Size Health Nutrition Small Indoor Adult Dry Dog Food, 2.5-lb bag
Graded by The Sniff System
Royal Canin Size Health Nutrition Small Indoor Adult 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. It also uses quality fat sources, like named chicken fat and fish oil, providing beneficial EPA and DHA. Plus, it has AAFCO feeding trial substantiation for adult maintenance.
The main thing to watch is that this formula is plant-protein-dominated, with brewers rice as the first ingredient. Nothing else concerning in the deck.
Good fit for small indoor adult dogs. Less ideal if you prefer a formula with a meat-first protein source.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. Good fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. At 354 kcal/cup this formula runs on the moderate side. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

At 63/100, this formula lands in solid B territory. The lift comes from carbohydrate quality, worth 15 points to the final number: Quality carbohydrate sources with fermentable fiber. Where it lost ground: protein quality, costing 19.5 points. Plant-protein-dominated formula. brewers rice 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.
- 1brewers 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 1 grain: primary carbohydrate base. This is a grain-inclusive formula with brewers rice 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.
- 3graincorn
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 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.
- 6protein 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 6: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 7othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 8dried 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 8: functional fiber for digestion or satiety.
- 9vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 9: trace fat. Below the level that materially shifts the fat profile.
- 10fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 10. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 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.
- 12sodium silico aluminate
Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 15l-tyrosine
- 16calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 17mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 18supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 19supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 20fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 21mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 22supplementl-arginine
- 23supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 24mineralmagnesium oxide
Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.
- 25mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
