Puppy & Kitten Vaccination Schedule (UK 2025)

Bringing home a new puppy or kitten is exciting—and a little overwhelming. Vaccinations are one of the most important early steps you can take to protect your pet against serious infectious diseases. Here’s a simple, UK‑specific guide to what’s due, when, and why it matters.

Why vaccinate early?

• Puppies and kittens are vulnerable as maternal antibodies fade around 6–8 weeks.

• Vaccines “teach” the immune system to respond before real exposure to disease.

• Early protection supports safe socialisation and healthier development.

Puppy schedule (UK)

• First course: typically starts at 6–8 weeks.

• Second dose: 2–4 weeks later.

• Sometimes a third primary dose is advised (vet- and product-dependent).

• Boosters: leptospirosis annually; DHP (distemper, parvovirus, hepatitis) typically every 3 years.

• Optional based on risk/travel: kennel cough (yearly), rabies (for travel).

Reference: PDSA guidance outlines a typical UK schedule, including annual leptospirosis boosters and 3‑yearly DHP boosters for adults. See: PDSA – Dog Vaccines.

Kitten schedule (UK)

• First course: often starts around 8–9 weeks.

• Second dose: typically 3–4 weeks later (often at 12 weeks).

• Core vaccines commonly include feline panleukopenia (parvovirus), calicivirus, herpesvirus; FeLV is recommended for most cats that go outdoors or live in multi‑cat homes.

• Boosters: usually 12 months after the primary course, then per vaccine guidelines (commonly annual or triennial depending on pathogen and product).

What about going outside?

• Puppies: safe outings generally 1–2 weeks after the primary course is complete (confirm with your vet).

• Kittens: keep indoors until fully protected; discuss timing if early controlled outdoor exposure is planned.

Side effects and safety

• Most reactions are mild (sleepiness, small tender lump) and resolve in 24–48 hours.

• Serious reactions are rare—contact us if you’re concerned.
