5 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.
- Generic "Meat Meal" / "Poultry Meal" (unspecified species) · ingredient 2Worth knowingA rendered protein concentrate that does not name the species ('meat meal' is rendered mammal tissue; 'poultry meal' is rendered poultry without stating which bird). Nutritionally it behaves like a named meal, but the unnamed source means composition and digestibility can vary batch to batch and it cannot be used to avoid a specific-species allergy.
- Mixed tocopherols (natural vitamin E) · ingredient 6Well 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.
- Beet Pulp · ingredient 7Well supportedThe fibrous material left after sugar is extracted from sugar beets, included as a moderately fermentable fiber source (commonly around 5 to 7.5% of the diet). Controlled feeding studies show it supports firm, good-quality stools and short-chain fatty acid production without impairing overall nutrient digestibility, so the 'cheap filler' characterization is not supported by the evidence.
- By-Product Meal (Meat / Poultry By-Product Meal) · ingredient 4NeutralA rendered concentrate made from clean, non-muscle parts of the carcass (organs, necks, feet, and similar), defined by AAFCO. It is more variable and lower-transparency than a named muscle meal, but it is not inherently unsafe or low-nutrition: controlled feeding trials in dogs report high protein digestibility (roughly 92-95%) for poultry by-product-based diets, and some by-product organs are nutrient-dense.
- Probiotics (live microbials) · ingredient 13NeutralLive microbial supplements (e.g., Enterococcus faecium SF68, dried fermentation products) intended to support gut health. A 2019 JVIM systematic review found the effect on acute gastrointestinal disease in dogs limited and possibly clinically unimportant, and benefits appear strain- and context-specific: in one shelter trial SF68 significantly reduced diarrhea in cats but not in dogs.
Nutritional twins
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.
Facilities are described as Diamond's own in Meta, Missouri (HQ); Gaston, South Carolina; Lathrop, California; Ripon, California; Dumas, Arkansas; Frontenac, Kansas; and Rushville, Indiana. Diamond Pet Foods is well known industry-wide as a company that owns and operates its own plants rather than co-packing.
source →Diamond states it uses an internal team spanning veterinary medicine and companion-animal nutrition disciplines, but does not name a specific individual or state a board certification for any staff member on this or other pages found.
source →No feeding-trial AAFCO statement found on the 7 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.
