Core vs non-core vaccines — what's the difference?
UK vets divide dog vaccines into two categories. Understanding the distinction helps you have a more informed conversation with your vet — and avoid paying for things your dog doesn't need, or skipping things they do.
Core vaccines
Recommended for every dog in the UK, regardless of lifestyle. These protect against diseases that are highly contagious, potentially fatal, or present significant public health risk.
Non-core vaccines
Recommended based on your dog's individual lifestyle and risk exposure. If your dog goes to kennels, daycare, group walks or dog parks, these become strongly recommended.
Practical rule: If your dog will ever go to kennels, doggy daycare, group dog walks, or mix with unfamiliar dogs in parks — get kennel cough too. The core four are non-negotiable for all dogs.
The complete UK dog vaccination table (2026)
Here's a clear breakdown of every vaccine your UK dog might need — what it is, when it's given, and how often it needs repeating.
Highly contagious viral disease. Often fatal. No treatment — prevention only.
Bloody diarrhoea, rapid dehydration, death. Young puppies most at risk. Survives in environment for years.
Infectious canine hepatitis. Liver failure, eye damage ('blue eye'). Uncommon since vaccination — but present.
Bacterial disease from rat urine/contaminated water. Kidney and liver failure. Can pass to humans (Weil's disease). UK parks and rivers carry real risk.
Highly contagious respiratory disease. Not fatal in healthy adults but miserable and causes up to 6 weeks of coughing. Required for kennels, daycare and group dog walks.
Required for Pet Passport / APHA travel compliance. UK is rabies-free. Not given routinely.
Puppy vaccination schedule, week by week
The exact timing varies slightly between vet practices and depends on when your puppy was born and what the breeder has already given. This is the typical UK schedule for a puppy joining you at 8 weeks:
When can your puppy go outside?
This is the most common question new puppy owners have — and the answer is slightly more nuanced than the old "wait until 2 weeks after second jab" advice.
Before first vaccination (up to 8 weeks)
Puppy relies on maternal antibodies. Limit outdoor exposure. No public ground contact. Can visit vaccinated dogs in their private gardens.
After first vaccination (8–10 weeks)
Not yet fully protected. You can carry your puppy in public to continue socialisation — they need to see the world even if their paws can't touch it yet. Visit friends' vaccinated dogs indoors.
1–2 weeks after second vaccination (typically 12–14 weeks)
Full outdoor freedom. Parks, pavements, dog training classes, meeting other dogs. This is the moment you've been waiting for.
Important: the socialisation window
The critical window for puppy socialisation closes at around 16 weeks. Don't sacrifice all socialisation to avoid unvaccinated-ground risk. Carry them, visit vaccinated homes, use puppy classes in clean indoor spaces. A fearful adult dog is harder to manage than a theoretical parvovirus exposure.
Puppy just cleared for outdoor walks?
Puppy walkers follow the 5-minute rule (per month of age) and know exactly how to structure early walks for development, not just exercise. Find a verified, insured puppy walker near you — GPS-tracked walks, photo updates after every session.

A common misconception: not everything needs boosting every year. The schedule is staggered.
| Vaccine | 12-month booster | Ongoing frequency |
|---|---|---|
| Distemper (D) | ✓ Yes (first booster) | Every 3 years thereafter |
| Parvovirus (P) | ✓ Yes (first booster) | Every 3 years thereafter |
| Hepatitis (H) | ✓ Yes (first booster) | Every 3 years thereafter |
| Leptospirosis (L4) | ✓ Yes — essential | Every year (immunity wanes quickly) |
| Kennel cough (KC) | ✓ If lifestyle warrants | Every year |
⚠️ If you miss a booster
Most practices allow a grace period of up to 15 months between vaccines before the immunity is considered lapsed. If you're more overdue than that, your dog may need to restart the primary course (two injections, 2–4 weeks apart). Always check with your vet — don't assume a missed year means starting from scratch.
Kennel cough — is it worth it?
Short answer: if your dog mixes with other dogs, yes. Kennel cough is extraordinarily contagious — it spreads through the air, on surfaces, and by sniffing. A dog at a busy park can pick it up without direct contact.
The disease itself isn't usually fatal in healthy adult dogs — but it causes a horrible dry honking cough for 2–6 weeks, and puppies, elderly dogs, and immunocompromised dogs can develop pneumonia from it.
When to get it
- ✓Kennels or boarding (most require it)
- ✓Doggy daycare
- ✓Group dog walks
- ✓Dog training classes
- ✓Regular dog parks and off-lead areas
- ✓Dog shows or events
How it's given
The leptospirosis (L4) debate — what you actually need to know
In 2017, a significant number of adverse reaction reports were filed with the Veterinary Medicines Directorate (VMD) following the introduction of the broader L4 vaccine (covering 4 leptospira strains, up from the previous L2's 2 strains). This created genuine concern among some dog owners and vets.
What the VMD concluded
After review, the VMD concluded that the benefits of L4 outweigh the risks, and it remains licensed and recommended. The adverse reaction rate was found to be low — most reported reactions were mild (lethargy, soreness at injection site) and transient. Serious adverse events were rare.
Is leptospirosis actually a risk?
Yes — and it's growing. Leptospirosis is spread through rat urine and contaminated water (rivers, canals, puddles, flooding). With flooding events increasing in the UK, water exposure risk is rising. It can cause fatal kidney and liver failure — and it can pass to humans (Weil's disease). Any dog that swims, walks near water, or lives near farmland is at real risk.
The L2 vs L4 question
The older L2 vaccine (Nobivac Lepto 2) covers 2 leptospira strains and has a longer safety track record. Some practices have reverted to offering this as an alternative for owners with concerns. L4 provides broader protection — particularly relevant in areas where additional strains circulate. Discuss with your vet which is more appropriate for your dog's lifestyle and your local area.
Bottom line: If you have concerns about L4, raise them with your vet — don't just skip leptospirosis vaccination entirely. The disease it prevents is genuinely serious. The question is L2 vs L4, not "vaccinate vs don't vaccinate."
Vaccination costs: what to expect at the vet (2026)
Vet fees vary significantly by region and practice type — a London veterinary hospital charges substantially more than a rural mixed practice in the North West. These are realistic UK-wide ranges:
| Item | Low | High |
|---|---|---|
| Primary puppy course (2 injections) | £50 | £120 |
| Kennel cough vaccination | £25 | £50 |
| Annual booster (Lepto + check-up) | £40 | £80 |
| 3-year booster (DHP + Lepto) | £55 | £120 |
| Titre test (check immunity level) | £60 | £150 |
| Consultation fee (if charged separately) | £0 | £40 |

Frequently asked questions
What vaccinations do dogs need in the UK?
UK dogs need four core vaccinations: distemper, parvovirus, adenovirus/hepatitis, and leptospirosis. These are non-negotiable for all dogs. Kennel cough is non-core but strongly recommended if your dog will attend kennels, daycare, group walks or dog parks.
How much do dog vaccinations cost in the UK?
The primary puppy course (two injections 2–4 weeks apart) typically costs £50–120. Annual boosters cost £40–80. Kennel cough adds £25–50. Costs vary by region — London and the South East are typically 20–40% higher.
When can a puppy go outside after vaccinations in the UK?
Most vets advise 1–2 weeks after the second vaccination (typically at 10–12 weeks), giving full outdoor freedom from around 12–14 weeks. Before full vaccination, carry your puppy in public for socialisation — just keep them off ground where unvaccinated dogs may have been.
What is the L4 leptospirosis vaccine and is it safe?
L4 covers 4 leptospira strains vs the older L2 (2 strains). There was controversy in 2017 about adverse reactions, but the VMD concluded benefits outweigh risks and it remains recommended. If you have concerns, discuss with your vet — the older L2 is available as an alternative at some practices.
How often do adult dogs need vaccinations in the UK?
Leptospirosis requires an annual booster. Distemper, parvovirus and hepatitis are typically boosted at 12 months then every 3 years. Kennel cough (if given) is annual. Your vet should send reminders.
Does my dog need vaccinations to go to daycare or kennels?
Almost universally yes. Reputable kennels, daycare providers and group dog walk services require up-to-date vaccinations including kennel cough. They'll ask to see your dog's vaccination record (the red book from your vet).
