11 ingredients in this list are ones we hold sourced evidence on , and 3 of them are genuinely contested rather than merely unpopular online.
- Chickpeas (garbanzo beans) · ingredient 3ContestedA pulse (legume), also called garbanzo bean, used in grain-free foods for plant protein and carbohydrate. Chickpeas are among the pulses (with peas and lentils) cited in the FDA's open 2018 investigation into diet-associated canine DCM.
- Potato · ingredient 4ContestedA 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.
- Lentils · ingredient 6ContestedA pulse (legume) common in grain-free formulas as a protein and carbohydrate source. Lentils are named alongside peas in the FDA's open 2018 investigation into diet-associated canine DCM; the agency grouped 'peas and/or lentils,' which appeared in 93% of reported products.
- Named Muscle Meat (e.g., Deboned Chicken, Beef, Salmon) · ingredient 1Well supportedA named fresh muscle meat identifies both the species and that it is clean flesh (AAFCO defines 'meat' as the clean flesh of a specified slaughtered mammal, and 'poultry' as clean flesh and skin). Naming the species is what lets an owner verify a protein for allergy avoidance.
- 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 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.
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.
Nutro FAQ (nutro.com/faqs) adds: 'We have two dry pet food manufacturing facilities for NUTRO products located in Henderson, North Carolina, and Victorville, California.' Some products are co-packed abroad (SO SIMPLE trays made in Thailand per the FAQ), so it is not exclusively self-owned, but dry food is made in Mars-owned US plants — primary answer 'owns' with minor co-pack exception.

source →No feeding-trial AAFCO statement found on the 84 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.
