Read why each ingredient is good or bad for dogs.
- 1vegetablepotato
Standard white potato. Steady carb source, common starch in grain-free recipes.
- 2protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.
- 3protein plantpotato protein
Concentrated potato protein. Like pea protein, it inflates the protein number without matching meat-quality amino acids.
- 4fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 5othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 6fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
- 7mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 8fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 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.
- 11fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 12mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 13supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 14supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 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.
- 21mineralcopper proteinate
Copper bound to protein for better absorption. Common in better-formulated diets.
- 22mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
- 23preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 24preserved with mixed tocopherols and citric acid
