What You Need to Know about Vaccinating Your Dog

Last updated on

Dog vaccinations are one of the most important steps in giving your puppy a healthy start in life. They prevent dogs from suffering from common illnesses like parvovirus, distemper, and canine hepatitis—all of which are still present in Australia today. 

The good news is that most of these are preventable with the right vaccination plan!

In this guide, we’ll walk you through the most important vaccines for dogs and share vet-backed insights on how to keep your furry friend safe and thriving. 

Whether you’re a first-time dog owner or simply need a refresher, this article will give you the confidence to stay on top of your dog’s health from day one.

Top dog illnesses that may be prevented by vaccines

Dogs, and especially puppies, are naturally curious and love to explore, but this also makes them vulnerable to serious and sometimes fatal diseases.

Below are the most common health problems in Australia that vaccines can protect your pup from.

Serious Viral Diseases
Parvo Virus (Parvo)A highly contagious viral disease causing severe vomiting, diarrhoea (often bloody), dehydration, and can be fatal, especially in puppies. Common in Australia.
DistemperA serious viral disease affecting the respiratory, gastrointestinal, and nervous systems. Symptoms may include fever, coughing, discharge from eyes/nose, seizures, and paralysis.
Canine Adenovirus (Hepatitis)Causes infectious canine hepatitis, damaging the liver, kidneys, and eyes. Signs may include fever, abdominal pain, jaundice, and in severe cases, sudden death.
Bacterial and Parasitic Diseases
Leptospirosis (in some Australian regions)A bacterial infection spread via contaminated water, soil, or urine of rodents/wildlife. Can cause kidney and liver damage, fever, vomiting, and is also a zoonotic disease (can infect humans).
Other Contagious Illnesses
“Kennel Cough” / Canine Cough (Bordetella & Parainfluenza)A contagious respiratory infection causing a persistent, hacking cough. While usually not fatal, it can weaken puppies and lead to complications like pneumonia.
Canine Influenza (emerging risk)A contagious respiratory illness causing coughing, fever, and nasal discharge. Outbreaks can spread quickly in areas with high dog populations.

Core Vaccinations in Australia

Your veterinarian is the best person to guide you on the right vaccination plan, tailoring it to your dog’s age, lifestyle, and the specific disease risks in your area. That said, here’s an overview of the core dog vaccinations every responsible pet owner should be familiar with.

What is the C3 Vaccination?

The C3 vaccine is a core vaccination for dogs that helps protect against three serious diseases:

  • Parvovirus
  • Canine Distemper Virus
  • Canine Adenovirus

These three viruses are considered “core” diseases, meaning they are a significant health threat and many dogs are at risk.

What is the C5 Vaccination?

The C5 Vaccination is basically the extension of the C3 Vaccination, with the addition of “non-core” vaccines against the following:

  • Parainfluenza virus (“Canine Cough”)
  • Bordetella bronchiseptica (“Canine Cough”)

The C5 Vaccination is highly recommended for dogs that socialise often, however it is important to discuss the recommended plan for your puppy or dog with your veterinarian.

What are Boosters?

Dogs should receive their core vaccinations and, when needed, booster shots to maintain immunity.

While vaccines offer strong protection, it usually lasts for a limited period, making boosters often required for long-term defence. 

Non-core vaccines are recommended based on your dog’s lifestyle and risk factors.

Puppy and dog vaccination schedule: Timing is key!

The timing of dog vaccinations is critical to ensure your puppy’s immune system develops the right level of protection. 

💡 Maternal antibodies—passed down from the mother—can sometimes block vaccines from working effectively, which is why a carefully spaced series of dog vaccinations is needed. 

Following your vet’s vaccination schedule of puppy shots and ongoing adult boosters helps avoid gaps in immunity against contagious diseases. 

By spreading vaccinations over several weeks, vets make sure each dose is given when maternal antibodies have faded and your puppy’s immune system is ready to build its own defences.

Here’s the standard dog vaccination schedule most vets recommend (please note this may vary based on the vaccination used and your vet’s recommendation):

Type of VaccineAge & Range Given
Initial VaccinesBetween 6-8 weeks old
First Booster VaccinesBetween 10-12 weeks old
Second Booster VaccinesBetween 14-16 weeks old
Annual Booster VaccinesApproximately 12 months after the last puppy second booster vaccine, then every 3 years

Vet tips for newly vaccinated dogs

After vaccination, keep an eye on your dog for any side effects. Offer a quiet, comfortable place to rest and make sure fresh water is available. 

Watch out for these side effects over the next 24–48 hours:

  • Mild reactions: tiredness, slight swelling, or soreness at the injection site (usually resolve within 1–2 days).
  • Serious reactions: difficulty breathing, hives, vomiting, or collapse — contact your vet immediately if these occur.

Avoid strenuous activities and limit contact with other animals for a few days. Your vet can let you know when it’s safe for your dog to return to normal activities and socialisation.

Preventative care for dogs beyond vaccinations

Vaccinations can give your dog a strong foundation of protection against common illnesses, but long-term health requires a more holistic approach.

From puppyhood to their senior dog years, regular preventive care is key to keeping your dog happy and healthy.

Scheduling at least an annual vet check-up provides an ongoing picture of your dog’s overall wellbeing. It also builds a stronger relationship with your vet, who can offer tailored advice based on a deeper understanding of your dog’s needs.

Another valuable step in preventive care may be enrolling in a wellness or routine care plan, which helps you stay consistent and proactive in managing your dog’s wellbeing.

What is a pet wellness or routine care plan?

A routine care plan is a subscription-based service that covers routine health care needs for your pet.

It covers services such as vaccinations, worm and flea prevention, and regular veterinary checkups. Unlike pet insurance, which covers unexpected medical expenses, wellness plans focus on preventative care.

Frequently asked questions about dog vaccinations

Most puppies begin their first vaccination at 6–8 weeks of age, with follow-up boosters at 10–12 weeks and 14–16 weeks. Your vet will confirm the best schedule for your puppy.

Booster vaccinations are recommended for adult dogs to maintain protection. Depending on the vaccine type and risk factors, boosters may be given annually or every three years. In many instances vaccinations are a requirement in order to attend facilities like “doggy daycare” and/or boarding kennels.

If your dog misses a scheduled vaccination, they may have reduced protection and be at risk of disease. Your vet can create a “catch-up” plan to get your dog back on track.

Most dogs experience no issues. Some may have mild side effects like tiredness or tenderness at the injection site, which usually resolve in 1–2 days. Severe reactions are rare, but you should contact your vet immediately if you notice difficulty breathing, hives, or collapse.

Core vaccines protect against diseases that are widespread and often severe (e.g., parvovirus, distemper, hepatitis, parainfluenza).

Non-core vaccines are recommended based on lifestyle or regional risks (e.g., bordatella, leptospirosis). Your vet will advise if these are necessary.

The cost varies depending on your vet, location, and whether additional non-core vaccines are needed. 

According to Finder’s 2024 vaccination cost guide, core vaccinations (C3) in Australia typically cost $100-200 per dose, while C5 and booster vaccinations range from $170-$250.

Aussie pet owners may use routine care plans or pet insurance extras to help cover vaccination costs.

While no vaccine provides 100% protection, vaccinated dogs have a much stronger immunity and are far less likely to develop severe illness if exposed.

No. Heartworm is prevented through monthly preventatives or annual injections, not vaccination. Knose’s Dog Essentials Plus Plan offers routine care with home-delivered parasite protection against the following: 

  • Heartworm
  • Tapeworm
  • Intestinal parasites
  • Ticks
  • Fleas
