Naturals Chicken & Rice Formula All Life Stages Dry Dog Food, 40-lb bag
Graded by The Sniff System
Diamond Naturals Chicken & Rice Formula is a dry dog food for all life stages, primarily featuring chicken.
This formula has a strong protein profile, with chicken as the main ingredient, offering high biological value. It also includes quality carbohydrate sources with fermentable fiber and good fat sources, like named fat with marine oil for EPA and DHA.
The main thing to note is that the AAFCO statement is ambiguous or incomplete, which means it's not as clear as it could be about its nutritional adequacy.
Good fit for dogs of all life stages. Less ideal if you prefer a product with a fully clear AAFCO statement.
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 plain beet pulp (prebiotic fiber) at position 10 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.

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.
- 2protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 3: major carbohydrate source.
- 4cracked pearled barley
Pre-cracked pearled barley for better digestibility. Same whole-grain story.
Position 4. Within the FDA's top-5 DCM-pattern threshold. Especially notable if multiple pulses stack here.
- 5grainwhite rice
Refined grain with the bran stripped off. Easy to digest, but not as nutrient-dense as brown rice.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6dried yeast
Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.
- 7fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8protein animalegg product
Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.
Position 8: supporting protein. Modest contribution to total protein weight.
- 9grain sorghum
Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.
Position 9: minor grain inclusion.
- 10dried 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 10: functional fiber for digestion or satiety.
- 11othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 12fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 12: trace fat. Below the level that materially shifts the fat profile.
- 13fatsalmon oil
Pure omega-3s. The thing skin-and-coat formulas are usually built around.
Position 13. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 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.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 19vegetablekale
Leafy green with antioxidants and fiber. Small dose in kibble, but it's not just for marketing.
- 20chia seed
Plant source of omega-3 and fiber. Like flaxseed, useful in trace amounts.
- 21vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 22fruitblueberries
Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.
- 23oranges
- 24grainquinoa
Pseudo-grain with a complete amino acid profile. Rare in dog food because it's expensive.
- 25supplementdried kelp
Natural source of iodine and trace minerals. A common premium-brand inclusion.
