Vaccinations are one of the most important things you will do for your puppy’s health. They protect against diseases that were once common killers of dogs in the UK — and that can still be fatal if contracted by an unvaccinated animal. This guide covers the current UK vaccination schedule for 2026, including what each vaccine protects against, when your puppy can safely go outside, and what boosters are needed long-term.
Core Vaccination Schedule (2026)
| Age | Vaccine | Protects Against |
|---|---|---|
| 6–8 weeks | DHP (1st dose) + Leptospirosis (1st dose) | Distemper, Hepatitis, Parvovirus + Leptospirosis |
| 10–12 weeks | DHP (2nd dose) + Leptospirosis (2nd dose) | Same — completing the primary course |
| 12–16 weeks (some protocols) | DHP (3rd dose — if required by vaccine brand) | Especially for breeds at higher parvovirus risk |
What the vaccines protect against
- Distemper: Attacks the nervous system, respiratory system and gut. Often fatal. Rare in the UK now because of vaccination
- Hepatitis (Adenovirus): Attacks the liver and kidneys. Can be fatal within hours in severe cases
- Parvovirus: Devastating gut disease causing severe bloody diarrhoea and dehydration. Survives in the environment for months. Still kills unvaccinated puppies in the UK every year
- Leptospirosis: Bacterial infection spread by rat urine and contaminated water. Attacks kidneys and liver. Can be transmitted to humans (zoonotic). Annual booster essential — immunity wanes faster than DHP
When Can My Puppy Go Outside?
Your puppy is safe to walk on public ground 1–2 weeks after their second vaccination (typically around 12–14 weeks of age). This allows their immune system to develop full protection.
Before this point:
- ✅ Your own secure garden (if no unvaccinated dog/fox access)
- ✅ Carrying your puppy in public (socialisation without ground contact)
- ✅ Friends’ gardens with fully vaccinated dogs
- ❌ No pavements, parks, pet shops, or any ground where unknown dogs walk
Non-Core Vaccines
Kennel Cough (Bordetella + Parainfluenza)
A nasal spray vaccine protecting against the most common causes of infectious tracheobronchitis. Recommended if your puppy will attend:
- Daycare, boarding kennels, dog shows, training classes, busy parks
- Given as a single nasal dose; typically repeated annually
- Not a legal requirement but often required by kennels and daycare facilities
Rabies
Rabies does not exist in the UK. Vaccination is only required if you plan to travel abroad with your dog. Can be given from 12 weeks. Required for the Animal Health Certificate (AHC) for EU travel.
Booster Schedule
| Vaccine | First Booster | Ongoing |
|---|---|---|
| DHP | 12 months after primary course | Every 3 years |
| Leptospirosis | 12 months after primary course | Every year (immunity wanes) |
| Kennel Cough | Annually | Annually (or every 6 months for high-risk dogs) |
FAQs
Can I skip the Leptospirosis vaccine?
Some owners consider it because Lepto vaccines can occasionally cause mild side effects (lethargy, mild swelling at injection site). However, Leptospirosis is present throughout the UK — anywhere rats have been — and is both potentially fatal to dogs and transmissible to humans. The BSAVA and major UK vet bodies recommend vaccination. If you have concerns, discuss with your vet, but the risk of the disease far outweighs the risk of the vaccine.
