Adult Renal Support S Dry Dog Food, 17.6-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Adult Renal Support S is a dry food formulated for dogs needing renal support, with brewers rice as the first ingredient.
This formula uses quality carbohydrate sources that include fermentable fiber, which can be good for gut health. It also features 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 formula is plant-protein-dominated, with brewers rice as the first ingredient. Its protein and fat levels are quite low, which is likely by design for a renal support diet.
Good fit for dogs requiring renal support under veterinary guidance. Less ideal if your dog does not have specific kidney health needs.
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 49/100, landing in C-tier (acceptable-with-notes). The biggest contributor was carbohydrate quality (+16 points): Quality carbohydrate sources with fermentable fiber. A hard cap of 49 also applied because the guaranteed analysis falls below AAFCO's minimum nutrient profile. If a formula update that meets AAFCO minimums were on the label, the cap would lift and this formula could clear the B-band threshold (60).

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.
- 2graincorn
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 2: major carbohydrate source.
- 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.
- 4grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 6protein 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 6: supporting protein. Modest contribution to total protein weight.
- 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.
- 8protein 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 8: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 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.
- 11mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 12powdered psyllium seed husk
Position 12: trace fiber inclusion.
- 13sodium silico aluminate
Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.
- 14supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 15mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 16supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 17fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 18supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 19supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 20potassium citrate
Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.
- 21mineralmagnesium oxide
Inorganic magnesium. Functional at AAFCO doses, less efficiently absorbed than chelated forms.
- 22supplementl-tryptophan
Essential amino acid. Sometimes added in calming or weight-management formulas.
- 23marigold extract
- 24zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 25mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
