- 1protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken.
- 2grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
- 3oat groats
Whole oats with only the inedible hull removed. The most intact form of oats available.
- 4legumepeas
Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
- 5fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 6
- 7grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
- 8dried yeast
Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.
- 9fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11dried eggs
Whole eggs. The highest-quality protein on any ingredient label by amino acid score.
- 12dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14fatsunflower oil
Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.

Prebiotic fiber that supports gut bacteria. A genuine functional ingredient, not marketing.
- 16supplementyucca schidigera extract
Plant extract added to reduce stool odor. Functional, not nutritional. Fine in trace amounts.

Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 19mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 20mineraliron sulfate
- 21mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 22mineraliron proteinate
Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.
- 23mineralcopper proteinate
Copper bound to protein for better absorption. Common in better-formulated diets.
