Adult Dog Vaccination Schedule: Boosters & Annual Shots
Once your dog completes the puppy vaccine series, they still need regular booster shots throughout adulthood to maintain protection against serious diseases. This complete adult dog vaccination schedule covers which core and non-core vaccines are needed, how often, and how to track them so nothing is ever missed.
Adult Dog Vaccine Schedule at a Glance
| Vaccine | Type | Frequency |
|---|---|---|
| DHPP (Distemper, Hepatitis, Parvo, Parainfluenza) | Core | Every 1–3 years |
| Rabies | Core | Every 1 or 3 years (by law) |
| Bordetella (Kennel Cough) | Non-Core | Annually (or every 6 months for high-risk dogs) |
| Leptospirosis | Non-Core | Annually (recommended for outdoor dogs) |
| Lyme Disease | Non-Core | Annually (tick-endemic areas) |
| Canine Influenza (H3N2 / H3N8) | Non-Core | Annually (dogs in kennels, dog parks, shows) |
Core Vaccines for Adult Dogs
Core vaccines are recommended for all adult dogs regardless of lifestyle, because the diseases they prevent are serious, widespread, or transmissible to humans (zoonotic).
DHPP (Combination Vaccine)
Protects against Distemper, Hepatitis (Adenovirus-2), Parvovirus, and Parainfluenza. After the 12–16 month puppy booster, this is given every 1–3 years. The 3-year version (often labeled DA2PP-3) is widely accepted and reduces the frequency of vet visits.
Rabies
Required by law in most regions. After the initial puppy dose and 12-month booster, subsequent doses are given every 1 or 3 years depending on the vaccine and local regulations. Always check your municipality's requirements.
Non-Core Vaccines for Adult Dogs
Non-core vaccines are recommended based on your dog's lifestyle, geographic location, and individual risk factors. Discuss with your vet which of these are appropriate for your dog.
Bordetella bronchiseptica (Kennel Cough)
Recommended for any dog that interacts with other dogs — at dog parks, boarding facilities, groomers, or training classes. Given annually; some vets recommend every 6 months for high-exposure dogs.
Leptospirosis
Recommended for dogs with outdoor exposure, especially near water sources or in urban areas with wildlife. This is a zoonotic disease that can also affect humans. Given annually.
Lyme Disease (Borreliosis)
Recommended for dogs in tick-endemic regions or those who spend time in wooded, grassy, or rural areas. Given annually alongside a tick prevention program.
Canine Influenza (H3N2 & H3N8)
Recommended for dogs in high-contact environments like kennels, dog shows, or doggy daycares. Given annually. The bivalent vaccine protects against both strains.

Frequently Asked Questions
How often does an adult dog need vaccines?
Core vaccines like DHPP are given every 1–3 years in adult dogs, depending on the vaccine brand and your vet's protocol. Rabies is required every 1 or 3 years depending on local law and the vaccine used. Non-core vaccines like Bordetella and Leptospirosis are typically given annually.
What core vaccines does an adult dog need?
The two essential core vaccines for adult dogs are DHPP (Distemper, Hepatitis, Parvovirus, Parainfluenza) and Rabies. These protect against serious, potentially fatal diseases and are recommended for all dogs regardless of lifestyle.
Does my indoor dog still need annual vaccines?
Yes. Even indoor dogs can be exposed to airborne diseases like distemper and parvovirus, or to rabies through contact with wildlife. Core vaccines are recommended for all dogs. Your vet can assess whether non-core vaccines are necessary based on your dog's specific lifestyle and risk.
What is a dog titer test and can it replace vaccines?
A titer test measures the level of antibodies in your dog's blood to determine whether they still have protective immunity from previous vaccines. Some vets accept titer tests as an alternative to automatic revaccination for DHPP, but not for rabies (which is legally mandated in most regions).
What vaccines does my dog need every year?
Annual vaccines typically include: Bordetella (kennel cough), Leptospirosis (if at risk), Lyme disease (if in tick-endemic areas), and Canine Influenza (if your dog is in group settings). Core vaccines (DHPP and Rabies) are on 1–3 year cycles depending on vaccine type and local regulations.
What is the best app to track my dog's vaccination schedule?
PetNoter is a free pet care app for Android and iOS that lets you log every vaccination, set reminders when boosters are due, and keep all your dog's health records in one organized place.
