Dog Vaccinations UK: Core Vaccines, Boosters and Costs

Adult dog vaccinations in the UK protect against diseases that still circulate in the dog population and can be fatal without prior immunity. After the puppy primary course, your dog needs annual leptospirosis boosters and three-yearly boosters for distemper, hepatitis and parvovirus, unless titre testing confirms existing immunity. This guide covers the full adult schedule, costs and what to discuss with your vet.

Why Ongoing Vaccination Matters

Vaccination is not a one-time event. The immunity provided by the puppy primary course fades over time at different rates for different diseases. Leptospirosis immunity, in particular, is relatively short-lived and requires annual boosting. Allowing a significant gap in your dog's vaccination record can require restarting the primary course rather than simply picking up where you left off.

The British Veterinary Association (BVA) supports vaccination as the most cost-effective preventative health measure available to dog owners and recommends following your vet's guidance on booster schedules, which may vary slightly based on the vaccine products used at your practice.

Core UK Adult Dog Vaccines

Distemper (CDV) A severe systemic disease affecting the respiratory system and central nervous system. Often fatal. Immunity from vaccination typically lasts 3 years for adult dogs after the puppy primary course. Three-yearly boosters are standard.

Infectious Canine Hepatitis (Adenovirus) Attacks the liver and kidneys. Can cause acute liver failure. Three-yearly boosters standard.

Parvovirus (CPV) One of the most serious dog diseases, causing severe gastrointestinal illness and rapid death in unvaccinated dogs. Extremely hardy in the environment: can survive in soil for a year or more. Three-yearly boosters standard; some vets recommend annual boosting in high-risk areas.

Leptospirosis A bacterial infection spread through rat urine and contaminated standing water, rivers and canals. Affects the kidneys and liver; transmissible to humans (Weil's disease). Immunity from vaccination is shorter-lived than for viral diseases, requiring annual boosting. The L4 vaccine, which covers four serovars, is now standard in the UK and supersedes the older L2 vaccine.

Non-Core Vaccines

Kennel Cough (Bordetella bronchiseptica / Parainfluenza) Not a core vaccine but strongly recommended for any dog that uses boarding kennels, daycare, dog shows or dog parks. Given as an intranasal spray; takes effect within 3 to 5 days. Annual or bi-annual booster. Cost: £25 to £40. Required by most boarding kennels as a condition of entry.

Rabies Only required for dogs travelling outside the UK under the pet travel scheme. Must be given at least 21 days before travel (for a first-time vaccination). Requires an up-to-date pet passport or animal health certificate. Cost: £40 to £60. Not part of the standard UK schedule.

Herpesvirus (CHV) Relevant to breeding bitches only. Protects litters from neonatal herpesvirus. Not required for pet dogs.

The UK Adult Booster Schedule

Vaccine	Frequency
Distemper, hepatitis, parvovirus	Every 3 years
Leptospirosis (L4)	Annually
Kennel cough	Annually or bi-annually
Rabies	As required for travel

Your vet will typically combine leptospirosis with the three-yearly boosters in a single appointment every three years. In the years between, only leptospirosis requires boosting. Your practice should send an annual reminder.

UK Vaccination Costs (2025 to 2026)

Item	Typical UK cost
Annual booster (lepto only)	£40 to £70
Three-yearly booster (combined)	£55 to £90
Kennel cough	£25 to £40
Titre test (3 core diseases)	£80 to £150
Rabies	£40 to £60

Costs are higher in London and the South East. Many practices offer health plans at £15 to £30 per month that include annual boosters, flea and worm treatment and a discount on other services. These are worth comparing against paying individually.

Titre Testing: An Alternative to Automatic Boosters

Titre testing measures existing antibody levels in your dog's blood for specific diseases. A dog with adequate titre levels for distemper, hepatitis and parvovirus does not need a booster for those diseases. This is particularly useful for dogs with a history of vaccine reactions, or owners who prefer to avoid vaccinating when immunity is demonstrably present.

The BVA supports titre testing as a valid alternative to automatic three-yearly boosters for the core viral vaccines. However, titre testing is not a reliable measure of leptospirosis immunity, and annual leptospirosis boosters should continue regardless.

Cost of titre testing varies by the number of diseases tested: typically £80 to £150 for the three core vaccines.

What Happens If You Miss a Booster?

Missing a booster by a few weeks is rarely a problem. Your vet can assess whether the lapsed gap requires a restart:

• Leptospirosis: a gap of more than 12 to 15 months typically requires restarting the two-dose primary course, not just a single top-up
• Core viral vaccines (DHP): a gap of several years may require re-priming with two doses; titre testing can help determine whether boosting is necessary at all

If your dog needs to go into boarding and their vaccination record has lapsed, most kennels will not accept them until vaccination status is confirmed. Contact your vet as early as possible before any planned boarding.

Reactions to Vaccination

Mild reactions are common and expected: a small lump at the injection site, mild lethargy for 24 to 48 hours and reduced appetite. These resolve without treatment.

Serious reactions (anaphylaxis) are rare but can occur. Signs include facial swelling, hives, vomiting, collapse or difficulty breathing within minutes to hours of vaccination. If you observe any of these signs, contact your vet or an emergency practice immediately.

Most practices ask you to wait 15 to 20 minutes after vaccination so they can respond if a reaction occurs.

Frequently Asked Questions

Does my dog legally have to be vaccinated in the UK?

No. There is no legal requirement to vaccinate a dog in the UK. However, most boarding kennels, daycare facilities and dog shows require up-to-date vaccination records as a condition of entry. Vaccination is strongly recommended by the BVA and PDSA as the most effective preventative health measure available.

How do I know when my dog's boosters are due?

Your vet practice should send an annual reminder. Your dog's vaccination record card lists what was given and when. If you are unsure, your vet can check the records and advise whether boosters are due or whether titre testing is appropriate.

My dog had a reaction to a previous vaccine. Should I still vaccinate?

Discuss this with your vet before the next booster. Options include pre-medicating with antihistamine, splitting vaccines given on the same day, titre testing to assess whether boosting is necessary, or selecting a different vaccine product. Vaccine reactions should always be recorded on the dog's notes.

Can I get my dog vaccinated at a vet nurse clinic rather than a full vet appointment?

Yes. Many UK practices offer vet nurse vaccination clinics at a lower cost than a full vet appointment. The vet nurse will conduct a brief pre-vaccination health check. If they identify any concerns, they will refer to a vet before proceeding.

Is the L4 leptospirosis vaccine the same as the old L2?

No. The L4 vaccine covers four serovars (strains) of leptospirosis compared to the two covered by the older L2 vaccine. L4 has been the standard in UK practices since around 2014. If your dog was previously vaccinated with L2 and has not received L4, discuss the switch with your vet as a different initial protocol may be recommended.

What is the kennel cough vaccine and does my dog need it?

Kennel cough is a highly contagious respiratory infection common in dogs that mix with other dogs. The intranasal vaccine provides protection against the main causative agents within 3 to 5 days. It is not a core vaccine but is recommended for any dog using boarding, daycare, shows or dog parks, and required by most boarding kennels.
