Adult Dog Vaccine Schedule: What's Due and When

Once your dog finishes the puppy series, boosters keep protection strong. How often depends on the vaccine, your dog's lifestyle and your local laws. Your vet will make the final call.

Core boosters

Rabies: every one or three years, depending on the vaccine and local law

Distemper, adenovirus and parvovirus: often every three years after the initial series and booster, as the vaccine label and vet advise. Parainfluenza is not automatically on the same core interval

Leptospirosis is core under AAHA's updated guidance; following the initial two-dose series, boosters are typically yearly as directed by the product and veterinarian

Non-core vaccines, based on lifestyle

Bordetella (kennel cough): often every six to twelve months for dogs that board, go to daycare or visit groomers

Lyme disease: yearly for dogs in tick-prone areas
Canine influenza: yearly for dogs at risk

What changes how often

Boarding or daycare, travel, hiking, living near wildlife or standing water, your dog's age and health, and local outbreaks all play a role.

Senior dogs and health conditions

Ask your vet whether any changes are needed for older dogs or those with chronic illness.

Titer tests

Antibody tests can inform some individual vaccine decisions, but generally do not replace legally required rabies vaccination or a facility's required certificates. Confirm requirements before booking.
