Dog vaccination schedule
The usual protocols in the United Kingdom, the United States, Canada and Australia, vaccine by vaccine — with the ages of the primary course and the booster rhythm. For guidance only.
These schedules are indicative. A dog's protocol depends on its age, lifestyle, region and health: your vet always has the final say.
United Kingdom
| Vaccine | Primary course | First booster | Then |
|---|---|---|---|
| DHPthe core dog combo: distemper, hepatitis and parvovirus — first booster at 1 year, then every 3 years | 8 weeks, 11 weeks | 1 year after the primary course | every 3 years |
| Leptospirosisbacteria spread by rodent urine and standing water — yearly booster | 8 weeks, 12 weeks | 1 year after the primary course | every year |
| Kennel coughinfectious cough (Bordetella) for sociable dogs: kennels, daycare, shows — yearly booster | 12 weeks | 1 year after the primary course | every year |
| Rabiesnot routine in the UK — travel only | 12 weeks | 1 year after the primary course | every 3 years |
Ireland
| Vaccine | Primary course | First booster | Then |
|---|---|---|---|
| DHPthe dog's core shot: distemper, hepatitis (adenovirus), parvovirus — first booster at 1 year, then every 3 years | 8 weeks, 12 weeks | 1 year after the primary course | every 3 years |
| Leptospirosisleptospirosis — ENDEMIC in Ireland, yearly booster: immunity is shorter than the DHP core | 8 weeks, 12 weeks | 1 year after the primary course | every year |
| Kennel coughkennel cough — not routine, but required by most Irish boarding kennels | 12 weeks | 1 year after the primary course | every year |
| Rabiesrabies — for travel only: Ireland is rabies-free, no requirement for a resident animal | 12 weeks | 1 year after the primary course | every 3 years |
United States
| Vaccine | Primary course | First booster | Then |
|---|---|---|---|
| DAPPthe core dog combo: distemper, adenovirus, parainfluenza and parvovirus — booster at 1 year, then every 3 years | 8 weeks, 12 weeks, 16 weeks | 1 year after the primary course | every 3 years |
| Rabiesrequired by your state's law — age and schedule vary by state, ask your vet | 12 weeks | legal requirement, varies by local rules | legal requirement, varies by local rules |
| Leptospirosisbacteria spread by animal urine and standing water — yearly booster | 8 weeks, 12 weeks | 1 year after the primary course | every year |
| Bordetellakennel cough, for social dogs: boarding, daycare — yearly booster | 12 weeks | 1 year after the primary course | every year |
| Lymetick-borne bacteria, in endemic areas (Northeast, upper Midwest) — yearly booster | 12 weeks, 15 weeks | 1 year after the primary course | every year |
Canada
| Vaccine | Primary course | First booster | Then |
|---|---|---|---|
| DAPPthe core dog combo: distemper, hepatitis, parvovirus and parainfluenza — booster at 1 year, then every 3 years | 8 weeks, 12 weeks, 16 weeks | 1 year after the primary course | every 3 years |
| Rabiesrequired by law in several provinces — ask your vet | 12 weeks | legal requirement, varies by local rules | legal requirement, varies by local rules |
| Leptospirosisbacteria spread by rodent urine and standing water — depends on region and lifestyle; yearly booster | 12 weeks, 15 weeks | 1 year after the primary course | every year |
| Bordetellakennel cough for sociable dogs: boarding, daycare, shows — yearly booster | 12 weeks | 1 year after the primary course | every year |
| Lymetick-borne disease, established in Ontario and the Maritimes — yearly booster | 12 weeks, 15 weeks | 1 year after the primary course | every year |
Australia
| Vaccine | Primary course | First booster | Then |
|---|---|---|---|
| C3the core dog combo (C3): distemper, hepatitis and parvovirus — booster at 1 year, then every 3 years | 6 weeks, 12 weeks, 16 weeks | 1 year after the primary course | every 3 years |
| Kennel coughkennel cough (the “C5”), required by most boarding kennels — yearly booster | 12 weeks | 1 year after the primary course | every year |
| Leptospirosisbacteria spread by rodent urine — regional risk, mainly in Queensland; yearly booster | 12 weeks, 15 weeks | 1 year after the primary course | every year |
| Rabiesnot routine in Australia — export only | 12 weeks | 1 year after the primary course | every 3 years |
Why they differ
The gaps are not matters of opinion — they come from geography and law.
Rabies splits these countries in two. Britain and Ireland are rabies-free islands — Ireland has not seen an indigenous case since 1903 — and Australia is free of it too: the vaccine is not given routinely there, only for travel or export. Elsewhere it is the law, and the law is local: state by state in the United States, by provincial or municipal rule in Canada. That is why those tables show no suggested date: AnimaPulse flags the obligation without inventing a deadline it cannot know.
Leptospirosis. American guidance places it in the core group, and it is endemic in Ireland — the Veterinary Ireland Journal says so plainly, and a UCD study found pathogenic leptospires in healthy dogs. British and Irish practice give it every year, while the main combination moves to three-yearly: the appointment is annual, its contents are not. In Canada and Australia the risk is regional — Queensland especially — so it stays a lifestyle choice rather than a default. Either way, it is the one that lapses fastest — see below.
Names change, the vaccines do not. Australia counts its combinations: C3 is the core trio, C5 adds kennel cough. Britain and Ireland say DHP, North America says DAPP. The same diseases, one vocabulary per country — AnimaPulse keeps the name your own record uses.
Kennel cough (Bordetella, often with parainfluenza) is common in the UK for dogs that board, meet other dogs or go to daycare. In the US it sits alongside Lyme and other lifestyle vaccines chosen by risk.
What the letters mean
DHP stands for Distemper, Hepatitis and Parvovirus — the core combination. You will also meet DHPP, DAPP, DA2PP and DHPPi/L4: the same valences under different commercial names. The extra letters are parainfluenza and leptospirosis. AnimaPulse recognises these variants when you scan a label.
The puppy: why several injections
A puppy is protected for its first weeks by its mother's antibodies. Those same antibodies also neutralise the vaccine. Since nobody knows the exact date they fade — it varies from puppy to puppy — the injection is repeated so that at least one of them "takes".
Skipping the last one is not a saving. It is a bet on a date nobody knows.
Leptospirosis: the one people forget
A bacterial disease spread through rodent urine, usually via standing water, and transmissible to humans. Protection is short, so the booster is annual even when the rest of the combination moves to a slower rhythm. For a dog that swims, works or walks near water, it is the one not to let slip.
Remembering the dates
That is precisely what AnimaPulse does for you: enter (or scan) the vaccine, and the app works out the next due date and warns you seven days ahead, then again the day before.
