Vaccinations are one of the most important things you'll do to protect your new puppy — they prevent serious, often fatal diseases. The schedule can look confusing at first, so here's a clear overview of what puppies typically need and when. One important note up front: exact schedules vary by country, region, and your puppy's circumstances, so your veterinarian's plan always takes precedence over any general guide.
Core vs. non-core vaccines
Vaccines are generally grouped into 'core' (recommended for essentially all dogs because the diseases are widespread and dangerous) — a framework set out in the 2022 AAHA Canine Vaccination Guidelines, which list distemper, adenovirus, parvovirus and rabies as core for every dog, and in 2022 moved leptospirosis to core for most dogs based on where the disease now occurs and 'non-core' (given based on lifestyle and risk). Your vet will recommend which non-core vaccines make sense for your dog based on where you live and what your dog does.
- Core typically protects against diseases like distemper, parvovirus, adenovirus/hepatitis, and rabies (rabies requirements vary by country/region)
- Non-core may include things like kennel cough (Bordetella), leptospirosis, or Lyme disease, depending on risk
- Which non-core vaccines your dog needs is a conversation to have with your vet
The typical puppy timeline
Puppies usually receive a series of vaccinations every few weeks starting from around 6-8 weeks of age, continuing until about 16 weeks, with boosters later. The reason for the series is that immunity passed from the mother gradually fades, and the spaced doses make sure the puppy stays protected as it does. Your vet will give you the exact dates.
- Roughly 6-8 weeks: first vaccinations often begin
- Every 2-4 weeks after: follow-up doses in the series
- Around 12-16 weeks: final puppy doses (rabies often given here where required)
- Boosters: at around one year, then periodically as your vet advises
Why you shouldn't fully socialize before the series is done
Until your puppy's vaccination series is complete, they're vulnerable to diseases like parvovirus, which can linger in the environment. That's why vets advise avoiding dog parks and unknown dogs early on — while still safely socializing in controlled ways (see our puppy socialization guide for how to do this safely).
American Red Cross Pet First Aid Kit
A ready-stocked pet first-aid kit is worth having from day one for minor scrapes and to stabilise your puppy while you get to the vet. It doesn't replace veterinary care and isn't a substitute for your vet's vaccination plan — think of it as a sensible safety net between visits.

Vaccinations are essential, and the series matters. Use this as a general map, but follow the precise schedule your veterinarian gives you — it's tailored to your puppy, your region, and the current guidance. Keep a record of each vaccination for boarding, training classes, and travel.
Frequently asked questions
When should a puppy get its first vaccinations?
Puppies typically begin their vaccination series at around six to eight weeks of age, with follow-up doses every two to four weeks until roughly sixteen weeks. The exact timing depends on your region and your puppy's circumstances, so your veterinarian's schedule is the one to follow. Always confirm the dates with your vet rather than relying on a general guide.
What vaccines does a puppy actually need?
Core vaccines — generally recommended for all dogs — protect against diseases like distemper, parvovirus, and adenovirus/hepatitis, with rabies required in many areas. Non-core vaccines such as Bordetella (kennel cough), leptospirosis, or Lyme are given based on lifestyle and local risk. Your vet will advise which non-core vaccines make sense for your dog.
Can my puppy go outside before finishing their vaccinations?
Your puppy can start safe, controlled socialization before the series is complete, but you should avoid dog parks and unknown dogs until your vet says it's safe, because diseases like parvovirus can linger in the environment. Carrying your puppy and inviting healthy vaccinated dogs to your home are lower-risk options. Ask your veterinarian what's appropriate given your puppy's progress and local risk.
Are puppy vaccinations safe?
Vaccinations are considered very safe and are one of the most important ways to protect your puppy from serious, often fatal diseases; mild, short-lived side effects like tiredness or soreness can occur. Serious reactions are rare. Discuss any concerns, or your puppy's individual health, with your veterinarian.
