A puppy needs a short series of core vaccinations, not a single injection. The World Small Animal Veterinary Association (WSAVA) vaccination guidelines recommend starting the core vaccines no earlier than six weeks of age and repeating them every three to four weeks until the puppy is at least 16 weeks old, with a further booster at about six months. After that, core vaccines are given no more often than every three years. Rabies follows its own schedule, and in South Africa it is not optional: it is a legal requirement for every dog and cat.
The dog vaccination schedule at a glance
This is the shape of a typical puppy vaccination schedule based on the WSAVA guidance. Your vet’s exact protocol depends on the products they use and local disease risk, so follow their timings where they differ.
- 6 to 8 weeks: first core vaccine (distemper, parvovirus and adenovirus).
- Every 3 to 4 weeks after that: repeat core doses until the puppy is 16 weeks or older.
- From about 12 weeks: first rabies vaccination.
- About 6 months: core booster, recommended by WSAVA instead of waiting until 12 to 16 months.
- 1 year: rabies revaccination, either at one year of age or one year after the first dose.
- Adult dogs: core boosters no more often than every three years; rabies every one or three years depending on the vaccine and the law; leptospirosis and kennel cough annually where your vet recommends them.
How many vaccinations does a puppy need?
Puppy vaccinations usually come to three or four core doses, depending on when the series starts. A puppy first vaccinated at six weeks and boosted every three to four weeks will have about four doses by 16 weeks; one that starts at eight weeks will have three. The repetition is deliberate. Puppies receive antibodies from their mother, and those maternal antibodies protect them early on but also block the vaccine. Nobody can tell for an individual puppy exactly when they fade, so the doses are repeated until well past the point where they should have gone. The six-month booster exists for the same reason: WSAVA notes that it closes the gap for any puppy that did not respond to the earlier doses.
Core vaccines every dog needs
- Canine parvovirus: severe vomiting and diarrhoea, most dangerous in puppies. The virus is unusually tough. It survives indoors for months and outdoors in moist environments for years, which is why an unvaccinated puppy should not walk where unknown dogs toilet.
- Canine distemper: a viral disease affecting the respiratory, digestive and nervous systems, often fatal.
- Canine adenovirus: the vaccine protects against infectious canine hepatitis.
- Rabies: fatal and transmissible to people. Compulsory in South Africa, as set out below.
The first three are normally given together in one combination injection. Products sold as a “5-in-1” add further components, and the mix varies by brand, so ask your vet which diseases your dog’s vaccine actually covers.
Rabies vaccination is the law in South Africa
Rabies is a controlled disease under the Animal Diseases Act (Act 35 of 1984), and, as the NSPCA points out, owners of dogs and cats are legally required to have them vaccinated. The consequences of skipping it are serious. National animal health guidance is that an unvaccinated animal which has been in contact with a rabid animal must be euthanised. A correctly vaccinated dog, by contrast, is protected. Keep the certificate: proof of up-to-date vaccination is central to the official risk assessment after a bite.
Dog rabies in South Africa is concentrated in the eastern provinces, chiefly KwaZulu-Natal, the Eastern Cape and Limpopo, but the Western Cape is not exempt. In July 2024 rabies was confirmed in 17 Cape fur seals along the coast between Cape Town and Plettenberg Bay, which matters to anyone who walks a dog on the beach. State veterinary clinics often offer rabies vaccination free of charge, so cost is not a reason to fall behind.
Non-core vaccines: kennel cough and leptospirosis
Non-core vaccines are given according to your dog’s lifestyle and local risk.
- Kennel cough (Bordetella bronchiseptica and canine parainfluenza): worth considering for dogs that board, go to daycare or attend classes, and many kennels ask for it. It is usually boosted annually.
- Leptospirosis: spread through the urine of infected animals and contaminated water, and transmissible to people. WSAVA treats it as core wherever it is endemic: two initial doses two to four weeks apart from about eight weeks, then annually. Ask your vet whether it is recommended where you live.
Socialising a puppy before the vaccinations are finished
This is where vaccination and behaviour meet, and getting the balance right shapes the adult dog. WSAVA states that careful socialisation can begin before the vaccination series is complete. The American Veterinary Society of Animal Behavior goes further: its position is that puppies can start socialisation classes from seven to eight weeks, provided they have had at least one set of vaccines seven days before the first class and a first deworming. The reason is timing. The puppy socialisation window runs from roughly 3 to 14 weeks, so waiting until 16 weeks means missing most of it.
Practical ways to do both safely:
- Carry your puppy to see traffic, shops and people rather than putting them down on public ground.
- Arrange meetings with healthy, fully vaccinated adult dogs in a private garden.
- Use your own garden as the toilet area while potty training your puppy, rather than shared verges.
- Choose puppy classes that require vaccination records and hold sessions on cleanable surfaces.
Once your vet confirms the series is complete, build up to regular walks on the lead in public places.
Making dog vaccinations less stressful
A dog that has learnt that being handled predicts good things is easier and safer to vaccinate for the rest of its life. Practise at home: touch ears, paws and the scruff area briefly, then reward with a small, high-value treat, building duration slowly. Our guide to training with treats covers the size and value that work best. Take treats to the clinic too, and pair the waiting room and the scale with food. This is positive reinforcement applied to vet care, and it pays off far beyond vaccination day.
Vaccine reactions: what is normal
Mild, short-lived lethargy, a slightly reduced appetite or a tender injection site for a day or so are common and need no treatment. Go straight back to the vet if you see facial swelling, hives, vomiting, difficulty breathing or collapse after a vaccination. Serious reactions are uncommon but develop quickly, which is why many clinics ask you to wait a short while before leaving.
Boosters and titre testing
The three-year interval for adult core boosters reflects the long-lasting immunity that modified-live core vaccines provide. Some vets also offer antibody (titre) testing for the core diseases, which measures existing immunity and can show whether a booster is needed. It is worth discussing for older dogs or dogs with a history of reactions. It does not replace rabies vaccination, which remains a legal requirement on its own schedule.
