Adult Hydrolyzed Protein HP Dry Dog Food, 25.3-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Adult Hydrolyzed Protein HP Dry Dog Food is a dry formula for adult dogs, featuring hydrolyzed soy protein.
This formula includes quality carbohydrate sources that provide fermentable fiber, which can be good for gut health. It also uses quality fat sources like 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 is a plant-protein-dominated formula, with brewers rice as the first ingredient. This means the primary protein source is not animal-based.
Good fit for adult dogs requiring a hydrolyzed protein diet for sensitivities. Less ideal if you prefer a meat-first ingredient list.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Golden Retrievers and similar active sporting breeds navigating diet-associated DCM concerns. Chicken fat anchors position 3, with zero pulses in the top 15. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Sniff scored this formula 56/100, landing in C-tier (acceptable-with-notes). The biggest contributor was carbohydrate quality (+13 points): Quality carbohydrate sources with fermentable fiber. The biggest detractor was protein quality (-18 points): Plant-protein-dominated formula. brewers rice as the #1 ingredient. The gap to B-tier is small (4.0 points). Addressing protein quality would likely close it.

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.
- 6vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 8monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 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.
- 10mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 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.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 15supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 16supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 17gla safflower oil
- 18marigold extract
- 19mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 20zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 21mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 22manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 23mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 24mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 25mineralsodium 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 →
