The score for this food is capped due to its low protein and high fat content on a dry matter basis. Nothing concerning in the deck regarding flagged ingredients.
Good fit for dogs needing a prescription diet for kidney and joint support. Less ideal if your dog requires higher protein levels.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Golden Retrievers and similar active sporting breeds navigating diet-associated DCM concerns. Chicken fat anchors position 2, with zero pulses in the top 15, plus pork liver flavor at position 11 (a natural taurine precursor). 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 49/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+17.5 points): Reasonable protein quality. brewers rice delivers solid amino acid coverage. A hard cap of 49 also applied because the guaranteed analysis falls below AAFCO's minimum nutrient profile. If a formula update that meets AAFCO minimums were on the label, the cap would lift and this formula could clear the B-band threshold (60).

Read why each ingredient is good or bad for dogs.
- 1brewers rice
Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version. See why →
Position 1 grain: primary carbohydrate base. This is a grain-inclusive formula with brewers rice as the dominant carb.
- 2fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 2: primary fat source. Drives the formula's caloric density and omega-6 content.
- 3fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 3: primary fat source. Drives the formula's caloric density and omega-6 content.
- 4protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5protein animalegg product
Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.
Position 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 6. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 7hydrolyzed chicken flavor
Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.
- 8fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 8: functional fiber for digestion or satiety.
- 9protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 9: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 10fiberdried beet pulp
Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble. See why →
Position 10: functional fiber for digestion or satiety.
- 11pork liver flavor
Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.
Position 11. Small organ inclusion. Functional but not a primary contributor to the protein profile.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13lactic acid
Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 15supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 16betaine
- 17lipoic acid
- 18potassium citrate
Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.
- 19grainoats
Whole grain. Steady energy, soluble fiber, and well-tolerated by most dogs.
- 20supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 21l-threonine
Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.
- 22supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 23fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 24calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 25mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
