Quick Answer
Adult dogs need rabies every 1-3 years (legally required) and DHPP every 3 years as core vaccines. Non-core vaccines — bordetella, Lyme, leptospirosis, and canine influenza — require annual boosters if your dog is at risk. Total annual vaccine cost: $50-$200 depending on which shots are needed. Titer testing is an option for some core vaccines.

Core Vaccines for Adult Dogs
Core vaccines are recommended for every dog regardless of lifestyle. They protect against diseases that are widespread, highly contagious, or fatal.
Rabies
Frequency: Every 1-3 years (state law determines the schedule)
Cost: $15-$25 per dose
The rabies vaccine is the only vaccine legally required in all 50 U.S. states. After the puppy series and 1-year booster, most states accept a 3-year rabies vaccine.
DHPP (Distemper, Hepatitis, Parainfluenza, Parvovirus)
Frequency: Every 3 years for adult dogs
Cost: $20-$40 per dose
Also called DA2PP or the "distemper combo." After the puppy series and 1-year booster, AAHA guidelines recommend revaccination every 3 years. Titer testing can be used as an alternative.
Non-Core (Lifestyle) Vaccines
Non-core vaccines are recommended based on your dog's geographic location, lifestyle, and exposure risk. All non-core vaccines require annual boosters.
Bordetella (Kennel Cough)
Frequency: Every 6-12 months | Cost: $15-$30
Required by most boarding facilities, daycares, and groomers. Dogs that socialize with other dogs should stay current.
Leptospirosis
Frequency: Every 12 months | Cost: $15-$30
Increasingly recommended for all dogs due to expanding geographic range. Protects against a bacterial infection that can spread to humans.
Lyme Disease
Frequency: Every 12 months | Cost: $20-$40
Recommended for dogs in tick-endemic areas (Northeast, upper Midwest, Pacific coast). Should be combined with tick prevention products.
Canine Influenza (Dog Flu)
Frequency: Every 12 months | Cost: $25-$50
Recommended for dogs that board, attend daycare, or visit dog parks regularly. Some boarding facilities now require it.
Complete Adult Dog Vaccination Schedule
| Vaccine | Core / Non-Core | Frequency | Cost per Dose |
|---|---|---|---|
| Rabies | Core | Every 1-3 years | $15-$25 |
| DHPP (DA2PP) | Core | Every 3 years | $20-$40 |
| Bordetella | Non-Core | Every 6-12 months | $15-$30 |
| Leptospirosis | Non-Core | Every 12 months | $15-$30 |
| Lyme | Non-Core | Every 12 months | $20-$40 |
| Canine Influenza | Non-Core | Every 12 months | $25-$50 |
Your vet may group vaccines so that not everything is given at the same visit. This spreads out the cost and reduces the chance of vaccine reactions. A typical annual visit includes whichever boosters are due that year plus a physical exam.
Cost Overview: What to Budget Each Year
| Scenario | Annual Cost | Includes |
|---|---|---|
| Core vaccines only | $50-$100 | Rabies (when due) + DHPP (when due) + exam fee |
| Core + bordetella | $75-$130 | For dogs that board or visit groomers |
| Full non-core suite | $150-$250 | All core + bordetella + lepto + Lyme + flu + exam |
| Low-cost clinic | $30-$80 | Core vaccines, no exam fee, walk-in availability |
Many veterinary wellness plans bundle vaccines with annual exams, dental cleanings, and bloodwork for a monthly fee. These can save money if your dog needs multiple services each year.
Titer Testing: An Alternative to Boosters?
A titer test is a blood test that measures your dog's antibody levels against specific diseases. If antibodies are at a protective level, your dog may not need a booster for that disease.
When Titer Testing Works
- • Checking immunity against distemper and parvovirus (DHPP components)
- • Dogs with a history of vaccine reactions
- • Older dogs where owners want to minimize unnecessary vaccines
- • Dogs with immune-mediated diseases
When Titer Testing Does Not Apply
- • Rabies: Legally required regardless of titer results (except in very limited jurisdictions)
- • Bordetella: Boarding facilities require the vaccine, not a titer
- • Leptospirosis: Titer levels do not reliably correlate with protection
- • Canine influenza: No validated titer threshold
Titer tests cost $50-$200 depending on which diseases are tested. While more expensive than a single booster, they can help avoid unnecessary vaccinations for dogs with documented immune responses.
Vaccination for Senior Dogs
Dogs over 7-8 years old are considered seniors (earlier for large and giant breeds). While vaccination remains important for older dogs, the approach may be adjusted.
Rabies: Still Required
Rabies vaccination is legally required throughout your dog's life. Only a few jurisdictions allow medical exemptions for seriously ill animals, and these require veterinary documentation.
DHPP: Consider Titer Testing
Many senior dogs maintain protective antibody levels from previous vaccinations. A titer test can determine if your senior dog truly needs a DHPP booster, avoiding unnecessary immune stimulation.
Non-Core Vaccines: Risk-Based
If your senior dog's lifestyle has changed (less boarding, fewer dog parks, less outdoor time), some non-core vaccines may no longer be necessary. Discuss lifestyle changes with your vet at each annual visit.
Immune Health Considerations
Dogs with cancer, autoimmune diseases, or on immunosuppressive medications may need a modified vaccine schedule. Your vet will weigh the risk of disease exposure against the risk of vaccine reactions.
What If You Miss a Booster?
Life happens, and sometimes vaccine boosters get delayed. Here is what to expect:
| Vaccine | Slightly Overdue (weeks) | Significantly Overdue (months+) |
|---|---|---|
| Rabies | Single booster restores protection | Single booster, but legally your dog is considered "unvaccinated" until given |
| DHPP | Single booster usually sufficient | Single booster; titer test can confirm immunity |
| Bordetella | Single booster | May need to restart series (vet discretion) |
| Lepto / Lyme / Flu | Single booster usually OK | Vet may recommend restarting the 2-dose initial series |
The most important thing is to get back on schedule as soon as possible. Your vet will determine whether a single booster or a restart is needed based on how long your dog has been overdue.
