A puppy's first year of vaccinations runs on a strict clock. The series starts at 6 to 8 weeks of age, repeats the same core vaccines every 2 to 4 weeks, and closes with a final dose at 16 weeks or later. Most new owners hold this entire plan on a paper card from the breeder, watch the puppy look half grown before the series ends, and then field calls from daycare asking for proof of every dose.
This guide walks the full puppy immunisation schedule month by month, from first shots to full protection. It covers what happens at each vet visit, why the same vaccine gets repeated, when protection becomes full, where a puppy can safely go in between, what the series costs, and how to keep the record straight when the dates start to pile up.
When Does a Puppy Get Its First Shots?
A puppy gets its first shots at 6 to 8 weeks of age, usually before it comes home. Breeders and shelters give the first combination dose, then hand over a vaccine card listing the date, the product and the lot number.
The AAHA 2022 Canine Vaccination Guidelines define 3 core vaccines for puppies in the US: the distemper, adenovirus and parvovirus combination sold as DAP or DHPP, rabies, and leptospirosis. Leptospirosis moved onto the core list in the 2022 edition. Rabies is also fixed in state law, with products labeled for use from 12 weeks of age.
A puppy that arrives with a vaccine card starts its series from the last recorded dose. Ask the breeder or shelter for written proof of every dose already given. The vet then continues the series from that entry instead of restarting it, which saves a visit and keeps the intervals intact.
What Happens at Each Puppy Vet Visit?
Each puppy vet visit pairs vaccine doses with a physical exam, and the typical US clinic pattern fits the series into 3 to 4 visits between 6 and 16 weeks, plus a booster at 12 months. Vets adjust the exact weeks to the puppy's start date, local disease risk and state rabies law, so treat the pattern below as the typical clinic pattern rather than a rule.
Week 6 to 8. The first DAP dose arrives with the puppy's first full physical exam. Most vets run a fecal test at the same visit and start deworming on the Companion Animal Parasite Council schedule: every 2 weeks until 12 weeks of age, then monthly until 6 months.
Week 10 to 12. The second DAP dose lands 2 to 4 weeks after the first. The leptospirosis series also starts here as 2 doses spaced 2 to 4 weeks apart. Lifestyle vaccines, including Bordetella, Lyme and canine influenza, may begin at this visit based on the vet's risk assessment.
Week 14 to 16. The third DAP dose arrives, and rabies is given per state law. Rabies products carry labels for use from 12 weeks of age, so this visit often combines both injections.
Week 16 to 20. Many vets close the series with a final DAP dose at or after 16 weeks. This is the dose maternal antibodies can no longer block, and it anchors the protection that follows.
Twelve months. The combination vaccine and rabies get boosters within 1 year of the final puppy dose. After that, the combination vaccine moves to a 3-year cycle, leptospirosis stays annual, and rabies runs the cycle state law sets.
The table below summarizes the typical puppy immunisation schedule by age, what each visit delivers, and why the timing matters.
| Puppy age | What is given | Why it matters |
|---|---|---|
| 6 to 8 weeks | First DAP dose, first full exam, fecal test, first deworming | Opens core protection and screens for parasites |
| 10 to 12 weeks | Second DAP dose, first leptospirosis dose, optional Bordetella, Lyme or canine influenza | Continues the series and covers lifestyle risks |
| 14 to 16 weeks | Third DAP dose, rabies per state law | Rabies becomes a legal requirement and the series nears its close |
| 16 to 20 weeks | Final DAP dose at or after 16 weeks | First dose maternal antibodies cannot block |
| 12 months | DAP and rabies boosters | Starts the adult cycles: DAP every 3 years, leptospirosis annual |

Why Does a Puppy Need Repeat Doses of the Same Vaccine?
A puppy needs repeat doses because maternal antibodies from the mother's milk neutralize early vaccines. Those antibodies protect the puppy against distemper and parvovirus in its first weeks. They also clear vaccine particles the same way, so an early dose can disappear before the puppy's immune system ever registers it.
The AAHA 2022 Canine Vaccination Guidelines put numbers on the fade window. Maternal antibodies against distemper drop by about 12 to 14 weeks of age. Antibodies against parvovirus persist to 13 to 15 weeks or longer.
That fade window explains the dosing rules. The guidelines require at least 3 doses of the combination vaccine between 6 and 16 weeks, spaced 2 to 4 weeks apart, with the final dose at 16 weeks or later. The interval matters more than the count: a dose given too early gets neutralized, while a dose placed after the antibodies fade trains the puppy's own immune system to respond on its own.
When Is a Puppy Fully Vaccinated?
A puppy counts as fully vaccinated 1 to 2 weeks after the final dose of the series, which lands between 16 and 20 weeks of age for most puppies. Protection stays partial until that point, even after 3 or 4 recorded doses.
Two things stretch the finish line. In areas with high parvovirus or distemper risk, the AAHA 2022 Canine Vaccination Guidelines let vets extend the series to 18 to 20 weeks. A series that starts late, or pauses for illness, also shifts every date after it.
The final dose starts the booster calendar as well. The 12-month booster counts from that injection, which is why the vaccine card date, not the adoption date, drives the adult schedule.
Where Can a Puppy Go Before the Series Is Finished?
Before the series finishes, a puppy can go onto low-risk ground: its own yard, homes of known fully vaccinated adult dogs, carried outings and clean puppy classes. Dog parks and public floors wait until 1 to 2 weeks after the final dose.
The question matters because the socialization window closes around 14 to 16 weeks of age. The American Veterinary Society of Animal Behavior states that safe socialization before the vaccine series is complete belongs in standard care, because behavioral problems carry more risk than disease for most puppies.
4 outing types carry low risk before the final dose:
- The puppy's own yard, provided unknown dogs have had no access to it
- Homes of known, fully vaccinated adult dogs
- Carried outings in arms or a carrier, with no ground contact
- Puppy classes that require at least one combination vaccine dose and disinfect their floors
4 places hold risk until 1 to 2 weeks after the final dose:
- Dog parks
- Pet store floors
- Public sidewalks with unknown dog traffic
- Veterinary waiting room floors
Parvovirus survives in soil for months. Ground that unknown dogs use is the real risk, more than people, air or a ride in the car.
How Much Do Puppy Shots Cost?
Puppy shots commonly cost $20 to $60 per injection at US clinics. CareCredit places the national average at roughly $27 to $96 per vaccine depending on vaccine type and location, and Petworks reports the $20 to $60 range as typical per puppy shot. A complete first-year series with exams lands most owners in the low hundreds of dollars.
3 price structures exist across US clinics:
- Per-vaccine pricing at $20 to $60 per shot, plus exam fees
- Staged puppy packages, for example $45, $65 and $70 bundles that add deworming and parasite prevention
- Low-cost vaccine clinics run by cities, shelters and retail pharmacies
Lifestyle vaccines move the total. Bordetella, Lyme and canine influenza each add an injection to the invoice, and leptospirosis requires 2 doses in year one. Prices also vary by clinic and region, so call ahead for the package price before booking the series.
How Do You Track a Puppy Immunisation Schedule Without Losing It?
One puppy profile that stores every dose date tracks the schedule without losing it, because the schedule itself works against memory. The series spans 3 to 4 visits in 4 months, each vaccine runs its own interval, and then the cycles split: the combination vaccine moves to every 3 years, leptospirosis stays annual, and rabies runs the cycle state law sets. Meanwhile, the first entries often sit on a paper card the breeder or shelter filled out.
güdpet stores the whole first year in one place. Each vaccine gets its own dose history with dates, smart reminders fire on each vaccine's cycle rather than one blanket alert, and photos of the breeder's vaccine card preserve the entries made before adoption. The record then shares with the vet, groomer or boarding facility through Digital Pet ID.

Frequently Asked Questions
How many vet visits does a puppy need for shots?
A puppy needs 3 to 4 visits between 6 and 16 weeks for the core series, plus rabies at 12 to 16 weeks and a booster within 1 year of the final dose. Exams and fecal tests happen at the same visits. The güdpet features page shows how to log each visit as a dose entry with its own date.
Can a puppy go outside before fully vaccinated?
Yes, on low-risk ground. Own yards, homes with vaccinated adult dogs and carried outings stay safe; dog parks and public ground wait until 1 to 2 weeks after the final dose. Learning how to keep pet vaccination records online marks the exact date public outings open.
What happens if a puppy misses a shot?
Call the vet and resume the series from the last recorded dose. The 2 to 4 week interval matters more than an exact count, and a visible dose history lets the vet restart the clock correctly. The guide on how to organize pet health records keeps that history readable at the clinic.
Do puppy shots cover kennel cough?
Core puppy shots do not cover kennel cough. The Bordetella vaccine adds that protection, and most daycares, boarding facilities and puppy classes require it. Facilities ask for dated proof, and a digital pet ID carries the Bordetella entry without the paper card.
Are puppy boosters needed every year?
Not every vaccine boosts annually. After the 1-year booster, the combination vaccine runs every 3 years, leptospirosis stays annual, and rabies follows the 1-year or 3-year cycle state law sets. Keeping the dates in one place, as covered in how to keep pet vaccination records online, prevents missed cycles.
From first shots at 6 to 8 weeks to full protection after the 16-week dose, the puppy immunisation schedule runs on dates the owner holds, not the vet's memory. güdpet keeps every dose, reminder and shared record in one puppy profile, with plans and pricing on güdpet pricing. Photograph the breeder's card today, log the first dose, and let per-vaccine reminders carry the rest of the year.
