Nothing concerning in the deck.
Good fit for adult dogs, especially those needing a limited ingredient diet. Nothing serious working against it.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Golden Retrievers navigating diet-associated DCM concerns. Duck by-product meal anchors position 2, with zero pulses in the top 15. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Sniff scored this formula 58/100, landing in C-tier (acceptable-with-notes). The biggest contributor was fat quality (+12 points): Quality fat sources: named fat with marine oil (EPA and DHA source). Also adding to the lift: carbohydrate quality (+12). Quality carbohydrate sources with declared fiber. The 2-point gap to B-tier sits mostly in protein quality (11 of 27 possible). Full protein quality requires named-species named-cut proteins in the top of the deck (e.g., "deboned chicken" rather than "chicken meal" or "poultry meal").
Quality fat sources: named fat with marine oil (EPA and DHA source).
Quality carbohydrate sources with declared fiber.
AAFCO feeding trial substantiation for adult maintenance.

Read why each ingredient is good or bad for dogs.
- 1vegetablepotato
Standard white potato. Steady carb source, common starch in grain-free recipes.
Position 1: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 2duck by-product meal
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3fatcoconut oil
Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.
Position 3: primary fat source. Drives the formula's caloric density and omega-6 content.
- 4protein plantpotato protein
Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.
Position 4: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 5hydrolyzed soy protein
- 6othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 7vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 8. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 9monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 10supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 11supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 15mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 16zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 17mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 18mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 19manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 20mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 21mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 22mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
- 23mineralcopper proteinate
Copper bound to protein for better absorption. Common in better-formulated diets.
- 24supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 25supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
