Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for moderately active toy breeds like Cavalier King Charles Spaniels, Cocker Spaniels, and Shih Tzus navigating diet-associated DCM concerns. Chicken anchors position 1, with zero pulses in the top 15, plus chicken liver flavor at position 11 (a natural taurine precursor). The FDA's 2019 investigation update on diet-associated DCM included 13 reported cases in Cavalier King Charles Spaniels, making them one of the top 15 most frequently reported breeds at that time (FDA, 2019) .

Similar dog foods worth considering
Three lenses on products with formulation profiles similar to this one.
Surfaced from a vector similarity search across 3,491 scored dog foods. How this works.
Read why each ingredient is good or bad for dogs.
- 1protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 2: major carbohydrate source.
- 3cracked pearled barley
Pre-cracked pearled barley for better digestibility. Same whole-grain story.
Position 3. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.
- 4brewers 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 4: supporting grain. Smaller contribution to the carb deck.
- 5corn protein meal
Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 6: supporting grain. Smaller contribution to the carb deck.
- 7protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 7: supporting protein. Modest contribution to total protein weight.
- 8fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 8: trace fat. Below the level that materially shifts the fat profile.
- 9grainoats
Whole grain. Steady energy, soluble fiber, and well-tolerated by most dogs.
Position 9: minor grain inclusion.
- 10protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 10: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 11chicken liver flavor
Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.
Position 11. Small organ inclusion. Functional but not a primary contributor to the protein profile.
- 12pork liver flavor
Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.
Position 12. Small organ inclusion. Functional but not a primary contributor to the protein profile.
- 13soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
Position 13: trace fat. Below the level that materially shifts the fat profile.
- 14ground pecan shells
- 15lactic acid
Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.
- 16fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
- 17fiberdried 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 →
- 18dried citrus pulp
- 19mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 20supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 21fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 22pressed cranberries
- 23vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 24mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 25mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
