabies | Every one to three years, depending on state law |
| DHPP (distemper, hepatitis, parvovirus, parainfluenza) | Every one to three years after the first adult booster |
| Leptospirosis | Yearly |
| Bordetella (kennel cough) | Every 6 to 12 months for social dogs |
| Lyme | Yearly in higher-risk regions |
| Canine influenza | Yearly when recommended |
As the table shows, rabies and the DHPP combination are often spaced out to every one to three years once your dog has completed the initial series and first adult booster. The reason some vaccines are needed more often comes down to how long their protection lasts.
Rabies and DHPP produce long-lasting immunity, so boosters can be spaced further apart. Leptospirosis and the non-core vaccines tend to offer shorter windows of protection, which is why they are usually repeated every year.
Your own dog’s plan will be confirmed at each veterinary visit.
Core vaccines explained
Core vaccines cover diseases that are either very common, very serious, or both. Most dogs will receive the following:
- Rabies, which is required by law in nearly every state and protects against a fatal disease that can also affect people.
- DHPP, a single combination vaccine that guards against distemper, hepatitis (adenovirus), parvovirus, and parainfluenza.
- Leptospirosis, which protects against a bacterial infection spread through contaminated water and wildlife, and is now recommended for most dogs on a yearly basis.
Non-core vaccines matched to your dog’s lifestyle
Non-core vaccines are chosen after a conversation about how your dog lives. Your veterinarian will ask about daily routines, travel, and local disease risks before recommending any of these:
- Bordetella, which helps protect against kennel cough and is advised for dogs that visit groomers, daycare, boarding facilities, or dog parks.
- Lyme disease, which is relevant for dogs in tick-heavy areas or those that travel to regions where the disease is common.
- Canine influenza, which is recommended for social dogs and those that spend time around many other animals.
What is titer testing, and does it replace yearly vaccines?
A titer test is a simple blood test that measures the level of antibodies in your dog’s system, and shows whether your dog still has enough immunity from a previous vaccination. If the results show strong immunity, your veterinarian may decide a booster is not needed at that time.
Titer testing is most useful for core vaccines such as DHPP, and it is often considered for senior dogs, dogs with a history of vaccine reactions, or owners who prefer a data-based approach. It does not apply to rabies, since rabies boosters are set by law rather than by antibody levels. Your veterinarian can tell you whether titer testing is a good fit for your dog.
Why yearly visits matter, even when a vaccine is not due
A common misunderstanding is that a year without a booster means a year without a checkup. That is not the case. An annual wellness exam keeps your dog on an accurate schedule, helps to catch small health changes early, and gives your veterinarian the chance to adjust the plan as your dog ages.
Even dogs who stay mostly indoors need core vaccines. Diseases can travel home on shoes, spread during walks, or pass between pets during routine visits, so indoor-only dogs are still at risk without protection.
At Hometown Veterinary Partners, we offer same-day and weekend appointments, so staying current is simple even during a busy week.

Frequently asked questions
Do dogs really need vaccines every year?
Some vaccines are given yearly, while others last one to three years. Your dog will still benefit from a yearly wellness exam even in a year when no booster is due.
Is the rabies vaccine required by law?
In nearly every state, yes. Rabies vaccination is a legal requirement, and staying current protects both your dog and your family.
Do indoor dogs need vaccines?
Yes. Indoor dogs can still be exposed to disease through walks, visitors, other pets, and routine outings, so core vaccines are recommended for them too.
What happens if my dog misses a booster?
Missing a booster can reduce a vaccine’s protection. If your dog has fallen behind, your veterinarian can review the history and set up a simple catch-up plan to restore full coverage.
