Puppy Vaccination Schedule Chart (2026): Every Shot, Every Age

Your breeder or shelter hands you a puppy and a half-remembered verbal summary of "he had his first shots." Then your vet mentions DHPP, bordetella, boosters, and a schedule that stretches to 16 weeks, and you nod like you understand. Here's the chart nobody gave you: which shots your puppy needs, at which ages, and which ones are optional — so you can walk into the vet's office knowing exactly what to expect.

The puppy vaccination schedule chart

Most US vets follow the AAHA (American Animal Hospital Association) guidelines: a series of combination shots starting at 6–8 weeks, boosters every 2–4 weeks, and a final round around 14–16 weeks. Here's the standard version:

• 6–8 weeks: DHPP #1 (distemper, hepatitis/adenovirus, parainfluenza, parvovirus). Often given by the breeder or shelter before you bring the puppy home.
• 10–12 weeks: DHPP #2. This is usually the first round you pay for at your own vet.
• 12–16 weeks: Rabies (required by law in nearly every state — timing varies by state, commonly 12–16 weeks). DHPP #3.
• 14–16 weeks: Final DHPP booster. After this round, your puppy is considered fully protected by the core series.
• 12 months: DHPP and rabies boosters, then on a 1- or 3-year cycle depending on the vaccine and your state law.

The 16-week final shot matters more than most owners realize: maternal antibodies from the mother can block early vaccines from working, which is exactly why the series repeats until 14–16 weeks instead of stopping after one or two rounds.

Core vs non-core: what's actually required

Not every shot on every clinic's price sheet is essential. AAHA divides vaccines into two groups:

Core vaccines (every puppy needs these)

• DHPP — one shot covering distemper, adenovirus (hepatitis), parainfluenza, and parvovirus. Parvo alone kills unvaccinated puppies at terrifying rates; this is the non-negotiable one.
• Rabies — legally required in almost every US state. Your vet will tell you the exact legal timing where you live.

Non-core vaccines (depends on lifestyle and location)

• Bordetella (kennel cough) — recommended if your puppy will attend daycare, boarding, training classes, or dog parks.
• Leptospirosis — recommended in many regions, especially if your puppy will hike, swim, or live where wildlife and standing water are common.
• Canine influenza — worth discussing if your area has had outbreaks or your dog will be in group settings.
• Lyme disease — relevant in tick-heavy regions; your vet knows whether your zip code qualifies.

What the first year of shots costs

Costs vary wildly by region and clinic type, so treat these as planning ranges, not quotes — call your vet for exact numbers:

• Wellness exam per visit: the exam fee applies at each vaccine appointment, and you'll make 3–4 visits in the first few months.
• Each DHPP round: typically the cheapest line item; the exam fee is usually the bigger part of the bill.
• Rabies: inexpensive as a standalone shot; often bundled with the final puppy visit.
• Non-core add-ons: bordetella and lepto add modestly per shot.
• Money-saving options: low-cost vaccine clinics (often run by shelters and humane societies) offer the same core vaccines for a fraction of private-clinic prices — worth checking before you assume the full bill is unavoidable.

5 mistakes first-timers make with the schedule

1. Assuming the breeder's "first shots" finished the job

One round at 6–8 weeks is a start, not a finish. Maternal antibodies can neutralize early doses, so the series must continue to 14–16 weeks. Bring whatever records the breeder gave you to your first vet visit.

2. Taking an under-vaccinated puppy to the dog park

Until about a week after the final 16-week round, avoid high-traffic dog areas: dog parks, pet store floors, and communal potty areas. Parvo survives in soil for months. (Safe socialization is still possible — see our guide on socializing before vaccinations are complete.)

3. Skipping the 12-month booster

The puppy series plus the one-year booster is what locks in long-term immunity. Miss the booster and you're effectively restarting the conversation with your vet.

4. Panicking over mild post-shot sleepiness

Being quiet or slightly sore for 24 hours after vaccines is normal. What's not normal: facial swelling, vomiting, hives, or difficulty breathing — those mean call the vet immediately.

5. Losing the records

Boarding facilities, groomers, training classes, and landlords will all ask for proof of rabies vaccination at minimum. Keep a photo of the certificate on your phone and the paper copy with your important documents.

What to expect at each vaccine appointment

Knowing the rhythm of the visits takes the anxiety out of them — for you and the puppy:

• Check-in and weigh-in: every visit starts with a weight check, since vaccine dosing and growth tracking both depend on it. Bring your question list — the vet tech often collects it here.
• The exam: a quick nose-to-tail physical before any shots, every time. Vets won't vaccinate a puppy who seems unwell, so a mild sniffle can mean rescheduling — that's good medicine, not an inconvenience.
• The shots themselves: most puppy vaccines are given under the skin between the shoulder blades — a quick pinch most puppies barely notice, especially if you're feeding treats at the same moment. Ask if you can be the treat dispenser; it builds the positive association.
• The observation window: many clinics ask you to wait 10–15 minutes after vaccines to watch for rare allergic reactions. Use the time to book the next appointment.
• Aftercare at home: expect a quieter-than-usual puppy for 24 hours and slight soreness at the injection site. A little lethargy is normal; facial swelling, vomiting, or hives are not — call the clinic immediately if you see those.

Bring treats to every appointment and keep the energy calm and boring. Puppies who learn the clinic predicts chicken become adult dogs who walk in happily — and that pays dividends for years.

FAQ

Can my puppy go outside before finishing vaccinations?

Yes, with limits: your own yard is generally fine, but avoid dog parks, pet stores, and areas with heavy unknown-dog traffic until about a week after the final round at 14–16 weeks. Carried outings (in your arms, a carrier, or a stroller) are a great middle ground for socialization.

What does DHPP stand for?

Distemper, Hepatitis (adenovirus), Parainfluenza, and Parvovirus — four diseases covered in one combination shot. It's the backbone of the puppy series.

My puppy is 12 weeks old and hasn't had any shots. Is it too late?

No — it's just late. Your vet will start the series now and adjust the timing. Don't skip the vet visit out of embarrassment; an unprotected puppy is exactly who needs the vet most.

Are there side effects I should watch for?

Mild lethargy or soreness at the injection site for a day is common and normal. Facial swelling, repeated vomiting, or trouble breathing are rare but serious — seek emergency care.
