Every flag above is computed from this list. Why order is by pre-cooking weight, and how splitting bends it →
Chicken, rice, corn protein meal, whole grain corn, poultry by-product meal, whole grain wheat, beef fat preserved with mixed-tocopherols, pea fiber, dried egg product, fish meal, natural flavor, fish oil, soybean oil, mono and dicalcium phosphate, salt, potassium chloride, potassium citrate, L-Lysine monohydrochloride, choline chloride, MINERALS [zinc sulfate, ferrous sulfate, manganese sulfate, copper sulfate, calcium iodate, sodium selenite], VITAMINS [Vitamin E supplement, niacin (Vitamin B-3), Vitamin A supplement, calcium pantothenate (Vitamin B-5), thiamine mononitrate (Vitamin B-1), Vitamin B-12 supplement, riboflavin supplement (Vitamin B-2), pyridoxine hydrochloride (Vitamin B-6), folic acid (Vitamin B-9), menadione sodium bisulfite complex (Vitamin K), Vitamin D-3 supplement, biotin (Vitamin B-7)], calcium carbonate, garlic oil
5 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.
- Peas · ingredient 8ContestedA pulse (legume) used in many grain-free foods as a plant protein and carbohydrate source. Peas are central to an open FDA investigation, begun in July 2018, into a possible link between diets high in peas, other pulses, and potatoes and canine dilated cardiomyopathy (DCM); 93% of reported products contained peas and/or lentils.
- Mixed tocopherols (natural vitamin E) · ingredient 7Well 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.
- Named Meat/Poultry Meal (e.g., Chicken Meal, Lamb Meal) · ingredient 10Well 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.
- Fish oil (EPA + DHA omega-3) · ingredient 12Well supportedMarine-source omega-3 fatty acids (EPA and DHA) from fish oil. A randomized, double-blinded controlled trial (Roush 2010) found improved weight-bearing in dogs with osteoarthritis, and a 2022 meta-analysis identified clear clinical analgesic efficacy for omega-3-enriched diets and supplements.
- By-Product Meal (Meat / Poultry By-Product Meal) · ingredient 5NeutralA 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.
Wet ingredients like fresh chicken 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.
