Graded by The Sniff System
Quality carbohydrate sources with fermentable fiber.
Quality fat sources: named fat with marine oil (EPA and DHA source).
AAFCO feeding trial substantiation for adult maintenance.
Plant-protein-dominated formula. corn as the #1 ingredient.
Controversial ingredients · 1
- sodium seleniteSynthetic selenium source. Selenium is essential, but sodium selenite has a narrower safety margin than organic alternatives like selenium yeast. Better-formulated foods use the organic form.

- 1graincorn
Whole corn is more nutritious than it gets credit for, with decent amino acids and steady carbs. The bigger concern is when corn dominates the top of the ingredient list at the expense of named meat.
- 2brewers 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.
- 3grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
- 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.
- 5protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
- 6fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
- 7fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 8fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 9othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 10mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 11protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
- 12vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 15fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 16monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 17supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 18fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 19supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 20supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 21supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 22zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 23mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 24manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 25mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
