10 ingredients in this list are ones we hold sourced evidence on , and none of them is contested in the veterinary literature.
- Named Meat/Poultry Meal (e.g., Chicken Meal, Lamb Meal) · ingredient 2Well supportedA rendered, water- and fat-reduced concentrate from a named species (AAFCO, e.g., 'chicken meal'). Because most moisture is removed it is a dense protein source (poultry meals commonly around 57-69% crude protein) and it names the species for allergy avoidance.
- Mixed tocopherols (natural vitamin E) · ingredient 9Well supportedA blend of vitamin E forms (alpha-, beta-, gamma-, delta-tocopherol) used as a natural-source antioxidant to slow fat rancidity, commonly chosen as an alternative to synthetic preservatives. EFSA concluded that tocopherol-rich extracts are safe for all animal species and the consumer and are efficacious antioxidants in feed.
- Rosemary extract · ingredient 65Well supportedA plant-derived natural antioxidant (active compounds carnosic acid and carnosol) used to slow fat oxidation, frequently chosen as an alternative to synthetic preservatives. It is an authorized food antioxidant in the EU (E 392); JECFA established a temporary acceptable daily intake for rosemary extract expressed as carnosic acid plus carnosol.
- Flaxseed (ALA omega-3) · ingredient 11NeutralA plant source of the short-chain omega-3 ALA. Dogs convert ALA to the long-chain omega-3s inefficiently: a controlled feeding study (Dunbar 2010) found flaxseed raised serum EPA but produced no measurable DHA.
- Prebiotics (chicory root / inulin, FOS) · ingredient 18NeutralFermentable fibers (chicory-derived inulin and fructooligosaccharides) that feed colonic bacteria and are readily fermented to short-chain fatty acids in dogs. Feeding studies show they shift fecal microbiota composition and are well tolerated at typical inclusion levels, but clear health benefits beyond compositional change are not yet established.
- Sweet potato · ingredient 23NeutralA starchy root used as a carbohydrate source and a source of fiber and beta-carotene in grain-free foods (a vegetable, not a cereal grain). The FDA's 2018 DCM investigation grouped 'potatoes (including sweet potatoes)' within its ingredients of interest, but the reported cases were dominated by pulses and white potato, and evidence isolating sweet potato specifically is limited.
Wet ingredients like fresh deboned duck shrink once cooked — which is why named meals appearing high on the list matter: they keep meaningful animal protein after moisture is removed.
Nutritional twins
Cheaper close matches
Verified foods with a closely matching label at a meaningfully lower cost per 1,000 kcal.
Label-composition matches only: same species, form, and growth stage; same primary protein where both are known; grain-free preserved; protein within 4 points and fat within 4 points, and estimated carbs within 8 points, on a dry-matter basis. Not a medical or quality recommendation.
The maker
Who makes this — and how they back it up
The five questions the WSAVA nutrition guidelines tell you to ask a pet-food company. Every answer is sourced or marked as an undisclosed gap — never guessed. This is the "is it made competently?" axis that star-rating sites skip.
