Enter your puppy's date of birth and tick the core doses it has already had. The checker shows which vaccinations are done, due soon, or overdue against the US (AAHA) or UK (BSAVA/WSAVA) core schedule.
Compare your puppy's age against the core series schedule. In the US (AAHA), the core DHPP series runs at 6, 9, 12, and 16 weeks, with rabies at 12-16 weeks. In the UK (BSAVA/WSAVA), DHPPi is given at 8 and 10 weeks with a final dose at 16 weeks. If your puppy has passed the age for a dose and not had it, that dose is overdue. The checker above flags each core dose as done, due soon, or overdue based on the date of birth you enter.
If the gap since the last dose is short (under about 6 weeks), the vet will usually continue the series. If the gap is longer, the vet may restart the primary series with two doses 3-4 weeks apart, because a single late dose may not produce reliable immunity if maternal antibodies were still interfering earlier. Never assume partial immunity from an incomplete series. Book a vet appointment to confirm the catch-up plan, particularly for rescue puppies with an unknown history.
No. This tool tracks the core puppy series -- DHPP/DHPPi, rabies in the US, and leptospirosis (core in both the US, following the 2024 AAHA Update, and the UK standard primary course). Non-core (lifestyle) vaccines such as Bordetella (kennel cough), Lyme, and Canine Influenza depend on where you live and how your puppy lives, so there is no single 'up to date' answer for them. Discuss non-core needs with your vet.
Your puppy is considered fully protected roughly two weeks after the final core dose. In the US that is around 18 weeks of age (16-week final dose plus two weeks); in the UK, WSAVA's recommended 16-week final dose means full protection around 18 weeks as well, though many UK vets consider a puppy protected two weeks after the second jab for parvovirus and distemper. Until then, avoid unknown dogs and public ground where parvo risk is higher.
This is not veterinary advice. The site is a general schedule reference, so a sick puppy, a reaction to a vaccine, or a timing decision for one particular animal belongs with your vet and not with us, and it should go there straight away rather than sit in an inbox.
Everything else is fair game. How the primary series is spaced, what a visit tends to cost, what boarding kennels or a state rabies law actually require. Somebody here reads every email, answers what can be answered, and says which guideline or statute the answer came from. We make no promise about how fast.
If a question would help other owners, we may put an anonymised version on the site, and only after you have told us that is fine.
