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.
- 2protein 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.
- 3grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
- 4protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
- 5fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 6othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 7dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.
- 8oat groats
Whole oats with only the inedible hull removed. The most intact form of oats available.
- 9protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
- 10fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 11mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13psyllium seed husk
Soluble fiber. Supports stool quality. The same fiber humans use for digestive regularity.
- 14vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
- 15fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 16mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 17monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 18hydrolyzed yeast
Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.
- 19supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 20supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 21mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 22mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 23zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 24mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 25mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
