Here are dog-food brands commonly sold in Australia that offer lines or formulas that emphasise high protein (with one or two example formulas and the brand-stated crude-protein levels):

• Orijen — biologically appropriate, meat-forward kibbles (e.g. Orijen Original: crude protein ~38%). (vetsupply.com.au)
• Acana — “protein-rich” WholePrey recipes (many adult formulas ~29–32% protein; some Singles/Sub‑zero styles are higher). (intl.acana.com)
• ZiwiPeak — air‑dried and canned whole‑prey recipes with very high meat content (air‑dried venison listed at ~45% crude protein; many air‑dried recipes 36–45%+). (world4pets.com.au)
• K9 Natural — New‑Zealand freeze‑dried/air‑dried formulas with very high meat content (many recipes 35–46%+ crude protein). (au.k9natural.com)
• Black Hawk — Australian brand with high‑protein grain‑free and working‑dog ranges (examples: grain‑free kangaroo ~28% crude protein; working/air‑dried formulas up to ~32–40%+). (blackhawkpetcare.com.au)
• Taste of the Wild — grain‑free kibbles with higher protein recipes (e.g. High Prairie ~32% crude protein). (store.petchemist.com.au)
• Nutrience (SubZero line) — premium “high‑protein” grain‑free range (several SubZero recipes list ~38% crude protein). (nutrience.com)
• Ivory Coat — Australian brand that markets several grain‑free / “raw health” recipes emphasising a high concentration of animal protein (typical adult formulas ~30%+). (peekapaw.com.au)

Notes and quick tips

• “High protein” is relative: kibbles marketed as higher‑protein are often in the ~30–40% crude‑protein range (as‑fed); air‑dried/freeze‑dried and canned whole‑prey style diets often report the highest percentages because they contain more meat and less carbohydrate. See the guaranteed analysis on the bag or product page to compare. (world4pets.com.au)
• If you need a recommendation for a specific dog (age, breed, activity level, health issues) or want me to compare the dry‑matter protein of particular formulas, tell me the exact product names and I’ll compare them side‑by‑side.
