Question 1

When do puppies get their first shots?

Accepted Answer

The core DAP vaccine (distemper, adenovirus, parvovirus, often with parainfluenza) typically starts at 6-8 weeks of age. Per the 2022 AAHA guidelines it is then repeated every 2-4 weeks, with the final puppy dose given at 16 weeks or older. Deworming starts even earlier, at 2 weeks.

Question 2

What is the full puppy vaccine schedule?

Accepted Answer

A representative schedule: DAP at 8, 12, and 16 weeks (the last dose must be ≥16 weeks); rabies as a single dose between 12 and 16 weeks per local law; and 1-year boosters for both. Deworming runs at 2, 4, 6, and 8 weeks, then monthly through 6 months. Enter your litter's birth date above to get exact calendar dates.

Question 3

Why does the last DAP shot have to be at 16 weeks or older?

Accepted Answer

Antibodies a puppy absorbs from the dam's colostrum can neutralize a vaccine before the puppy's own immune system responds. These maternal antibodies fade at different ages in different puppies, but are usually gone by about 16 weeks, so a final dose at ≥16 weeks ensures the series 'takes.' Some veterinarians add a dose at 18-20 weeks for extra certainty.

Question 4

What is the puppy deworming schedule?

Accepted Answer

The Companion Animal Parasite Council (CAPC) recommends deworming at 2, 4, 6, and 8 weeks of age, then monthly until 6 months. Roundworms and hookworms are passed from the dam to nursing puppies, so early, repeated treatment is standard, followed by year-round parasite prevention.

Question 5

Which puppy vaccines are core vs. optional?

Accepted Answer

Core (recommended for every dog): DAP and rabies. Non-core/lifestyle (given based on risk, ask your vet): Bordetella (kennel cough), leptospirosis (now recommended for most dogs), Lyme (tick regions), and canine influenza (boarding/showing). The generator lists optional vaccines separately so you can discuss them with your veterinarian.

Question 6

Can puppies go outside or meet other dogs before they're fully vaccinated?

Accepted Answer

Until about a week after the final DAP dose (≥16 weeks), puppies are vulnerable to parvovirus and distemper. Avoid dog parks, pet stores, and unknown dogs' waste. Controlled socialization with healthy, vaccinated dogs in clean settings is still important, the behavioral benefits are weighed against the small infection risk. Discuss the balance with your veterinarian.
