Bringing a new puppy home is exciting, but it also comes with important responsibilities—and vaccination is one of the most important.

As a veterinarian, one of the most common questions I’m asked is:“When should my puppy get their vaccines, and which ones are really necessary?”This guide explains which vaccines puppies need, when they should be given, and why timing plays a critical
role in protecting your puppy during their early months.

Why Puppy Vaccinations Are So Important

 

Puppies are born with developing immune systems. While their mother’s milk provides some early protection,
this natural immunity fades quickly.

Without timely vaccination, puppies are vulnerable to serious and potentially life-threatening diseases such as:

  • Parvovirus
  • Distemper
  • Hepatitis
  • Canine cough

 

Following the correct vaccination timing helps build strong, long-lasting immunity when puppies need it most.

When to Vaccinate Your Puppy

 

Vaccinations should begin early and follow a structured schedule. Most puppies receive their first vaccine
between 6 and 8 weeks of age, followed by booster doses at regular intervals.

Delaying or skipping vaccinations can leave your puppy exposed during their most vulnerable stage of development.

Puppy Vaccination Schedule (Vet-Recommended)

 

Below is a commonly followed vaccination timetable used by veterinary clinics across Australia.

Puppy’s Age Vaccination
6–8 weeks First DHPP vaccination
10–12 weeks Second DHPP vaccination
14–16 weeks Third DHPP vaccination
12 months Booster vaccination
Every 1–3 years Adult boosters (as advised)

DHPP protects against: Distemper, Hepatitis, Parvovirus, and Parainfluenza.

Note: Rabies vaccination is not required in Australia but may be needed for international travel.

Pro Tip: Even if your puppy appears healthy, vaccinations should never be delayed.

How Often Should Puppies Be Vaccinated?

 

One vaccine alone does not provide full protection. Puppies need a series of vaccinations because their
immune system matures gradually.

  • Vaccines are given every 3–4 weeks
  • The initial course continues until 16 weeks of age
  • A booster is given at 12 months, followed by adult boosters as recommended

Core vs Non-Core Puppy Vaccinations

 

Core Dog Vaccines

These are essential for all puppies and protect against highly contagious diseases:

  • Parvovirus – Causes severe vomiting and diarrhoea
  • Distemper – Affects the respiratory, digestive, and nervous systems
  • Canine Hepatitis – Serious liver disease
  • Parainfluenza – Contributes to kennel cough

Non-Core Vaccines (Lifestyle-Based)

  • Canine cough (Bordetella)
  • Leptospirosis

Your veterinarian will recommend non-core vaccines based on your puppy’s lifestyle and environment.

Pro Tip: Avoid public parks and dog play areas until the initial vaccination course is complete.

 

Why Vaccinating Your Puppy Matters

 

  • Reduces the risk of emergency medical care
  • Protects other pets in the community
  • Supports long-term health and immunity

Unvaccinated puppies face a significantly higher risk of severe illness during their first year.

 

When Can Puppies Go Outside After Vaccinations?

 

  • Controlled socialisation after the second vaccination
  • Public spaces once the full initial course is complete

This balance supports both disease prevention and healthy social development.

 

Common Puppy Vaccination Side Effects

 

Mild side effects may occur and usually resolve within 24–48 hours:

  • Temporary tiredness
  • Mild swelling at the injection site
  • Reduced appetite

 

Contact your veterinarian immediately if you notice severe reactions such as facial swelling,
vomiting, or breathing difficulty.
