What is the cheapest dog food online in Australia?
The cheapest bag is not always the cheapest feed.
Key insightA budget food can cost less per kg but need a bigger daily serve, so always check the cost per day, not just the sticker price. We show you both, so you can see what it really costs to feed.

Price per kg and cost per day
Cost per day assumes a ~15kg adult dog fed to the brand's feeding guide. Indicative pricing, a guide only — do check the live prices before you buy.
We compare a standardised basket — not cherry-picked deals.
Same products, same sizes, every retailer — so the cheapest store really is the cheapest, not just the one shouting loudest about a sale.

Frequently asked questions
By price per kg, Black & Gold (Black & Gold Adult Dry Dog Food Beef & Vegetables 8kg) is the cheapest in our index at $2.25/kg. But the cheapest bag isn't always the cheapest feed. A lower-scoring food can cost less per kg and still need a bigger serving, so check the cost per day too: Purina Pro Plan comes out lowest there.
On our standardised sample basket, Aldi comes out cheapest ($160), with Woolworths and Coles not far behind. For everyday mainstream dry food, Pet Circle and Budget Pet Products are usually the ones to beat.
Cheaper foods are often less dense, so your dog needs a bigger serving to get the same nutrition. That quietly eats into the saving, or wipes it out altogether. Always compare cost per day, not just the sticker price or price per kg, to see what it really costs to feed.
Yes. Online-only retailers like Pet Circle and Budget Pet Products often post the lowest everyday prices, but Petbarn holds its own — its member and Repeat Delivery pricing is very competitive, and you get the widest range and stores nationwide on top. Whichever you go with, it's worth comparing price per kg before you buy.
No, and we'd rather say so plainly. Pet Reviews is an independent value and comparison resource, not veterinary advice. Prices are a guide and can change, so always confirm the live price with the retailer before you buy.
