- 1corn starch
- 2hydrolyzed soy protein
- 3fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
- 4mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 5soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
- 6hydrolyzed chicken flavor
Hydrolyzed chicken used as a palatability enhancer. Real ingredient, tiny inclusion, no quality signal either way.
- 7ground pecan shells
- 8fatcoconut oil
Saturated fat with medium-chain triglycerides. Mostly marketing in the doses kibble uses, but harmless.
- 9lactic acid
Natural acid used as a mild preservative and pH adjuster. Found in fermented foods too. Safe at typical inclusion.
- 10mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
- 12glyceryl monostearate
- 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.
- 14dried citrus pulp
- 15supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 16fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 19pressed cranberries
- 20mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 21mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 22supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 23mineralmagnesium oxide
Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.
- 24mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 25zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
