Why the schedule matters
Vaccinations protect against the most serious infectious diseases UK pets face — several of which can kill quickly and have no cure once symptoms appear. The schedule isn't arbitrary: doses are timed around when maternal antibodies fade and the immune system can mount its own response, and around the patterns of disease outbreak in the UK.
The protocols below reflect current BSAVA and BVA guidance and the licensing of UK-authorised vaccines. Your vet will adapt to your pet's individual risk — lifestyle, breed, environment, and exposure to other animals all matter, so always treat this as a starting point rather than a fixed prescription.
First vaccinations for puppies and kittens (typical)
Second dose to complete primary course
First booster after primary course
Subsequent core boosters (DHP / cat core)
Dogs
UK dog vaccinations are typically split into core (recommended for most dogs) and non-core (lifestyle-dependent).
Dog vaccinations — typical UK schedule
| Vaccine | Status | Schedule | Notes |
|---|---|---|---|
| Distemper, Hepatitis (Adenovirus), Parvovirus | Core | Two doses at 8–9 and 10–12 weeks; first annual booster at 12 months; thereafter at least every 3 years (depending on the licensed product). | Parvovirus in particular can kill puppies fast — worth completing the second dose on schedule. |
| Leptospirosis | Core (UK) | Same primary course as DHP; annual booster typical. | Annual is generally needed because immunity wanes faster than DHP. UK environmental risk is real (water, rats, livestock contact). |
| Parainfluenza | Core (UK) | Often combined with DHP as DHPPi. | Component of kennel cough complex. |
| Kennel cough (Bordetella) | Non-core | Single intranasal or injection annually if dog goes to kennels, training classes, or socialises with other dogs. | Most boarding kennels and many training classes ask for it. |
| Rabies | Travel only | Required for the Pet Travel Scheme; boosters per product datasheet. | 21-day waiting period after first dose generally applies before international travel. |
Why annual leptospirosis but three-yearly DHP?
DHP vaccines provide longer-lasting immunity — measured in years, with serological evidence supporting a 3-year interval after the first booster for many UK-licensed products. Leptospirosis vaccines, by contrast, generate shorter-lasting immunity (around 12 months), so an annual top-up is generally recommended. Your vet may use products that give DHP every 3 years and Lepto every year in the same appointment.
Cats
UK cat vaccinations follow a similar core / non-core split, with the breakdown reflecting both indoor/outdoor lifestyle and feline-specific disease risk.
Cat vaccinations — typical UK schedule
| Vaccine | Status | Schedule | Notes |
|---|---|---|---|
| Feline parvovirus (panleukopenia) | Core | Two doses at 8–9 and 11–12 weeks; first annual booster at 12 months; thereafter at least every 3 years (per licensed product). | Highly contagious and often fatal — kittens are particularly at risk. |
| Feline calicivirus | Core | Same primary course; annual booster typical. | Component of cat flu complex — chronic carriers are common. |
| Feline herpesvirus | Core | Same primary course; annual booster typical. | Other component of cat flu — cats can become lifelong latent carriers once infected. |
| Feline leukaemia virus | Non-core (often recommended for outdoor cats) | Two doses 3–4 weeks apart in primary course; annual or 3-yearly booster depending on product. | Spread by saliva (fights, shared bowls). Generally recommended for cats with outdoor access or in multi-cat households of unknown FeLV status. |
| Rabies | Travel only | Required for international travel; boosters per product datasheet. | Same 21-day rule as dogs. |
The vaccination gap is real for puppies and kittens
Pets are generally not considered fully protected until around two weeks after their second vaccination. Until then, it's wise to keep unvaccinated puppies off public ground and out of contact with unknown dogs. Kittens are typically kept indoors. Your vet will confirm the safe-to-go-out date for your pet.
Don't skip the 12-month booster
The first annual booster after the primary course is when long-term immunity is consolidated for most UK-licensed core vaccines. Skipping it often means starting the primary course again — two doses, all the cost, and a vulnerable window in between. Set a calendar reminder when you book the kitten or puppy course.
Talk lifestyle with your vet
Whether to add Bordetella for dogs or FeLV for cats depends on what your pet actually does. Daycare and kennels typically expect kennel cough. Outdoor or multi-cat households are often advised to add FeLV. There's usually little benefit to vaccinating against diseases your pet won't realistically encounter.
Update if you move
Leptospirosis risk varies geographically (waterways, livestock areas). FeLV risk depends on local cat population dynamics. A move — especially from urban to rural, or vice versa — is a sensible moment to review the schedule with your new vet.
Wellness plans usually save money
“If you're going to do core vaccinations, parasite control, and routine health checks anyway — most UK practices offer a wellness plan that bundles them into monthly payments. Done right, that often saves around 15–20 percent compared to paying per visit, and you don't have to remember the booster date because the practice does.”

Common questions
Book the next one in
The schedule is most useful when you treat it as a calendar event, not a one-off. Book the next booster at the end of every visit — your practice will text or email a reminder, and your pet stays protected without you needing to remember.
