Adult Urinary SO Aging 7+ Dry Dog Food, 26.5-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Adult Urinary SO Aging 7+ is a dry food for adult dogs 7 years and older, with chicken by-product meal as a primary protein source.
This formula includes quality fat sources like chicken fat and fish oil, which provides EPA and DHA. It also has egg product for diverse, bioavailable protein. The formula's adult maintenance claim is backed by AAFCO feeding trial substantiation.
The formula is plant-protein dominated, with brewers rice as the first ingredient. This means the protein content relies heavily on plant sources rather than animal-based ones.
Good fit for adult dogs 7 years and older needing urinary health support. Less ideal if you prefer formulas with animal protein as the primary source.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
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) . 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 57/100, this formula lands mid-pack. The lift comes from fat quality, worth 12 points to the final number: Quality fat sources: named fat with marine oil (EPA and DHA source). Where it lost ground: protein quality, costing 18 points. Plant-protein-dominated formula. brewers rice as the #1 ingredient. This formula sits 3.0 points below the B-tier line. The most direct lever is protein quality.

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 plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 4: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 5protein 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 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6brewers rice flour
- 7othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 8mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 9protein animalegg product
Processed whole eggs. Same nutritional profile as fresh eggs, just shelf-stable.
Position 9: supporting protein. Modest contribution to total protein weight.
- 10protein 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 10: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 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.
- 12fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 12: trace fiber inclusion.
- 13calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 14vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 14: trace fat. Below the level that materially shifts the fat profile.
- 15dried tomato pomace
The fiber-rich byproduct of tomato processing. Sometimes flagged unfairly. It's a real fiber source, not a filler shortcut.
Position 15: trace fiber inclusion.
- 16supplementl-arginine
- 17sodium bisulfate
- 18supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 19l-tyrosine
- 20monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 21fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 22mineralsodium tripolyphosphate
Preservative and texture agent in wet food. Functional at small doses, not a major concern, but some brands avoid it.
- 23supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 24supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 25supplementl-tryptophan
Essential amino acid. Sometimes added in calming or weight-management formulas.
