Puppy Vaccination Schedule: What, When, and Why

Vaccines protect your puppy from diseases that are common, expensive, and often deadly. Your vet tailors the plan to your area and lifestyle, but here's the typical roadmap so you know what to expect.

Core vs. Non-Core

Core vaccines are recommended for essentially all dogs: distemper, adenovirus (hepatitis), parvovirus (often combined as "DAPP" or "DHPP"), and rabies. Non-core vaccines depend on risk — leptospirosis, Bordetella (kennel cough), canine influenza, and Lyme — and are wise for dogs who board, go to daycare, hike, or live where those diseases circulate.

The Typical Timeline

  • 6–8 weeks: first DAPP.
  • 10–12 weeks: second DAPP; non-core vaccines may begin based on risk.
  • 14–16 weeks: final DAPP and rabies (rabies timing also depends on local law).
  • ~1 year: boosters, then every 1–3 years depending on the vaccine and local rules.
Why the last booster (≈16 weeks) matters most: antibodies from mom can block earlier vaccines from "taking." The series is spaced so that at least one dose lands after maternal antibodies fade. That's why you can't skip the final puppy booster.

Keep Your Puppy Safe During the Series

Until about a week after the final round, avoid high-risk spots like dog parks and pet-store floors where parvo can linger. You can still socialize safely — carry your puppy in busy places, host calm visits with vaccinated adult dogs, and attend a reputable puppy class that requires up-to-date shots.

After a Shot

Mild tiredness or a little soreness for a day is normal. Call your vet promptly for facial swelling, hives, repeated vomiting, or trouble breathing — rare reactions that need quick care.
