Prime100 (Australia)
Single-protein, limited-ingredient Australian range that does the elimination-diet job well and lists its ingredients clearly. The catch is cost: the rolls in particular work out expensive per kg for what's largely a simple recipe, and the sprawl of formats across air-dried, fresh and dry makes like-for-like value hard to pin down.
ZIWI Limited (New Zealand)
Genuinely high named-meat air-dried food with strong transparency — the ingredient panel is the real deal. But you pay heavily for it: among the highest price per kg and per serve in the category, and the value simply doesn't keep pace with the ingredient quality.
Both brands run through the same six-part model. Higher is better on every dimension; the forest dot marks the leader on each row.

Premium
Fair value and the rescue donations are real, not greenwash — but the food itself is good rather than exceptional, with mid-premium panels and a narrow range. Buy it because the per-kg value stacks up, not because the cause makes the ingredients better than they are.
Premium
A competent grain-free all-rounder, but it's mid-pack on every measure and now sits inside a big multi-brand portfolio where recipes have moved with ownership. Fine if the price is right on the day — just don't expect it to out-spec a more focused independent brand.
Premium
Fine on a discounted big bag if you choose a named-meat-first recipe, but don't assume the whole range is equal — the cheaper lines pad the panel with grain and rice, and a chunk of the price is reach and marketing rather than ingredients. Compare the specific formula on cost per kg against SavourLife and Ivory Coat.
On our value score, Prime100 edges ahead (72 vs 64). Value is about cost per day, not sticker price — compare the per-kg figures above and the cheapest retailer for each before deciding.
ZIWI Peak scores higher on ingredient quality (88 vs 83) in our index. We look at named-meat-first, protein source quality, wholefoods and fillers.
ZIWI Peak scores higher on transparency. Transparency covers ingredient clarity, country of manufacture, ownership and feeding-guide detail.
Online-only retailers like Pet Circle and Budget Pet Products are usually the price-to-beat on everyday pricing, while Petbarn is a strong all-rounder with the widest range, stores nationwide and competitive member and Repeat Delivery pricing. Whichever you choose, compare price per kg before buying.
