Size Health Nutrition Small Adult 8+ Dry Dog Food, 13-lb bag
Graded by The Sniff System
Royal Canin Size Health Nutrition Small Adult 8+ Dry Dog Food is a dry kibble for adult dogs 8 years and older, with chicken by-product meal as a primary protein source.
This formula includes quality carbohydrate sources that provide fermentable fiber, which is good for gut health. It also features quality fats like chicken fat and fish oil, a source of EPA and DHA. The food has AAFCO feeding trial substantiation for adult maintenance.
The main thing to watch out for is that this formula is plant-protein-dominated, with corn listed as the very first ingredient. This means a significant portion of the protein comes from plant sources rather than animal.
Good fit for small adult dogs 8 years and older who benefit from fermentable fiber and quality fats. Less ideal if you prefer a primary animal protein source.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
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) . 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 2, with zero pulses in the top 15.

At 63/100, this formula lands in solid B territory. The lift comes from carbohydrate quality, worth 16 points to the final number: Quality carbohydrate sources with fermentable fiber. Where it lost ground: protein quality, costing 20 points. Plant-protein-dominated formula. corn as the #1 ingredient. The path to A-tier is about 12 points; protein quality is the structural lever.

Read why each ingredient is good or bad for dogs.
- 1graincorn
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 1 grain: primary carbohydrate base. This is a grain-inclusive formula with 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.
- 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.
- 4corn 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 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.
- 6grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 6: supporting grain. Smaller contribution to the carb deck.
- 7brewers rice flour
- 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.
- 10protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
Position 10: moderate plant-protein boost. Less likely to materially shift the protein 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.
- 12mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 13mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 14fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
Position 14: trace fiber inclusion.
- 15mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 16supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 17supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 18mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 19supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 20preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 21preserved with mixed tocopherols and citric acid
- 22mineralmagnesium oxide
Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.
- 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.
