Adult Gastrointestinal Low Fat Dry Dog Food, 28.6-lb bag
Graded by The Sniff System
Royal Canin Veterinary Diet Adult Gastrointestinal Low Fat Dry Dog Food is a dry formula with chicken by-product meal as a primary protein source, designed for adult dogs.
This formula includes quality carbohydrate sources that also provide fermentable fiber, which can be good for gut health. It also uses quality fat sources, like chicken fat, and includes marine oil for EPA and DHA. The product has AAFCO feeding trial substantiation for adult maintenance.
One thing to note is that this formula is plant-protein-dominated, with brewers rice listed as the first ingredient. This means the primary protein source isn't meat-based.
Good fit for adult dogs who need a low-fat diet and benefit from fermentable fiber. Less ideal if you prefer a meat-first recipe.
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. At 247 kcal/cup this formula runs on the lean side, with crude fiber at 4.8% (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) .

Middle-of-pack grade. 59/100 (C) 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. What we'd flag for vet discussion: protein quality (-19 points). Plant-protein-dominated formula. brewers rice as the #1 ingredient. B-tier is 1.0 points away. Improving protein quality is the most direct route.

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.
- 2protein 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 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
Position 3: major carbohydrate source.
- 4othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 5pork digest
Position 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 6fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 6. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 7dried 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 7: functional fiber for digestion or satiety.
- 8fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 8: trace fat. Below the level that materially shifts the fat profile.
- 9monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 10mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 11mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 12mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 13powdered psyllium seed husk
Position 13: trace fiber inclusion.
- 14sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 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.
- 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.
- 18preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
- 19preserved with mixed tocopherols and citric acid
- 20hydrolyzed yeast
Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.
- 21supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 22marigold extract
- 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.
