8 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.
- Potato · ingredient 7ContestedA starchy tuber used as the carbohydrate base in many grain-free foods (it is a vegetable, not a cereal grain). The FDA's open 2018 investigation into diet-associated canine DCM listed potatoes 'in various forms' as main ingredients of interest alongside pulses such as peas and lentils.
- Named Meat/Poultry Meal (e.g., Chicken Meal, Lamb Meal) · ingredient 1Well 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 8Well 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.
- Flaxseed (ALA omega-3) · ingredient 10NeutralA 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.
- Taurine (supplemental) · ingredient 15NeutralA 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.
- Prebiotics (chicory root / inulin, FOS) · ingredient 16NeutralFermentable 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.
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 four 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 →The source refers to disciplines/experts (veterinary medicine, companion animal nutrition) but does NOT name any specific board-certified veterinary nutritionist (ACVN/ECVCN Diplomate) or PhD nutritionist on staff. Per rules, null.
source →No feeding-trial AAFCO statement found on the 31 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.
A reproducible PubMed search (author-affiliation field, animal/pet-domain filtered) returns zero indexed papers for this brand name. Not proof no research exists — only that none is PubMed-indexed under this exact name.
