Puppy Vaccinations: Protecting Your Pup from the Start

Puppies are playful, curious, and full of energy, but their immune systems are still developing. Vaccinations are the safest and most effective way to protect your puppy from serious, preventable diseases, and they play an important role in keeping the broader dog community healthy too.

Why Vaccinate?

When puppies are born, they receive some protection from their mother's milk. This borrowed immunity fades between four and twelve weeks of age, leaving a window of vulnerability before their own immune system is fully active. Vaccinations help bridge that gap and build lasting protection.

Some of the diseases we vaccinate against are highly contagious and can be fatal. Prevention is always the better path.

What Do We Vaccinate Against?

Distemper: A serious viral disease affecting the respiratory, gastrointestinal, and nervous systems. Can be fatal.

Hepatitis: A viral liver infection that can cause severe illness and death in unvaccinated dogs.

Parvovirus: Highly contagious and life-threatening, particularly in young puppies. Causes severe vomiting and diarrhoea. Parvo can survive in the environment for months.

Bordetella and Parainfluenza (Kennel Cough): The main components of kennel cough, a highly contagious respiratory illness. Vaccination is required for boarding, dog parks, and doggy daycare.

The standard Australian vaccination course for dogs is called a C5, which covers all five of the above.

Puppy Vaccination Schedule

• 6 to 8 weeks: First vaccination (C3: distemper, hepatitis, parvovirus)
• 10 to 12 weeks: Second vaccination (C5: adds bordetella and parainfluenza)
• 14 to 16 weeks: Third and final puppy vaccination (C5)
• 12 to 16 months: First adult booster
• Ongoing: Annual or triennial boosters as recommended

It is important to complete the full course. Kittens, puppies, and their immunity develop at different rates, and skipping or spacing out vaccines too far apart can leave gaps in protection.

When Can My Puppy Go Out?

Your puppy is not fully protected until approximately two weeks after their final puppy vaccination at 14 to 16 weeks. Until then, avoid high-risk areas like dog parks and public grassy spaces where unvaccinated dogs may have been.

That said, socialisation during this period is still very important. Safe options include visits to vaccinated friends' homes, puppy preschool (which we highly recommend), and carrying your puppy in low-risk outdoor settings. Ask us what is safe for your pup's current stage.

Common Questions

Are there side effects?
Most puppies handle vaccinations very well. Mild tiredness or slight tenderness at the injection site is normal for a day or two. Serious reactions are rare, and we monitor your puppy closely at every appointment. Contact us if you notice vomiting, swelling, or unusual behaviour after a vaccination.

Does my puppy really need boosters?
Yes. The immunity from vaccines does not last forever. Boosters maintain protection and ensure your dog can safely mix with other dogs, be boarded, and visit parks throughout their life.

What if we miss a vaccination?
Get in touch as soon as you can. Depending on how long the gap is, your puppy may need to restart part of the course. We will advise you on the best plan.

Puppy Preschool

We run Puppy Preschool here at Middle Brighton Vet, and we love it. It is a great way to socialise your pup with other vaccinated puppies in a safe environment while covering the basics of training and behaviour. Ask our team about upcoming classes.

After Your Puppy's Vaccination

• Keep your puppy calm and comfortable for the rest of the day
• Avoid strenuous activity for 24 hours
• Keep their vaccination certificate somewhere safe. You will need it for boarding, grooming, and travel
• Book the next vaccine before you leave so the schedule stays on track
