Puppy Vaccination Schedule Chart: What Your Vet Won't Always Explain

[Published: August 14, 2026 | Last updated: August 14, 2026] | 9 min read

TL;DR

• Puppies need three to four rounds of core vaccines between 6 and 16 weeks, spaced 3-4 weeks apart (American Animal Hospital Association, 2024).
• The core vaccines are DHPP (distemper, hepatitis, parainfluenza, parvovirus) and rabies; rabies is given once, usually at 12-16 weeks.
• Untreated parvovirus kills roughly 91% of infected puppies, which is why finishing the full series matters more than any single shot (Sürer et al., 2023).
• A full puppy vaccine series typically costs $75-$250 at a general practice clinic, less at low-cost or shelter clinics (PetCare AI, 2026).
• After the 1-year booster, core vaccines move to every 3 years; non-core vaccines like leptospirosis and Bordetella are usually annual.

What Is a Puppy Vaccination Schedule?

A puppy vaccination schedule is the set timeline of shots a puppy needs between about 6 weeks and 16 weeks of age to build immunity before its mother's antibodies wear off. It is not one visit. It is a series, because a single dose given too early can be blocked by maternal antibodies still circulating in the puppy's blood.

The American Animal Hospital Association (AAHA) publishes the guidelines most US vets follow, last revised in 2024 (American Animal Hospital Association, 2024). Individual clinics can adjust the exact spacing, but the underlying structure is the same everywhere: start around 6-8 weeks, repeat every 3-4 weeks, and finish no earlier than 16 weeks.

The reason 16 weeks is the cutoff, not just a rough guideline, is that maternal antibodies can still neutralize a vaccine dose in some puppies up to that age (Sürer et al., 2023). A puppy that finishes its series at 12 weeks instead of 16 may still be unprotected.

Puppy Vaccination Schedule Chart by Age

Here is the standard chart most US vets use, built on AAHA core vaccine guidelines.

A puppy that starts the series late (say, at 10 weeks) still needs the full number of doses, spaced 3-4 weeks apart, finishing no earlier than 16 weeks. Late starts do not skip doses; they shift the whole chart later.

New Puppy Vaccination Schedule: What Happens at Each Vet Visit

A new puppy vaccination schedule usually means four vet visits in the first four months, not one. Each visit does more than deliver a shot: your vet also checks weight gain, deworms if needed, and screens for early signs of illness.

First visit (6-8 weeks): The vet gives the first DHPP dose and typically runs a fecal test for intestinal parasites. This is also when most owners start a flea and heartworm prevention plan, since maternal protection against parasites fades on a similar timeline to disease immunity.

Second visit (10-12 weeks): The second DHPP dose is given. If your puppy will be around other dogs regularly (dog parks, daycare, boarding), this is when Bordetella or canine influenza is usually added, based on local risk.

Third visit (12-16 weeks): Rabies is given, timed to state law, along with the third DHPP dose. If leptospirosis was started at visit two, its second dose is due here too.

One-year visit: Your vet gives the DHPP and rabies boosters. This visit resets the clock: after this point, core vaccines shift to the 3-year (DHPP) and 1-3 year (rabies) adult schedule shown in the chart above.

Missing a visit does not mean starting over, but it does mean re-spacing the remaining doses. Call your vet rather than guessing; they will tell you whether the puppy needs an extra dose based on how much time has passed.

Core vs. Non-Core Puppy Vaccines Explained

Core vaccines are the ones every puppy needs, regardless of breed, size, or lifestyle. Non-core vaccines are added based on where you live and how your puppy will spend its time.

Core vaccines (every puppy gets these):

• Distemper: an often-fatal virus affecting the respiratory, digestive, and nervous systems.
• Adenovirus (hepatitis): causes infectious canine hepatitis, bundled into the same DHPP shot.
• Parainfluenza: a contagious respiratory virus, also bundled into DHPP.
• Parvovirus: a severe intestinal virus with a roughly 91% fatality rate in untreated puppies (Sürer et al., 2023).
• Rabies: fatal once symptomatic, transmissible to humans, and required by law in nearly every US state.

Non-core vaccines (lifestyle- and region-dependent):

• Leptospirosis: recommended where puppies may contact standing water or wildlife urine; needs annual boosters.
• Bordetella (kennel cough): recommended for puppies attending daycare, boarding, or group training classes.
• Canine influenza: recommended in regions with recent outbreaks or for puppies in high-contact settings.
• Lyme disease: recommended in the Northeast and Upper Midwest US, where tick exposure is higher.

Your vet decides which non-core vaccines apply based on your specific location and your puppy's planned activities, not a general rule.

What Puppy Vaccines Cost in the US

A full puppy vaccine series usually runs $75-$250 at a general practice clinic for all core doses combined, with low-cost and shelter clinics offering individual shots for as little as $10-$30 (PetCare AI, 2026). Prices run highest in major metro areas and at AAHA-accredited hospitals, which carry stricter facility and equipment standards.

Many clinics bundle the full puppy series into a discounted package rather than billing each visit separately. Ask your vet about package pricing before the first visit; it is often cheaper than paying per-visit.

Spay/neuter, microchipping, and deworming are typically billed separately from the vaccine series itself, even when scheduled on the same day.

Common Mistakes to Avoid With a Puppy Vaccination Schedule

• Stopping the series early because the puppy "seems fine": A puppy can look healthy and still be unprotected until the final dose at 14-16 weeks. Finish all rounds even if nothing seems wrong.
• Taking an unvaccinated puppy to dog parks before the series is done: Parvovirus survives in soil and on surfaces for months. Wait until the vet confirms the series is complete before high-exposure outings.
• Assuming one rabies shot covers the puppy for life: Rabies needs a booster within a year, then every 1-3 years depending on state law.
• Switching vets mid-series without records: Bring the vaccine record card to every visit, including a new vet. Missing dates lead to unnecessary re-starts or gaps in protection.
• Skipping non-core vaccines without asking: A puppy heading into daycare without a Bordetella vaccine can be turned away or, worse, get sick. Ask what your specific routine requires.

Frequently Asked Questions About Puppy Vaccination Schedules

What is the standard puppy vaccination schedule?

Most US vets follow a 3-4 round DHPP series starting at 6-8 weeks, repeated every 3-4 weeks, with a single rabies dose at 12-16 weeks. The series is not complete until the final DHPP dose, given no earlier than 16 weeks.

How much does a full puppy vaccination schedule cost?

A complete series typically costs $75-$250 at a general practice clinic, or as little as $10-$30 per shot at low-cost and shelter clinics (PetCare AI, 2026). Costs vary by region and clinic type.

What happens if I miss a scheduled puppy vaccine visit?

The series does not restart, but the remaining doses need to be re-spaced. Call your vet with the date of the last shot so they can calculate the new timing rather than guessing.

Can a puppy go outside before finishing its vaccination schedule?

Supervised time in your own yard is generally fine. High-exposure areas like dog parks, pet stores, and group classes are best avoided until the full series is complete, since parvovirus can survive in soil for extended periods.

Do puppies need non-core vaccines like Bordetella or leptospirosis?

It depends on your location and lifestyle. Puppies attending daycare or boarding often need Bordetella; puppies in areas with standing water or wildlife exposure often need leptospirosis. Ask your vet which non-core vaccines fit your specific routine.

When does a puppy vaccination schedule switch to the adult schedule?

After the 1-year booster visit. From that point, DHPP typically moves to every 3 years and rabies to every 1-3 years, depending on state law (American Animal Hospital Association, 2024).

Key Takeaways

• A puppy vaccination schedule is a series of 3-4 DHPP doses plus one rabies dose, finishing no earlier than 16 weeks.
• Untreated parvovirus has a fatality rate near 91% in puppies, which is the main reason to complete every round on schedule (Sürer et al., 2023).
• Core vaccines apply to every puppy; non-core vaccines depend on your region and your puppy's lifestyle.
• Full series costs typically run $75-$250, with lower-cost options available through shelter and community clinics.
• After age one, the schedule shifts to 3-year DHPP boosters and rabies boosters set by state law.
