Hydrolyzed Protein Dry Puppy Dog Food, 22-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Hydrolyzed Protein Dry Puppy Dog Food is a dry formula for puppies, featuring hydrolyzed soy protein.
This formula includes quality carbohydrate sources with fermentable fiber, which can be good for digestion. It also has quality fat sources like named chicken fat and fish oil, providing beneficial EPA and DHA. Plus, it's backed by AAFCO feeding trial data for growth.
The main thing to note is that this is a plant-protein-dominated formula, with brewers rice as the first ingredient. There are no other flagged ingredients to watch out for.
Good fit for puppies who need a hydrolyzed protein diet. Less ideal if you prefer a meat-first formula.
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. Good fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Chicken fat anchors position 3, with zero pulses in the top 15.

At 54/100, this formula lands mid-pack. The lift comes from carbohydrate quality, worth 13 points to the final number: Quality carbohydrate sources with fermentable fiber. Where it lost ground: protein quality, costing 18 points. Plant-protein-dominated formula. brewers rice as the #1 ingredient. The path to B-tier is about 6 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.
- 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.
- 5dried 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 5: functional fiber for digestion or satiety.
- 6monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 7vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 9fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 9. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 10sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 11fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
Position 11: trace fiber inclusion.
- 12mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 13supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 14mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 15supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 16supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 17l-threonine
Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.
- 18mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 19zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 20mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 21manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 22mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 23mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 24mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 25mineralcopper proteinate
Copper bound to protein for better absorption. Common in better-formulated diets.
