Puppy Vaccinations: The UK Schedule, Boosters and When Your Puppy Can Go Out

Most UK puppies have their first vaccination at around 6 to 9 weeks old and a second dose 2 to 4 weeks later, which together make up the primary course. The core vaccines protect against parvovirus, distemper, infectious hepatitis and leptospirosis. Your puppy can usually go out in public about two weeks after the second jab, but the exact timings come from your vet, because they depend on the vaccine brand and your puppy's circumstances.

What vaccinations do puppies need in the UK?

Four core vaccines are recommended for all dogs in the UK: parvovirus, canine distemper, infectious canine hepatitis and leptospirosis. These are serious, often fatal illnesses, and some have no cure. Other vaccinations for dogs, such as kennel cough and rabies, depend on lifestyle and travel plans.

Whether you call them puppy jabs, puppy injections or puppy vaccines, they all refer to this same course and the boosters that follow.

Puppy vaccination schedule: when are the first vaccinations?

The course usually starts between 6 and 9 weeks of age, when your vet says your puppy is ready: PDSA puts the start at 6-8 weeks old and Blue Cross at 6 to 9 weeks. Two injections are normally given 2 to 4 weeks apart, and some puppies need a third. Your vet may move the first dose earlier or later depending on whether the mother was fully vaccinated.

Leptospirosis follows the same pattern: the second leptospirosis vaccination is given 2 to 4 weeks after the first.

Why schedules differ between vets

Puppies get antibodies from their mother, which protect them in the first few weeks of life but can also block a vaccine given too early. Vaccines work by exposing the body to harmless versions of bacteria and viruses so the immune system learns to fight them, and those maternal antibodies can neutralise the vaccine before it does its job. Because antibody levels vary from one puppy to the next, the international guidelines from WSAVA recommend repeat doses every 2 to 4 weeks with the final puppy dose at 16 weeks or older, then another dose at or after 26 weeks. Most vaccines licensed in Britain are authorised for a two-dose course instead. Both approaches are legitimate. Ask which schedule your practice uses and why, and follow their plan.

What happens at the vaccination appointment?

When you get your puppy vaccinated, expect a quick examination first to make sure they are well enough for the jab that day. The core vaccines are an injection, while kennel cough is given up the nose. Afterwards you get a record card showing what was given and when the next dose or booster is due.

Bring any paperwork from the breeder, a few treats to give, and a list of questions about worming, flea treatment and socialising.

How long after the second vaccination can a puppy go out?

Wait about two weeks after the second vaccination before you take your puppy to public places. PDSA says full protection begins 2 to 4 weeks after the final injection, so if a third dose was given, count from that one. Your vet will confirm the exact date for the brand they used.

Before then, there is still plenty to see:

• Carry them in public places rather than setting them on the ground.
• Use your own garden for play and toilet training, as long as it is fox-proof and no unvaccinated dogs have been in it recently.
• Avoid high-risk spots such as farms, freshwater, and anywhere with rats or mice until the course is complete, because leptospirosis spreads through urine in water and soil.

The rules for early outings, toilet trips and first walks are set out in our guide to when puppies can go outside.

When can a puppy meet other dogs?

Before vaccinations are finished, limit contact with other dogs to ones you know are fully vaccinated and healthy. Do not let them mix with unvaccinated dogs from outside your home, and avoid inviting unknown dogs round. Once the course is complete and the waiting period has passed, it is safe for your puppy to meet a wider range of dogs and join training classes, although each class sets its own rules.

This waiting period overlaps with weeks when young dogs are learning fast about the world, so do not keep them shut away. Calm meetings with vaccinated adult dogs, visitors to your home and carried trips out all count towards good puppy socialisation.

The diseases puppy vaccinations protect against

Canine parvovirus

Parvo spreads through infected vomit and faeces, and the virus can stay active in the environment for months to years. It causes severe vomiting and diarrhoea that quickly leads to weakness and dehydration, and without intensive treatment most infected dogs die. Finishing the course on time is the best protection, and our guide to parvo in puppies covers the signs to watch for.

Canine distemper

Distemper spreads mainly through saliva from an infected dog coughing and sneezing, and through urine. Early signs include fever, runny eyes and nose, poor appetite and coughing, and it can later cause seizures and weakness. There is no cure, so prevention is the only protection.

Infectious canine hepatitis

Canine adenovirus 1 infects the liver, while adenovirus 2 causes a respiratory illness similar to kennel cough. The virus spreads through saliva, urine, faeces and nasal discharge, and can survive for many months.

Leptospirosis

Leptospirosis is a bacterial infection spread in the urine of infected animals, which can contaminate water and soil. It can progress quickly to organ failure, and while antibiotics can treat it, long-term complications are common. BSAVA treats it as a core vaccine in Britain.

Kennel cough (optional)

Kennel cough vaccination is recommended for dogs that mix with lots of other dogs, and boarding kennels, day care, dog walkers and dog shows usually require it. It is given as a squirt up the nose rather than an injection. Sources differ on how long it lasts: PDSA describes it as a yearly vaccine while your dog is at risk, while Blue Cross says it protects for six months. Check what the product your practice uses covers.

How often do dogs need booster vaccinations to keep their immunity?

The primary course of vaccinations protects for about a year, after which your dog needs a first booster. After that, dogs need booster vaccinations throughout life, from young adult to elderly dog, and stopping them is leaving your dog at risk of infectious disease. Not every vaccine is due every year, though:

This is why adult dog vaccinations still mean a yearly appointment: it covers leptospirosis plus a health check, and the three-yearly core vaccines are added when they fall due. Many vets recommend an annual booster visit, partly because it is easier to remember.

Some owners ask about titre testing, a blood test that measures antibodies to help decide whether a core booster is needed. WSAVA supports it for parvovirus, distemper and hepatitis, but it does not reliably show protection against leptospirosis. Talk it through at your next appointment.

What if a booster is missed?

Tell your practice. It is never too late to vaccinate: dogs can be vaccinated at any age, and a dog whose status is unknown may need to restart their vaccination course with two injections given four weeks apart. Do not assume protection from vaccines given years ago.

How much are puppy vaccinations in the UK?

The Royal Kennel Club puts the first puppy vaccinations at roughly £40 to £70, with annual boosters at around £50. Prices vary between practices, so ask locally for a quote. Some vets offer the booster and a worming treatment together at the same appointment.

Are there side effects after the injection?

Side effects are rare and most dogs have none. Some puppies are a little quiet, off their food or slightly feverish for a day or two, and this usually passes within 24 to 48 hours. Serious reactions are extremely rare.

What vaccinations should a puppy have before leaving the breeder?

In England, no puppy under 8 weeks old may be sold or permanently separated from its mother by a licensed breeder. Because the first jab falls between 6 and 9 weeks, many puppies have their first vaccination before they go home, and the second dose is given by the new owner's vet. The breeder should hand over a vaccination card showing what was given, when, and when the next dose is due. Licensed breeders must also tell buyers the puppy's veterinary record.

If you're selling a litter of puppies, book the first vaccination and health check so they fall before the go-home date, and have a vaccination card ready for each new owner. Clear health paperwork is one of the first things careful buyers ask about, and our guide for breeders covers the rest of the preparation.

Buyer's checklist: vaccination paperwork

• A vaccination card or certificate from a named vet practice
• The date of the first vaccination and the vaccine name
• When the second dose is due
• Whether the mother was vaccinated
• Worming and flea treatment records

Respectable breeders can show proof of vaccination, and a licensed breeder in England must only show you a puppy together with its mother, something you can check for yourself when you buy direct from the breeder under Lucy's Law. If a seller cannot, or offers paperwork that looks vague, treat it as a warning sign and read our advice on buying a puppy safely before going further.

The first vet visit after bringing your puppy home

Book an appointment within the first week or so after bringing a puppy home. Take the breeder's vaccination card, so the course can continue with a compatible vaccine and the second jab can be booked. Ask about worming, flea treatment and when it will be safe to walk outside.

Keep the vaccination certificate safe. Boarding kennels, training classes and travel abroad may all ask to see it before accepting your dog.

Other health care in your puppy's first year

Vaccinations are one part of keeping a young puppy well. These are the other health topics new owners most often meet in the first months, and roughly when each one comes up:

When to see a vet

Contact your vet immediately if your puppy:

• has vomiting or diarrhoea, especially if they are not fully vaccinated
• seems very lethargic, collapses or has difficulty breathing after a vaccination
• develops facial swelling or hives after an injection

Call for advice if:

• mild tiredness or poor appetite after a jab lasts longer than 48 hours
• you do not know whether your puppy has been vaccinated, or you have lost the card
• your dog has a cough, a runny nose or sore eyes
• a booster has been missed

Frequently asked questions

When do puppies have their vaccinations?

The first vaccination is usually given between 6 and 9 weeks old, with a second dose 2 to 4 weeks later. Some vets add a third dose at 16 weeks or older.

Can my puppy go in the garden before their vaccinations?

Yes, if your garden is fox-proof and no unvaccinated dogs have visited it recently. It is a good place for toilet training and short play sessions.

Can my puppy meet other dogs after their first vaccination?

Only dogs you know are fully vaccinated and healthy, such as a friend's adult dog in a private garden. Wait until the course is complete before meeting dogs of unknown vaccination status.

Does my puppy need a rabies vaccination?

Not to live in the UK. You need a rabies vaccination to take your dog abroad, and the dog must be at least 12 weeks old and microchipped first.

Is the kennel cough vaccine included in the puppy jabs?

Not usually. Kennel cough is a separate vaccine given as a nasal spray, and is worth discussing if your dog is likely to board, go to day care or mix with lots of dogs.

Do I have to vaccinate my puppy?

Vaccinating your dog is a decision you make with your vet, who should agree a programme suited to your dog. Kennels, training classes and travel abroad may all require proof of vaccination.
