Read why each ingredient is good or bad for dogs.
- 1protein animallamb
Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.
- 2protein animallamb meal
Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb.
- 3grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
- 4cracked pearled barley
Pre-cracked pearled barley for better digestibility. Same whole-grain story.
- 5grain sorghum
Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.
- 6dried yeast
Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.
- 7protein animalegg product
Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.
- 8fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 9grainwhite rice
Refined grain with the bran stripped off. Easy to digest, but not as nutrient-dense as brown rice.
- 10protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.
- 11dried tomato pomace
The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.
- 12othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 13fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
- 14fatsalmon oil
Pure omega-3s. The thing skin-and-coat formulas are usually built around.
- 15mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 16supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 17mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 18supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 19supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 20fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 21supplementl-carnitine
Amino acid derivative that helps the body convert fat into energy. Common in weight-management formulas.
- 22vegetablekale
Leafy green with antioxidants and fiber. Small dose in kibble, but it's not just for marketing.
- 23chia seed
Plant source of omega-3 and fiber. Like flaxseed, useful in trace amounts.
- 24vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 25fruitblueberries
Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.
