Size Health Nutrition Small Aging 12+ Dry Dog Food, 12-lb bag
Graded by The Sniff System
Royal Canin Size Health Nutrition Small Aging 12+ Dry Dog Food is a dry formula for small, aging dogs, primarily featuring chicken by-product.
This formula includes quality carbohydrate sources with fermentable fiber, which is good for digestion. It also uses quality fat sources like named fats and marine oil, providing EPA and DHA. You'll also find premium micronutrient forms, such as chelated minerals.
A significant watch item is the lack of an AAFCO statement, which means its nutritional completeness is unverified. Also, the formula is plant-protein dominated, with corn as the first ingredient.
Good fit for small, aging dogs. Less ideal if you prefer a verified AAFCO statement or animal-first protein sources.
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. Strong fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. At 308 kcal/cup this formula runs on the lean 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 53/100, this formula lands mid-pack. The lift comes from carbohydrate quality, worth 16 points to the final number: Quality carbohydrate sources with fermentable fiber. The ceiling on this score is 59, set because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). The cap isn't the binding constraint here. Protein quality would also need to improve to reach the next band.

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.
- 2grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
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.
- 4protein 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 4: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 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.
- 6corn 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 6: supporting grain. Smaller contribution to the carb deck.
- 7grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
Position 7: supporting grain. Smaller contribution to the carb deck.
- 8fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 8: trace fat. Below the level that materially shifts the fat profile.
- 9othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 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.
- 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.
- 12dried tomato pomace
The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.
Position 12: trace fiber inclusion.
- 13vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 13: trace fat. Below the level that materially shifts the fat profile.
- 14calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 15mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 16mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18supplementl-arginine
- 19mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 20fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 21supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 22mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 23l-tyrosine
- 24preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 25preserved with mixed tocopherols and citric acid
Showing first 25 of 42. Position 1-5 has the largest weight in the recipe.
