Nothing concerning in the deck.
Good fit for adult dogs of any size. 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 Saint Bernards and similar lower-energy working breeds navigating diet-associated DCM concerns. Working in its favor: taurine listed as added ingredient. Lamb anchors position 1, with zero pulses in the top 15, plus salmon meal at position 8. What we'd flag: calorie density (442 kcal/cup) is rich for a lower-activity breed. As of the FDA's June 2019 update on diet-associated DCM, the Saint Bernard was one of the most reported breeds, with 10 cases submitted to the agency (FDA, 2019) .

Read why each ingredient is good or bad for dogs.
- 1protein animallamb
Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalchicken meal
Chicken with the water cooked out. Per pound, packs more protein than fresh chicken. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 3: major carbohydrate source.
- 4grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5oat meal
Alternate spelling of oatmeal. Gentle whole grain, steady carb energy, soluble fiber.
- 6protein animallamb meal
Lamb cooked down to a dry concentrate. Per pound, more protein than fresh lamb. See why →
Position 6: supporting protein. Modest contribution to total protein weight.
- 7fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 7: trace fat. Below the level that materially shifts the fat profile.
- 8protein animalsalmon meal
Salmon cooked into a dry concentrate. Carries both protein and natural omega-3s in one ingredient. See why →
Position 8: supporting protein. Modest contribution to total protein weight.
- 9grainquinoa
Pseudo-grain with a complete amino acid profile. Rare in dog food because it's expensive.
Position 9: minor grain inclusion.
- 10othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12dried yeast
Natural source of B vitamins and trace minerals. Adds a savory flavor that dogs respond well to.
- 13fibermiscanthus grass
Perennial grass used as a fiber source. Replaces cellulose in some recipes. Functional but unremarkable.
Position 13: trace fiber inclusion.
- 14mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 15mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 16dehydrated alfalfa meal
Dried alfalfa. Fiber and trace minerals. Not exciting but it's a real plant ingredient.
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18fruitapples
Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.
- 19vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
- 20mineraliron amino acid complex
Iron bound to amino acids for better absorption. Premium form versus inorganic iron sulfate.
- 21mineralzinc amino acid complex
Zinc bound to amino acids for better absorption. Same idea as zinc proteinate, the premium form of the mineral.
- 22mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 23mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 24mineralmanganese amino acid complex
Manganese bound to amino acids for better absorption. The chelated form most premium brands use.
- 25mineralcopper amino acid complex
Copper bound to amino acids for better absorption. Premium form versus copper sulfate.
