Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →
Read why each ingredient is good or bad for dogs.
- 1protein animalbeef
Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.
- 2protein animallamb meal
Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb.
- 3vegetablesweet potato
Complex carb with fiber and beta-carotene. Gentle on the stomach.
- 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 →
- 5legumelentils
Same concern as peas. Affordable plant protein, but when they pile up in the top 5 ingredients, it's a flag. See why →
- 6legumepea flour
Powdered peas, usually used as a binder or filler. Counts toward the legume stack the FDA flagged.
- 7fatcanola oil
Plant oil. Some omega-3 from the parent plant, though dogs absorb it less efficiently than fish-derived omega-3. Fine in moderation.
- 8dried tomato pomace
The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.
- 9protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
- 12fatsalmon oil
Pure omega-3s. The thing skin-and-coat formulas are usually built around.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 15supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 16supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 17fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 18supplementyucca schidigera extract
Plant extract added to reduce stool odor. Functional, not nutritional. Fine in trace amounts.
- 19tomatoes
Real fruit. Lycopene and trace antioxidants. Different from tomato pomace, which is the fiber byproduct.
- 20fruitblueberries
Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.
- 21fruitraspberries
- 22probioticdried lactobacillus plantarum fermentation product
- 23probioticdried bacillus subtilis fermentation product
- 24probioticdried lactobacillus acidophilus fermentation product
A probiotic strain. Whether the dose is high enough to actually colonize is debated, but it's a real beneficial bacterium.
