True Adult Maintenance 21/12 Dry Dog Food, 50-lb bag
Graded by The Sniff System
Nutrena True Adult Maintenance 21/12 Dry Dog Food is a dry formula for adult dogs, primarily featuring chicken by-product meal.
This formula includes quality carbohydrate sources with fermentable fiber, which can be good for digestion. The AAFCO formulation for adult maintenance is inferred, though the verbatim statement isn't published by the retailer.
The formula is dominated by plant protein, with ground corn listed as the first ingredient. This indicates a lower overall protein quality compared to meat-first formulas.
Good fit for adult dogs. Less ideal if you prefer a meat-first formula or want higher quality protein sources.

Read why each ingredient is good or bad for dogs.
- 1grainground corn
Cracked whole corn. Fine in moderation, but its presence in the top few ingredients usually signals a lower-cost recipe.
Position 1 grain: primary carbohydrate base. This is a grain-inclusive formula with ground corn as the dominant carb.
- 2protein animalchicken by-product meal
Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
Position 3: major carbohydrate source.
- 4protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 4: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 5fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 5: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 6othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 7dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality. See why →
Position 7: functional fiber for digestion or satiety.
- 8monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 9mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 10vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 11vitaminniacin supplement
B vitamin (B3). Required in complete dog foods, added as a supplement to standardize the dose.

Vitamin A in stable, standardized form. Required for vision, immune function, and growth.
- 15vitaminvitamin d3 supplement
The active form of vitamin D dogs need. Required for calcium absorption and bone health.
- 16vitaminvitamin b12 supplement
Essential for red blood cell formation and neurological function. Plant ingredients lack B12, so it has to be added.

- 18vitaminbiotin
B vitamin that supports skin and coat health. Required for AAFCO-complete formulas.
- 19vitaminthiamine mononitrate
B vitamin (B1). Essential for nervous system function. Cooked-in vitamin loss is why thiamine is always added back.
- 20vitaminfolic acid
B vitamin (B9), essential for cell function. Standard in complete dog foods.
- 21mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 22yeast culture
Fermented yeast. Source of B vitamins and beta-glucans that some research suggests support immune function.
- 23mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 24mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 25mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
