Adult Hydrolyzed Protein Small Breed Dry Dog Food, 8.8-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Adult Hydrolyzed Protein Small Breed is a dry food formulated for adult maintenance, featuring hydrolyzed soy protein.
This formula includes quality carbohydrate sources with fermentable fiber, which can be good for digestion. It also uses quality fat sources like chicken fat and fish oil, providing beneficial EPA and DHA. The product has AAFCO feeding trial substantiation for adult maintenance.
The formula is dominated by plant protein, with brewers rice as the first ingredient. This means the primary protein source isn't from animal meat.
Good fit for adult small breed dogs needing a hydrolyzed protein diet. Less ideal if you prefer a formula with animal protein as the primary ingredient.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for adult Cavalier King Charles Spaniels and similar moderately active toy breeds navigating diet-associated DCM concerns. Working in its favor: explicitly formulated for small-breed dogs. Chicken fat anchors position 3, with zero pulses in the top 15. The FDA's 2019 investigation update on diet-associated DCM included 13 reported cases in Cavalier King Charles Spaniels, making them one of the top 15 most frequently reported breeds at that time (FDA, 2019) .

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.
- 2hydrolyzed soy protein
- 3fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 3: primary fat source. Drives the formula's caloric density and omega-6 content.
- 4othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 5vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 5: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 6dried 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 6: functional fiber for digestion or satiety.
- 7sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 8calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 9mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 10mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 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.
- 12fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
Position 12: trace fiber inclusion.
- 13monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 14mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 15supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 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.
- 18supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 19gla safflower oil
- 20marigold extract
- 21mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 22zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 23mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 24manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 25mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
