Natural Adult Chicken & Rice Formula Dry Dog Food, 40-lb bag
Graded by The Sniff System
Purina ONE Natural Adult Chicken & Rice Formula Dry Dog Food is a dry food built around chicken and rice, formulated for adult dogs.
This formula includes quality carbohydrate sources that provide fermentable fiber, which is good for gut health. It's also formulated for adult maintenance, meaning it's designed to meet the nutritional needs of adult dogs.
One thing to note is the absence of a declared omega-3 source like fish oil or salmon oil, which are often included for skin and coat health.
Good fit for adult dogs needing general maintenance. Less ideal if you're looking for a food with a clear omega-3 source.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult French Bulldogs and similar lower-energy companion breeds navigating a sensitive stomach. Chicken leads at position 1, with dried chicory root (prebiotic fiber) at position 13 on the deck. Frenchies have notoriously sensitive GI tracts plus a tendency toward obesity given their low activity needs. Limited-ingredient formulas with moderate calorie density tend to fit them well.

Sniff scored this formula 56/100, landing in C-tier (acceptable-with-notes). The biggest contributor was carbohydrate quality (+12 points): Quality carbohydrate sources with fermentable fiber. The biggest detractor was fat quality (-8 points): No declared omega-3 source. Fish oil, salmon oil, and algae oil all absent. The gap to B-tier is small (4.0 points). Addressing fat quality would likely close it.

Similar dog foods worth considering

Read why each ingredient is good or bad for dogs.
- 1protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 2: major carbohydrate source.
- 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.
Position 3: major carbohydrate source.
- 4grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5protein 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 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
Position 6: supporting grain. Smaller contribution to the carb deck.
- 7protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 7: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 8beef fat preserved with mixed-tocopherols
Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.
Position 8: supporting protein. Modest contribution to total protein weight.
- 9othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 10glycerin
Humectant used in soft-moist foods to keep them chewy. Safe in moderation but a signal of a processed semi-moist product.
- 11mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 12mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 13fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
Position 13: trace fiber inclusion.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 16vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
- 17dried peas
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 →
- 18vegetable juice
- 19mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 20mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 21mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 22mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 23mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
- 24mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 25supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
