Size Health Nutrition Small Adult Dry Dog Food, 14-lb bag
Graded by The Sniff System
Royal Canin Size Health Nutrition Small Adult Dry Dog Food is a dry formula for adult small dogs, primarily featuring chicken by-product meal.
This food uses quality carbohydrate sources that include fermentable fiber, which is good for digestion. It also has quality fat sources, like named chicken fat and fish oil, providing beneficial EPA and DHA. Plus, it's backed by AAFCO feeding trial substantiation for adult maintenance.
The main protein source, chicken by-product meal, offers limited bioavailable amino acids, which means the overall protein quality isn't as high as it could be. Nothing else concerning in the deck.
Good fit for small adult dogs. Less ideal if you prefer higher quality, more bioavailable protein sources.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Chicken by-product meal anchors position 1, with zero pulses in the top 15. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Sniff scored this formula 66/100, landing in B-tier territory. The biggest contributor was carbohydrate quality (+16 points): Quality carbohydrate sources with fermentable fiber. The biggest detractor was protein quality (-17 points): Low protein quality. chicken by-product meal delivers limited bioavailable amino acids. To reach A-tier, this formula would need to gain about 9 points, most likely through protein quality.

Read why each ingredient is good or bad for dogs.
- 1protein 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 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2graincorn
Whole corn is more nutritious than it gets credit for, with decent amino acids and steady carbs. The bigger concern is when corn dominates the top of the ingredient list at the expense of named meat.
Position 2: major carbohydrate source.
- 3brewers rice
Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version. See why →
Position 3: major carbohydrate source.
- 4grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 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.
- 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.
- 7corn 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 7: supporting grain. Smaller contribution to the carb deck.
- 8othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 9dried 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 9: functional fiber for digestion or satiety.
- 10vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 10: trace fat. Below the level that materially shifts the fat profile.
- 11fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 11. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
Position 15: trace fiber inclusion.
- 16mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 19preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 20preserved with mixed tocopherols and citric acid
- 21supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 22monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 23mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 24zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 25mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
