Health and vet care
When should a puppy get a rabies shot?
In the US, a puppy gets its first rabies shot at 12 weeks (3 months) of age or older, and state or local law sets the latest age. A booster follows one year later. After that, boosters every 1 or 3 years depend on the vaccine and local rules, so check with your vet.
When do puppies get rabies shots?
Licensed rabies vaccines for dogs in the US are labeled for puppies 3 months of age and older, and CDC advises that most dogs should not be vaccinated before 12 weeks. The Puppy Vaccination Schedule shows a 12 to 16 week window as a planning example, not a legal deadline.
The latest age is set by law, not by the vaccine. Rabies vaccination is required in many places, and the rules on the first shot, boosters and overdue doses can differ by state, county or city. Ask your vet or local health department what applies where your puppy lives.

When is a puppy protected after a rabies shot?
CDC guidance treats an animal as immune 28 days after its first rabies shot. After a later booster, an animal with a vaccine history counts as vaccinated straight away.
If your puppy is bitten by or fights with a wild animal or an unknown dog, call your vet or local health department straight away, whatever the vaccine dates say.

Rabies shot timing at a glance
The table sums up first-year timing in each country PupCalendar covers. Rules can change, so confirm with your vet before you act.
| Country | First rabies shot | What else to know |
|---|---|---|
| US | 12 weeks (3 months) or older; the latest age is set by state or local law | Booster 1 year later, then every 1 or 3 years by vaccine and law |
| Canada | 3 to 4 months in CVMA kennel guidance, unless your vet advises otherwise | Provinces, territories and towns set their own rules |
| UK | Given for travel, from 12 weeks of age | Microchip first or on the same day; wait 21 full days after the first shot before travel |
| Australia | Australia is free of rabies | Ask your vet before travel; import rules apply to dogs coming in |

How do I plan my puppy's rabies shot?
Enter the birth date in the Puppy Vaccination Schedule and choose your country. For a US puppy born in September 2026, the planner shows a rabies window from 12 to 16 weeks.
Worked example
Birth ; US; rabies shot given at 12 weeks
- Rabies planning window (12 to 16 weeks)
- to
- Treated as immune (28 days after the first dose)
- First rabies booster (1 year after the dose)
Window checked against the Puppy Vaccination Schedule; the 28-day and booster dates count from the example dose. Local law may differ.
Time the booster from the date the rabies shot was actually given, not from the last combination shot. If the first dose is given at the start of the window, the 28-day mark and the one-year booster fall on the dates shown.

Do puppies need rabies boosters?
Yes. AAHA recommends a booster one year after the first rabies shot, whatever the vaccine type or the puppy's age at the first dose. This protects any puppy that did not respond to the first shot.
After that, US rabies vaccines come in 1-year and 3-year types, and local law can set the interval. Blood antibody tests do not replace the rabies vaccine, and only some places allow exemptions, so talk to your vet about any health concern.

Rabies vaccination is legally required in many places, and age, booster timing and overdue rules may be set by local, state or provincial law. Licensed dog vaccines are inactivated, licensed for puppies 3 months and older, and come in 1 and 3 year types. A booster is advised 1 year after the first dose. Exemptions exist only in some places, and antibody tests do not replace vaccination.
Most dogs should not be vaccinated before 3 months (12 weeks) of age. An animal counts as immune 28 days after its first vaccination, and as vaccinated straight after a booster if it has a vaccine history. Vaccinate according to local laws; schedules vary by product and state.
Appendix D.3.1.4: unless a veterinarian advises otherwise, puppies receive their first rabies vaccine between three and four months of age, with a booster one year later. This is kennel guidance, not a provincial legal deadline.
For pet travel: the vet needs proof the pet is at least 12 weeks old; the pet must have a microchip fitted before or at the same time as the rabies vaccination; wait at least 21 full days after the first vaccination before travel.
