Dog Vaccination Schedule UK: Core Vaccines, Timing, and Boosters Explained

Getting your dog's vaccinations right from the start is one of the most important things you can do for their long-term health. But the schedule can be confusing - especially when different vets follow slightly different protocols and the paperwork uses abbreviations nobody explains. According to the PDSA PAW Mini Report 2025, 80% of UK dogs receive regular booster vaccinations - but that still leaves around 2 million dogs without current vaccine protection, with 11% of non-vaccinating owners citing cost as the reason.

Here's a clear, plain-English guide to how it all works in the UK.

Core vs Non-Core Vaccines

UK vets divide canine vaccines into two categories:

Core vaccines - recommended for every dog, regardless of lifestyle:

• Distemper
• Parvovirus
• Hepatitis (Adenovirus)
• Leptospirosis

Non-core vaccines - recommended based on individual risk:

• Kennel cough (Bordetella bronchiseptica + parainfluenza)
• Rabies (required only for dogs travelling outside the UK)

The Puppy Primary Course

Puppies need a primary course of vaccinations because their maternal antibodies (passed through their mother's milk) gradually wane, leaving a window of vulnerability. The timing is designed to start protecting puppies as that window opens.

| Age | Vaccines | | ----------- | ------------------------------------------------------------- | | 6–8 weeks | Distemper, Parvovirus, Hepatitis (some vets start this early) | | 10–12 weeks | Distemper, Parvovirus, Hepatitis, Leptospirosis | | 14–16 weeks | Second Leptospirosis dose |

Most vets recommend waiting until 1–2 weeks after the final puppy jab before letting your puppy socialise freely on public ground. This is a judgement call - the socialisation window matters enormously too - so discuss the specific timing with your vet.

Kennel cough is typically given as a separate nasal spray, and can be given from around 3 weeks of age.

Adult Booster Schedule

After the primary course, your dog needs annual boosters - but not for everything every year.

| Vaccine | Booster Frequency | | ------------- | --------------------- | | Leptospirosis | Annually | | Distemper | Every 3 years | | Parvovirus | Every 3 years | | Hepatitis | Every 3 years | | Kennel Cough | Annually (if at risk) |

Your vet will typically combine these into a single appointment that covers whatever's due. The annual visit is also a good opportunity for a full health check, which is why vets recommend keeping to the schedule even in years when boosters are minimal.

Titre Testing: An Alternative to Automatic Boosters

Some owners prefer titre testing - a blood test that measures whether your dog still has sufficient antibodies to be protected - rather than automatically giving every booster. This is particularly relevant for the 3-year vaccines (distemper, parvovirus, hepatitis).

Titre testing is an accepted approach and many vets support it. Leptospirosis is the exception - immunity wanes quickly and titres aren't as reliable a predictor, so the annual lepto jab is generally recommended regardless.

Kennel Cough: What You Need to Know

See our kennel cough condition guide for what to monitor if your dog develops symptoms after a vaccination lapse or kennel stay.

Kennel cough isn't a single disease - it's a complex of respiratory pathogens. The vaccine covers the most significant ones (Bordetella bronchiseptica and parainfluenza virus), but it doesn't prevent all causes of kennel cough entirely. Think of it like the flu jab - highly effective at reducing severity and spread, but not an absolute guarantee. The BSAVA (British Small Animal Veterinary Association) has highlighted a concerning decline in UK pet vaccination uptake in recent years, warning that millions of pets are at risk of deadly diseases including parvovirus and leptospirosis as herd immunity falls in some populations.

Most kennels, doggy daycares, and groomers require proof of kennel cough vaccination within the past 6–12 months.

How to Prepare for Your Dog's Vaccination Appointment

1. Bring your dog's vaccination record/passport if you have it
2. Make note of any changes in behaviour, appetite, or health since the last visit
3. Ask your vet about anything specific to your dog's lifestyle (travel, socialisation, outdoor access)
4. Ask whether titre testing is appropriate for the current year

Tracking Vaccinations in Pup Notes

Keeping track of which booster is due when is exactly the kind of thing that slips through the cracks. In Pup Notes, you can log each vaccination, store the date and product name, and get a reminder when the next one is approaching - so you're never caught out by a kennel's requirements at short notice.

Frequently Asked Questions

When should puppies get their first vaccination in the UK? Typically around 6–8 weeks for the first dose, with the second at 10–12 weeks and a third (for leptospirosis) at 14–16 weeks. Your specific timing may vary by vet and the products used.

How long after the last puppy jab can my dog go outside? Most vets recommend waiting 1–2 weeks after the final puppy vaccination before allowing free contact with public ground or unknown dogs. However, this shouldn't delay socialisation - supervised contact with vaccinated, healthy dogs is fine earlier.

Can I miss a booster and restart? If your dog has missed a booster by more than a year, your vet may recommend starting a partial or full course again depending on which vaccines are overdue. Don't panic - just book an appointment.

Is the kennel cough vaccine mandatory? Not by law, but most kennels, doggy daycares, and many groomers require it. If you use any of these services, it's effectively mandatory in practice.
