Socialize now — safely — the behavior window is closing
Professional guidance
AVSAB: begin socialization before the series is complete. Puppy class is appropriate 7+ days after the first vaccine set. Carry to new places; avoid dog parks and unknown-dog areas until fully vaccinated.
This week: allowed vs hold
Professional guidance
Allowed: carried outings, friends' healthy vaccinated dogs, puppy class. Hold: dog parks, pet-store floors, unknown-dog areas (parvo risk).
Missed a dose?
Fact
Core (modified-live) vaccines resume with a single catch-up dose — you don't restart. Two-dose killed vaccines (e.g. leptospirosis) restart only if the gap exceeds 6 weeks. Confirm with your vet.
Watch for
  • Lethargy, vomiting, or bloody diarrhea in an unvaccinated puppy → emergency vet (parvo).
Assumptions: Your veterinarian's individual schedule always takes priority over this general calendar.

⚠ Key Vaccination: Canine Parvovirus (CPV) — 2022 AAHA Canine Vaccination Guidelines: minor: WSAVA 2024 states revaccinate every 3-4 wk until 16 wk (vs AAHA 2-4 wk until >16 wk) — see EV-D30-08
⚠ 2024 guidelines for the vaccination of dogs and cats (WSAVA Vaccination Guidelines Group): none (distinguishes vaccine type; nuances the general 'no restart' rule)
How this was decided — all 5 sources, tiers & dates
Rules fired: core series: start 6-8wk, q2-4wk until >16wk (18-20wk if high parvo risk); socialization window = first 3 months; classes after first vaccine set + 7 days

Why this answer

A puppy's core vaccine series runs from 6–8 weeks, repeating every 2–4 weeks until after 16 weeks (18–20 in high-risk areas), with rabies from 3 months. Crucially, socialization should begin before the series is complete — puppy class is appropriate about 7 days after the first vaccine set — because the behavior window closes around 12–14 weeks.

When this doesn’t apply

  • Adult dogs past the puppy series use routine booster schedules instead.
  • Your veterinarian's individual schedule always takes priority over this general calendar.

What changes the answer

  • Local parvo risk can push the final dose to 18–20 weeks.
  • Country and state/province set rabies timing and law.
  • Missed doses branch by vaccine type — core vaccines resume with one dose; two-dose killed vaccines restart if the gap exceeds 6 weeks.

Common questions

What did you do for socialization before your puppy was fully vaccinated?
Begin during the series, safely: carry to new places, invite healthy vaccinated dogs, and start puppy class about 7 days after the first vaccine set. Avoid dog parks and unknown-dog areas until fully vaccinated. AVSAB calls early socialization the standard of care.
When can my puppy go outside?
For safe socialization, right away in low-risk settings (carried, friends' vaccinated dogs, class). For dog parks and public high-traffic areas, wait until the series is complete around 16 weeks.
