Vaccinations protect your puppy from diseases that are common, contagious and often deadly. The good news is that the schedule is straightforward. Here is what your puppy needs and roughly when — always confirm the exact timing with your own vet, as it varies by region and vaccine brand.
Why vaccination matters
Newborn puppies get some immunity from their mother’s milk, but it fades over the first weeks — leaving a window where they are vulnerable. Vaccines train the immune system to fight specific diseases before the puppy ever meets them. Skipping them puts your puppy, and other dogs, at real risk.
Core vaccines every puppy needs
- Parvovirus — a severe, frequently fatal gut infection.
- Distemper — attacks the nervous, respiratory and digestive systems.
- Canine hepatitis (adenovirus) — affects the liver and other organs.
- Parainfluenza — a contributor to kennel cough.
Depending on where you live and your dog’s lifestyle, your vet may also recommend leptospirosis, kennel cough (Bordetella) and rabies vaccines.
A typical puppy timeline
- 6 to 8 weeks: first core vaccination.
- 10 to 12 weeks: second vaccination.
- 14 to 16 weeks: final puppy vaccination.
- 12 months: first adult booster.
- Ongoing: boosters as advised by your vet.
Many boarding facilities, day-cares and dog walkers require proof of up-to-date vaccinations, so keep your records handy.
Socialising safely before full protection
The tricky part: the crucial socialisation window (up to about 16 weeks) overlaps with the period before full immunity. Do not lock your puppy away — under-socialised puppies grow into anxious dogs. Instead, socialise safely: invite calm, fully-vaccinated dogs to your home, carry your puppy to see the world, and attend puppy classes that require vaccination.
After the jab
Mild tiredness or a small lump at the injection site is normal for a day or two. Contact your vet promptly if you notice facial swelling, vomiting, or difficulty breathing, which can signal a rare reaction.
Keep records and stay on schedule
Missing boosters can leave gaps in protection. Set reminders, keep the vaccination card safe, and share a copy with any sitter, walker or boarding service who cares for your dog through Staunchify.
