Canine Care Nutrition Large Digestive Care Dry Dog Food, 30-lb bag
Graded by The Sniff System
Royal Canin Canine Care Nutrition Large Digestive Care Dry Dog Food is a dry formula with chicken by-product meal as its main protein source.
This formula uses quality carbohydrate sources with fermentable fiber, which is good for digestive health. It also includes quality fat sources like named fat and marine oil, providing beneficial EPA and DHA. Plus, the formula has undergone AAFCO feeding trials for substantiation.
Nothing concerning in the deck.
Good fit for large dogs who need support for their digestive health. Nothing serious working against it.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. Working in its favor: L-carnitine listed (supports fat metabolism). At 343 kcal/cup this formula runs on the moderate side, with crude fiber at 4.6% (above the catalog median, supports satiety). 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. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

Solid grade. 68/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Carbohydrate quality did the heavy lifting (+15 points): Quality carbohydrate sources with fermentable fiber. The supporting beat: fat quality (+12 points). Quality fat sources: named fat with marine oil (EPA and DHA source). What's keeping it out of A-tier: protein quality (13.5 of 27 possible). Full protein quality requires named-species named-cut proteins in the top of the deck (e.g., "deboned chicken" rather than "chicken meal" or "poultry meal").

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.
- 2brewers 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 2: major carbohydrate source.
- 3grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 3: major carbohydrate source.
- 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.
- 5fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 5: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 6othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 7brewers rice flour
- 8dried 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 8: functional fiber for digestion or satiety.
- 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.
- 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.
- 11fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 11. Trace inclusion. Below the level associated with the FDA's DCM-pattern concerns.
- 12sodium silico aluminate
Same role as sodium aluminosilicate. Anti-caking agent at trace inclusion.
- 13vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 13: trace fat. Below the level that materially shifts the fat profile.
- 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.
- 17psyllium seed husk
Soluble fiber. Supports stool quality. The same fiber humans use for digestive regularity.
- 18hydrolyzed yeast
Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.
- 19supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 20supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 21supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 22supplementglucosamine hydrochloride
Joint-support compound. Most useful in larger doses for older dogs. The kibble dose is real but modest.
- 23mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 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.
