Size Health Nutrition Puppy X-Small Dry Dog Food, 3-lb bag
Graded by The Sniff System
Royal Canin Size Health Nutrition Puppy X-Small Dry Dog Food is a dry food for puppies, with chicken by-product meal as its primary protein source.
This formula includes quality carbohydrate sources that provide fermentable fiber, which is good for gut health. It also features quality fat sources, including named fats and marine oil, a source of beneficial EPA and DHA. The food has AAFCO feeding trial substantiation for growth, which is a strong indicator of its nutritional adequacy for puppies.
The primary protein source, chicken by-product meal, contributes to lower protein quality, meaning it delivers limited bioavailable amino acids compared to other protein sources.
Good fit for X-small breed puppies. Less ideal if you prefer formulas with higher quality, more bioavailable protein sources.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Goldens appeared disproportionately in the FDA's DCM reports. Pulse-heavy grain-free formulas warrant extra caution; named animal protein with organ meat or marine sources is the safer fit. Strong fit for puppy Golden Retrievers and similar active sporting breeds navigating diet-associated DCM concerns. Chicken by-product meal anchors position 1, with zero pulses in the top 15.

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.
- 2brewers 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 2: major carbohydrate source.
- 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.
- 4fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 4: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 5protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 5: 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.
- 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.
- 7dried 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 7: functional fiber for digestion or satiety.
- 8othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 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.
- 10fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 10. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 11psyllium seed husk
Soluble fiber. Supports stool quality. The same fiber humans use for digestive regularity.
Position 11: trace fiber inclusion.
- 12sodium silico aluminate
Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 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.
- 17hydrolyzed yeast
Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.
- 18mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 19mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 20supplementyucca schidigera extract
Plant extract added to reduce stool odor. Functional, not nutritional. Fine in trace amounts.
- 21supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 22supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 23supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 24supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 25mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
