Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. At 300 kcal/cup this formula runs on the lean side, with crude fiber at 4% (above the catalog median, supports satiety). The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

Sniff scored this formula 66/100, landing in B-tier territory. The biggest contributor was protein quality (+18.5 points): Reasonable protein quality. brewers rice delivers solid amino acid coverage. Also adding to the lift: carbohydrate quality (+13). Quality carbohydrate sources with fermentable fiber. The 9-point gap to A-tier sits mostly in protein quality (18.5 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").

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.
- 2protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 2: 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.
- 3protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4protein animalchicken by-product meal
Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about. See why →
Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5hydrolyzed chicken flavor
Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.
- 6fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8ground pecan shells
- 9pork liver flavor
Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.
Position 9. Functional organ inclusion. Adds amino acids and micronutrients even at smaller weight.
- 10lactic acid
Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.
- 11fish flavor
- 12supplementginger
Real spice. Some anti-nausea evidence in humans, but the dose in kibble is small. Mostly for flavor.
- 13fiberdried 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 13: trace fiber inclusion.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15potassium citrate
Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.
- 16dried citrus pulp
- 17mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 18supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 19calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 20mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 21glyceryl monostearate
- 22pressed cranberries
- 23supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 24supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 25mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
