UK puppies typically start core vaccinations at six to eight weeks, with a second dose two to four weeks later, followed by annual and three-yearly boosters into adulthood. Vaccinations aren’t legally required in the UK, but they protect against serious, often fatal diseases and are required by most kennels, dog walkers and for international travel.
The Puppy Vaccination Timeline
| Age | What Happens |
|---|---|
| 6 to 8 weeks | First dose of core vaccines: distemper, parvovirus, adenovirus and leptospirosis |
| 10 to 12 weeks | Second dose of core vaccines, completing the primary course |
| 12 weeks+ | Non-core vaccines available if needed, such as kennel cough or Lyme disease, depending on lifestyle |
| 2 weeks after final dose | Full protection reached, generally safe to walk in public places |
| 6 to 12 months | First booster vaccination |
Some vets recommend a third dose for certain breeds, such as Rottweilers and Doberman Pinschers, for maximum protection against parvovirus. Always follow your own vet’s specific schedule, since timing can vary slightly by practice and vaccine brand.
Core Vaccines Explained
- Distemper — a serious viral disease affecting multiple organs and the nervous system
- Parvovirus — causes severe, often fatal digestive illness, particularly dangerous in puppies
- Infectious hepatitis (adenovirus) — affects the liver and other organs
- Leptospirosis — a bacterial infection spread through contaminated water, common in damp UK environments, and one of the few core diseases that can also affect humans
Non-Core Vaccines: Do You Need Them?
Non-core vaccines are recommended based on lifestyle rather than given to every dog automatically.
- Kennel cough — recommended for dogs attending kennels, daycare or group training classes, and often required by these facilities
- Lyme disease — worth considering for dogs walked frequently in rural or wooded areas with high tick exposure
- Rabies — required for international travel under a pet passport scheme, not for general UK life
Adult Booster Schedule
Once your dog completes their puppy course and first booster, most UK vets follow this pattern:
- Leptospirosis — annual booster, since immunity wanes faster than with other core vaccines
- Distemper, hepatitis and parvovirus — boosters typically every three years
- Kennel cough — annual, if your dog’s lifestyle requires ongoing cover
Most vet practices send reminders, but keeping your own record, or your dog’s vaccination card, up to date is worth doing in case you switch practices.
What to Expect at a Vaccination Appointment
Your vet will typically carry out a general health check alongside the vaccination, since this is also a useful opportunity to catch other issues early. Mild, short-term side effects such as tiredness or slight soreness at the injection site are common and normally resolve within a day or two. Contact your vet if you notice swelling, vomiting, or unusual lethargy lasting more than 24 hours. This is also a good time to bring up any concerns about parasite prevention, since flea and tick treatment is often discussed alongside vaccination visits.
Socialising Safely Before Vaccination Is Complete
Waiting until full protection to begin socialisation can mean missing a critical developmental window. Many vets now recommend carrying puppies in public, or arranging safe, controlled interactions with healthy, fully vaccinated dogs, so socialisation can begin before the final dose. Speak to your vet about what’s appropriate for your puppy. Our positive dog training tips guide covers how to build good habits during this early stage.
If You’ve Missed a Booster
A short delay usually isn’t a serious problem, but a significantly overdue booster may mean your vet recommends restarting the primary course rather than a single top-up dose. Contact your vet as soon as you realise a booster is overdue rather than waiting for the next reminder.
Frequently Asked Questions
Are dog vaccinations legally required in the UK?
No, routine vaccinations are not a legal requirement, but they are strongly recommended, and many kennels, daycare centres and dog walkers will not accept an unvaccinated dog.
How much does dog vaccination cost in the UK?
A puppy primary course typically costs around £100 to £150, with adult annual boosters ranging from roughly £50 to £85, though prices vary by practice and location.
Can my puppy go for walks before finishing their vaccinations?
Public areas are generally best avoided until your vet confirms full protection, roughly two weeks after the final dose, though safe socialisation options exist before this point.
What happens if I miss my dog’s booster date?
Contact your vet as soon as possible. A short delay is often fine, but a longer gap may mean the primary vaccination course needs to be restarted.
Key Takeaways
- Puppies need two core vaccine doses, typically at 6 to 8 weeks and 10 to 12 weeks
- Leptospirosis needs an annual booster; other core vaccines are usually boosted every three years
- Non-core vaccines like kennel cough depend on your dog’s lifestyle
- Contact your vet promptly if a booster is overdue rather than waiting
