- 1protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
- 2cracked pearled barley
Pre-cracked pearled barley for better digestibility. Same whole-grain story.
- 3brewers 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.
- 4corn protein meal
Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.
- 5grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
- 6grainoats
Whole grain. Steady energy, soluble fiber, and well-tolerated by most dogs.
- 7ground pecan shells
- 8chicken liver flavor
Hydrolyzed chicken liver used as a flavor enhancer. Real ingredient, used in tiny amounts for palatability.
- 9fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.

Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.

Soluble fiber from sugar-beet processing. Sometimes treated as a filler, but it's actually one of the better fiber sources in kibble.
- 13pork liver flavor
Hydrolyzed pork liver used as a flavor enhancer. Same role as chicken liver flavor.
- 14dried citrus pulp

Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.

Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 21vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 22pressed cranberries
- 23supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 24mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
