Quality fat sources: named fat with marine oil (EPA and DHA source).
Quality carbohydrate sources with fermentable fiber.
AAFCO feeding trial substantiation for adult maintenance.
Plant-protein-dominated formula. brewers rice as the #1 ingredient.
Contains msg. Safety signal is internet-fueled; real issue is transparency. Yeast extract as MSG loophole obscures formulation..
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.

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.
- 2graincorn
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.
- 3protein 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.
- 4fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 5protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
- 6corn protein meal
Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.
- 7othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 8dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.
- 9fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
- 10vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
- 11fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 12sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 15mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 16potassium citrate
Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18yeast extract
Yeast broken down to a paste. Strong palatant plus a real source of B vitamins.
- 19supplementl-carnitine
Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.
- 20preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 21preserved with mixed tocopherols and citric acid
- 22supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 23supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 24supplementglucosamine hydrochloride
Joint-support compound. Most useful in larger doses for older dogs. The kibble dose is real but modest.
- 25supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
