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.
- 2grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
- 3corn protein meal
Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.
- 4grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
- 5protein animalpoultry by-product meal
Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.
- 6grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
- 7grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
- 8beef fat preserved with mixed-tocopherols
Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.
- 9corn germ meal
- 10protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile.
- 11dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
- 12othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 13fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 14wheat bran
- 15mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 16soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
- 17mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 18mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 19mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 20potassium citrate
Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.
- 21supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 22mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 23mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 24mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 25mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
