Annual cost by category and breed size (AUD)
| Category | Small | Medium | Large | Giant |
|---|---|---|---|---|
| Food & treats 5-10 kg dry food/year | $380 – $620 | $550 – $850 | $750 – $1,150 | $950 – $1,500 |
| Vet (routine + preventatives) Check, vaccines, parasite control | $380 – $720 | $420 – $820 | $480 – $950 | $560 – $1,150 |
| Insurance (accident & illness) $32-60/month | $380 – $720 | $460 – $880 | $540 – $1,020 | $640 – $1,240 |
| Grooming Short coats near zero | $80 – $320 | $120 – $480 | $150 – $560 | $180 – $720 |
| Boarding / pet sitting $40-60/night | $150 – $900 | $200 – $1,000 | $250 – $1,150 | $300 – $1,350 |
| Annual total (mid-point) | $2,325 | $2,890 | $3,500 | $4,295 |
Ranges are indicative, benchmarked to Canstar's cost-of-a-dog survey and RSPCA vet-cost averages. Boarding is the widest band because it is discretionary — owners who do not travel sit at the low end of every range.
What drives the size gap
The $1,175 a year gap between a small and a large dog is not spread evenly. Food alone accounts for roughly $450 of it — a large dog simply eats two to three times as much. Insurance adds another $230 because larger breeds generate bigger surgical claims. Vet and grooming scale more modestly; boarding carries a per-night size surcharge.
The practical takeaway: if annual cost matters, breed size is the single biggest lever — bigger than diet tier, bigger than insurance excess choice. A small dog on premium food still costs less per year than a large dog on supermarket dry.
Dog cost per year — FAQ
How much does a dog cost per year in Australia?
A typical Australian dog costs between $1,358 and $1,683 a year across the five real cost categories — food, vet, insurance, grooming and boarding — with small breeds near $1,358 and large breeds near $1,683. The mid-point across all sizes is about $1,520. Giant breeds (40 kg+) push above $1,900 a year once food, boarding surcharges and higher insurance loadings are included. These figures are recurring annual costs for a dog you already own; they do not include the purchase price, desexing or the first-year puppy vaccinations.
Why does a large dog cost more per year than a small dog?
Three lines drive the gap: food (a Labrador eats 2-3 times what a Frenchie eats, adding roughly $300-500/year), insurance (larger dogs generate bigger surgical claims, so premiums run $45-85/month versus $32-60 for small dogs), and boarding (kennels charge a size surcharge, $50-70/night versus $40-60). Vet and grooming also scale with size but more modestly. Together these move the annual total from about $1,358 for a small dog to $1,683 for a large dog.
How much is dog food per year in Australia?
Roughly $380-620 a year for a small dog, $550-850 for a medium dog, $750-1,150 for a large dog and $950-1,500 for a giant breed, depending on whether you feed supermarket dry or a premium formula. Premium dry adds about 25% over standard. Treats, chews and the occasional wet food top-up add another $80-200 a year on top of the staple food line.
How much is dog insurance per month in Australia?
Accident-and-illness cover runs about $32-60/month for a small dog, $38-73 for a medium dog, $45-85 for a large dog and $53-103 for a giant breed. Premiums climb with the dog's age and with breed-specific loadings — bulldogs, mastiffs and other breeds with known hereditary conditions sit at the top of each size band. Canstar's annual pet insurance research is the most-cited benchmark for these ranges.
Is the boarding cost avoidable?
Largely yes, which is why boarding has the widest range of any category on this page. If you never travel, or use a friend or family member, the line is close to zero. If you kennel the dog for two weeks a year at $45-70 a night, that alone is $630-980 — enough to push a medium dog from the low end of the annual range to the high end. Boarding is the single biggest discretionary lever in the annual cost.
How do these numbers compare to Canstar and RSPCA figures?
They are in the same band. Canstar's most recent cost-of-a-dog survey puts the annual total at roughly $1,400-2,000 depending on size and lifestyle; the RSPCA's ownership-cost guidance lands in a similar range. The breakdown on this page uses those sources for the category mid-points and splits the total explicitly by breed size so you can read off the number that matches your dog rather than a population average.
