Read why each ingredient is good or bad for dogs.
- 1protein 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.
- 2grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
- 3oat groats
Whole oats with only the inedible hull removed. The most intact form of oats available.
- 4grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
- 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.
- 6brewers 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.
- 7fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 8othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 9dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.
- 10protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
- 11fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 12vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
- 13sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 14mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 15mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 16powdered psyllium seed husk
- 17fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 18mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 19supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 20preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 21preserved with mixed tocopherols and citric acid
- 22mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 23supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 24supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 25mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
