The Verified Label
Every food on this site gets this exact panel — same fields, same order, sourced from the official label — so brands finally become comparable. Corpus dot-anchors currently cover dry food only — this is a wet food, so anchors are omitted below rather than compared across forms.

No cost per 1,000 kcal: the label we read gives no calorie count, so we can't work out the price per calorie. Serving math uses standard veterinary energy formulas — see the formula.

4 ingredients in this list are ones we hold sourced evidence on , and none of them is contested in the veterinary literature.
- Mixed tocopherols (natural vitamin E) · ingredient 21Well 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.
- Guar Gum · ingredient 8NeutralA soluble, viscous fiber from the guar bean used in small amounts to thicken and stabilize foods, mostly wet formulas. At higher dietary inclusion it can lower the digestibility of dry matter and protein in dogs, but it also produces metabolic effects such as reduced post-meal insulin and cholesterol; at the low levels used as a thickener these effects are minor.
- 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.
- Taurine (supplemental) · ingredient 19NeutralA sulfur amino acid that dogs can normally synthesize from methionine and cysteine, so it is not classically essential for them. However, some breeds (e.g., golden retrievers) and some diets are linked to low taurine status and dilated cardiomyopathy: an observational study (Ontiveros 2020) associated non-traditional, largely grain-free diets with taurine deficiency and DCM-consistent echocardiographic changes in golden retrievers, though causation and mechanism remain under investigation.

Priced close matches
This food has no verified price yet — these are the closest label matches that do.
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.
Diamond Pet Foods owns and operates its own U.S. plants (Meta MO; Lathrop CA 1999; Gaston SC 2003; Ripon CA 2012; Dumas AR 2016; Frontenac KS 2021), where Diamond Naturals is produced.

source →No feeding-trial AAFCO statement found on the 25 labels we’ve verified for this brand, and no company-wide claim was found either. Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.
