Canine Care Nutrition Medium Digestive Care Dry Dog Food, 30-lb bag
Graded by The Sniff System
Royal Canin Canine Care Nutrition Medium Digestive Care is a dry dog food with chicken by-product meal as its primary protein source.
This formula includes quality carbohydrate sources that provide fermentable fiber, which is good for digestion. It also features quality fat sources, like named chicken fat and fish oil, which supplies beneficial EPA and DHA.
The primary protein source is chicken by-product meal, which our methodology flags for delivering limited bioavailable amino acids, indicating lower protein quality.
Good fit for medium-sized dogs needing digestive support. Less ideal if you prioritize higher quality, more bioavailable protein sources.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. Good fit for active large sporting breeds, including the Labrador Retriever, navigating weight management. At 321 kcal/cup this formula runs on the lean side. According to the Association for Pet Obesity Prevention's 2023 survey, 59% of dogs in the United States were classified as overweight or obese by their veterinary healthcare professional, representing an estimated 55 million dogs (APOP, 2023) .

At 63/100, this formula lands in solid B territory. The lift comes from carbohydrate quality, worth 15 points to the final number: Quality carbohydrate sources with fermentable fiber. Where it lost ground: protein quality, costing 17.5 points. Low protein quality. chicken by-product meal delivers limited bioavailable amino acids. The path to A-tier is about 12 points; protein quality is the structural lever.

Read why each ingredient is good or bad for dogs.
- 1protein 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 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 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.
- 3brewers 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 3: major carbohydrate source.
- 4fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 4: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 5grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 6: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 7brewers rice flour
- 8othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 9dried 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 9: functional fiber for digestion or satiety.
- 10fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 10. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 11vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 12. Trace inclusion. Below the level associated with the FDA's DCM-pattern concerns.
- 13sodium silico aluminate
Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 15mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 16mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 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.
- 19hydrolyzed yeast
Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.
- 20supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 21mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 22mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 23zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 24mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 25manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
