ChatGPTDog vaccinations can feel a little alphabet-soupy at first, but C3 and C5 are not nearly as mysterious once you know how simple the naming logic is. C stands for canine, and the number tells you how many disease components are covered. And while this pearl of pet-parent trivia may not make it to dinner party chat, it does make the dog vaccination schedule much easier to understand.
In Australia, C3 protects pups against three serious diseases: parvovirus, distemper and infectious hepatitis. C5 includes those same protections plus adds coverage for Bordetella and parainfluenza, two major contributors to canine cough. For dogs who love a playdate, daycare day or boarding stay, that extra canine cough protection helps keep shared spaces safer for every type of pup party.
To join the fun at Kip, dogs must be up to date with their C5 vaccination before attending dog boarding or dog daycare. It’s one of the ways we help protect every pooch in our care.
What C3 and C5 actually cover
C3 and C5 are combination vaccines, meaning each one protects against more than one disease. In Australia, C3 is the core vaccine most pups receive as part of their routine dog vaccination schedule.
C3 vaccine for dogs protects against canine parvovirus, canine distemper and canine adenovirus (also known as infectious hepatitis). C5 includes the same C3 protection, and adds coverage for Bordetella bronchiseptica and canine parainfluenza virus, two major causes of contagious canine cough.
| Vaccine Code | Components | Diseases Covered | Typical Interval |
|---|---|---|---|
| C3 | Canine parvovirus, canine distemper virus, canine adenovirus | Parvovirus, distemper, infectious hepatitis | Usually given as pup’s first vaccination at 6–8 weeks, then forms part of ongoing core protection. Adult boosters are given according to vet advice (approximately every 1–3 years). |
| C5 | Canine parvovirus, canine distemper virus, canine adenovirus, plus Bordetella bronchiseptica and canine parainfluenza virus | Parvovirus, distemper, infectious hepatitis and canine cough protection | Often introduced as the second puppy vaccination around 10–12 weeks, then typically boosted annually for the canine cough components, especially for boarding, daycare and social doggos. |
You may also hear your vet mention the C7 vaccine. It includes extra components such as leptospirosis and coronavirus, but it is typically considered risk-based rather than routine for most Australian dogs. Your vet will look at where your dog lives, where they go and what they may be exposed to before recommending it.
This reflects AVA and WSAVA VGG guidance, which separates dog vaccines into core and non-core categories. Core vaccines cover the big ones every dog needs protection from. Non-core vaccines are recommended based on where your dog lives, plays, sniffs and socialises.
Puppy vaccination schedule in Australia
Puppies build their protection in stages, so the dog vaccination schedule is usually spread across three vet visits. In Australia, a common puppy vaccination schedule looks like this:
| Puppy Age | Vaccination Step |
|---|---|
| 6-8 Weeks | C3, core vaccination covering parvovirus, distemper and infectious hepatitis |
| 10-12 Weeks | Booster, often C5, adding canine cough protection to the core C3 coverage |
| 14–16 Weeks (with many vets aiming for 16 Weeks) | Often C5 again, completing the puppy course before ongoing boosters. |
The first C3 is given early because puppies need core protection as the natural immunity they received from mum starts to fade. The C5 vaccine for dogs is often introduced at the second puppy vaccination, when your pup is ready for canine cough protection.
This timing can feel awkward because it overlaps with another important puppy job: learning how to be a dog in the world. Puppies can usually begin structured socialisation before their full vaccination course is complete, as long as it happens with the right controls in place. That does not mean heading straight for the busiest dog park around and letting your pup greet every snout on the street. It means clean puppy classes, vaccinated dog friends and supervised introductions, guided by your vet's advice for your local area.
Adult dog boosters and the annual vs triennial debate
Hold on to your doggie biscuits, because this is where the vaccine jargon gets a little chewy. When people talk about the dog booster vaccination schedule, there are usually two clocks running at once.
The first clock is for C3, the core protection against parvovirus, distemper and infectious hepatitis. Under the current guidance, these core components may only need to be boosted every three years in adult dogs, once their puppy course and first adult booster are complete.
The second clock is for canine cough protection, which is part of C5. This protection is usually topped up every year, especially for dogs who love the social life, enjoy dog boarding, or go to daycare, grooming, training or group play.
So your dog can be up to date with their three-year core vaccination and still need the annual canine cough top-up that the C5 provides before boarding or daycare. Confusing? A little. Common? Very.
The advice has shifted over time, which adds to the booster blur. Some Australian vets moved to three-year core boosters earlier than others, while some kept annual core boosters for longer. (No wonder the calendar can feel a bit hairy). Your vet can confirm what your dog needs now: core protection, canine cough protection, or both.
For Kip, dogs need a current C5 vaccination before joining dog boarding or dog daycare. If your pup is on a three-year core schedule, ask your vet to confirm their canine cough protection is current, too. Then everyone can get on with the good stuff: safe play, comfy rest and happy zoomies.
Titre testing and vaccination exemptions
By now, you’re pretty close to becoming the person at the dog park who can translate vaccine certificates for everyone. There is one more term worth knowing.
A titre test is a blood test your vet can use to check whether your dog still has measurable antibodies against certain core diseases. This can be useful for some pups, especially senior dogs, dogs that have had a previous vaccine reaction, or dogs with immune conditions where your vet wants to be extra careful. It gives your vet more information before deciding whether a core booster is needed.
Titre testing, however, does not measure canine cough protection. That means a titre result cannot replace the Bordetella and parainfluenza parts of C5, which are the components most relevant for boarding, daycare and other social dog environments.
If your vet has recommended titre testing or a vaccination exemption for your dog, please contact Kip before booking. While we’re happy to discuss your circumstances, we do not accept titre testing as a replacement for required vaccinations. Unfortunately, because our facilities are shared environments, we may not be the right fit for dogs that don’t meet our vaccination requirements.
What Australian boarding and daycare facilities require
The industry standard for dog vaccinations in Australia for boarding and dog daycare is a current C5 vaccination, usually given within the last 12 months and at least 7–14 days before your doggo’s stay.
Requirements can vary between providers. Some accept a recent vaccination certificate, while others may need extra documentation for medical exemptions or titre testing.
At Kip, dogs need to be up to date with their C5 vaccination before joining dog boarding or dog daycare.
Vaccinations for rescue or adopted dogs without records
If you have adopted a dog and their vaccination history is missing or unclear, your vet will usually treat them as unvaccinated and restart the schedule. That often means beginning with the C3 vaccine for dogs, then adding C5 so your dog has both core protection and canine cough coverage.
Your vet can confirm the right timing based on your dog’s age, health and any information from the rescue group or previous carer. For boarding or dog daycare, your pup will usually need a current C5 certificate, and you may need to wait 7–14 days after vaccination before joining social activities.
Side effects, risks and when to call your vet
Most dogs handle vaccinations with very little fuss, though some may be a bit flat afterwards. Mild side effects can include:
- Sleepiness
- Tenderness at the injection site
- Lower appetite
These mild reactions usually settle within 24–48 hours. Keep your dog comfy, offer water, and let them have a couch day if they need it.
Reactions that are a red flag and need urgent vet attention are :
- Facial swelling
- Hives
- Repeated vomiting
- Collapse
- Difficulty breathing
- Severe weakness
- Any reaction that feels sudden or serious
You may also hear about vaccine-associated sarcomas. These are exceptionally rare in dogs, but any lump that appears after vaccination and does not settle should be checked by your vet. When in doubt, make the call.
Cost expectations across Australia
Dog vaccination schedule costs vary across Australia, and there is no single standard fee. As a rough guide:
- C3 vaccinations sit around $80–$150
- C5 vaccinations are typically around $100–$180
Costs depend on the clinic, location and whether the consultation is included. Capital-city clinics may charge differently to regional clinics, and prices can also shift between suburbs.
Titre testing usually costs more than a standard vaccination because it involves a blood test and lab work.

Frequently Asked Questions
Is C5 mandatory for dog boarding in Australia?
Usually, yes. The C5 vaccine for dogs is commonly required for dog boarding in Australia because it includes canine cough protection as well as the core C3 components.
Can my dog board on just a C3 vaccination?
Not at Kip. Your dog usually can’t be boarded on just a C3 vaccine. C3 covers core diseases, but it doesn’t include canine cough protection.
How much does a C5 vaccination cost in Australia?
A C5 vaccination in Australia often costs between $100 and $180 depending on the vet clinic and location. Prices can vary between capital cities, suburbs and regional areas, so check with your local vet before booking.
How long does the C5 vaccine last?
The C5 vaccine for dogs usually lasts a year for the canine cough components, which is especially relevant for dogs heading into boarding, daycare, grooming, training or group play. The core C3 components may still carry protection, but the canine cough part has its own calendar, and that yearly top-up is the bit social pups need to keep current.
Can puppies socialise before they’re fully vaccinated?
Pups can start socialising before they’re fully vaccinated as long as it's structured and safe. That means clean puppy classes and play dates with vaccinated puppy pals. Big dog parks with lots of ruff and tumble will have to wait.
Does Kip accept titre testing instead of vaccinations?
No. At this stage, Kip does not accept titre testing as a substitute for required vaccinations. To help protect the health and wellbeing of all pets in our care, dogs and cats must meet Kip's vaccination requirements before their stay. If you're unsure which vaccinations your pet needs, please get in touch with your local Kip location.
