Adult Urinary SO Loaf Pate Wet Dog Food, 13.5-oz can, case of 12
Graded by The Sniff System
Royal Canin Veterinary Diet Adult Urinary SO Loaf Pate Wet Dog Food is a wet food that features chicken liver as a primary protein source.
This formula includes quality fat sources, like marine oil, which provides beneficial EPA and DHA. It also features organ meat, like chicken liver, for diverse, highly bioavailable protein. The food has AAFCO feeding trial substantiation for adult maintenance.
The formula contains carrageenan, a seaweed-derived thickener some studies link to gastrointestinal inflammation. There's also guar gum, an emulsifier with emerging microbiome data, but no direct canine clinical evidence.
Good fit for adult dogs. Less ideal if your dog has a sensitive stomach or you prefer to avoid thickeners like carrageenan.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for active large sporting breeds, including the Golden Retriever, navigating diet-associated DCM concerns. Chicken liver anchors position 2, with zero pulses in the top 15, plus chicken liver at position 2 (a natural taurine precursor). 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 fat quality (+12 points): Quality fat sources: named fat with marine oil (EPA and DHA source). The biggest detractor was controversial-ingredient penalty (-5 points): Contains carrageenan. Plausible rodent colitis mechanism, no direct canine clinical evidence at food-grade levels. Concern elevated for dogs with IBD. To reach B-tier, this formula would need to gain about 11 points, most likely through controversial-ingredient penalty.

Controversial ingredients · 1
- carrageenanSeaweed-derived thickener; some studies link it to gastrointestinal inflammation. Most common in wet foods but appears in some kibble gravies.
Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →
Wet and fresh foods contain more water than kibble (typically 65-78%). On a dry-matter basis, this food's protein content is roughly 21%, comparable to premium kibble (typically 30-45% DMB protein).
Read why each ingredient is good or bad for dogs.
- 1water sufficient for processing
The regulatory phrase for cooking water in wet food. Has no nutritional implication, just labeling formality.
- 2protein animalchicken liver
Organ meat. Dense in protein, iron, vitamin A, and the B vitamins. Among the most nutrient-rich ingredients a dog can eat.
Position 2. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.
- 3chicken by-products
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4pork by-products
Generic pork organs and tissue without species-specific traceability. Named by-products are more transparent.
Position 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5corn grits
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6corn starch
Position 6: supporting grain. Smaller contribution to the carb deck.
- 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.
- 8fiberpowdered cellulose
Plant fiber, often from wood pulp. Cheap bulk filler. Not harmful, but a tell that the recipe is reaching for inexpensive bulk.
Position 8: functional fiber for digestion or satiety.
- 9mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 10monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 11othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 12fiberguar gum
Thickener common in wet food. Emerging research on emulsifiers and the gut microbiome, but no smoking gun in dogs yet. See why →
Position 12: trace fiber inclusion.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14carob bean gum
- 15fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 15. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.
- 16supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 17calcium sulfate
Source of calcium. Functional, required for AAFCO-complete formulas.
- 18othercarrageenan Flagged
Seaweed-derived thickener. Some lab studies suggest gut inflammation, but the evidence in pets is mixed. See why →
- 19supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 20supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 21zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 22mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 23mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 24mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 25manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
