Multifunction Renal Support + Advanced Mobility Support Dry Dog Food, 17.6-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Multifunction Renal Support + Advanced Mobility Support is a dry food formulated with chicken by-product meal as a primary protein.
This formula includes quality carbohydrate sources with fermentable fiber, which is good for gut health. It also uses quality fat sources, like named chicken fat and fish oil, providing EPA and DHA. The product has AAFCO feeding trial substantiation, which is a strong point for nutritional adequacy.
The formula is capped at a C-tier score due to its relatively low protein and fat levels on a dry matter basis. It's also a plant-protein-dominated formula, with brewers rice as the first ingredient.
Good fit for dogs needing specific renal and mobility support, likely under veterinary guidance. Less ideal if you're looking for a meat-first formula.
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 (+13 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.
- 4protein 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 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 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.
- 7fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 7. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 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.
- 9pork digest
Position 9: supporting protein. Modest contribution to total protein weight.
- 10vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 10: trace fat. Below the level that materially shifts the fat profile.
- 11mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 12mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14powdered psyllium seed husk
Position 14: trace fiber inclusion.
- 15sodium silico aluminate
Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.
- 16fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 19potassium citrate
Source of potassium. Sometimes added in urinary-support formulas to help manage urine pH.
- 20supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 21turmeric extract
- 22supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 23n-butyric acid
- 24mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 25mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
