Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Based on 3,363 OFA cardiac screenings, 1.0% of Saint Bernards had abnormal findings. Dilated cardiomyopathy and subaortic stenosis are noted heritable cardiac diseases in the breed (OFA) . Good fit for adult Saint Bernards navigating diet-associated DCM concerns. Beef anchors position 1, with zero pulses in the top 15, plus fish meal at position 10. What to watch: calorie density (496 kcal/cup) is rich for a lower-activity breed.

At 62/100, this formula lands in solid B territory. The lift comes from protein quality, worth 20 points to the final number: Reasonable protein quality. beef delivers solid amino acid coverage. Secondary contribution comes from fat quality (+12 points). Quality fat sources: named fat with marine oil (EPA and DHA source). The 13-point gap to the A-tier line is concentrated in ingredient-source specificity (3.5 of 12 possible) and protein quality (20 of 27 possible). Full ingredient-source specificity requires a named species (not a generic descriptor like "fish meal" or "animal fat") for every animal-source ingredient in the top 15; 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 animalbeef
Real meat. Dense in protein and iron. Some dogs are sensitive to it, but for most it's an excellent base.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainrice
Generic rice. Could be white or brown, the label doesn't say. Brown rice would be specified if it were.
Position 2: major carbohydrate source.
- 3protein animalpoultry by-product meal
Unnamed poultry. The mix can include any combination of chicken, turkey, or other birds, with no traceability. Named by-product meals are fine. This one isn't.
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4corn protein meal
Concentrated corn protein. Similar in role to corn gluten meal, pads the protein number on the label without matching meat amino acids.
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5grainwhole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6beef fat preserved with mixed-tocopherols
Real animal fat from a named species, with natural vitamin E doing the preservation. The clean version.
Position 6: supporting protein. Modest contribution to total protein weight.
- 7dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 7: supporting protein. Modest contribution to total protein weight.
- 8corn germ meal
Position 8: supporting grain. Smaller contribution to the carb deck.
- 9protein animalbison
Real meat, leaner than beef. Used as a novel protein, mostly in premium formulas.
Position 9: supporting protein. Modest contribution to total protein weight.
- 10protein animalfish meal
Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile. See why →
Position 10: supporting protein. Modest contribution to total protein weight.
- 11othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 12fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
Position 12. Moderate marine-oil inclusion. Supplements EPA/DHA without being the primary fat.
- 13soybean oil
Plant oil. High in omega-6, which is required but commonly oversupplied. Fine in moderation.
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.
- 15mono and dicalcium phosphate
Source of calcium and phosphorus. Standard inclusion in complete dog foods.
- 16mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 17mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 18mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 19mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 20mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 21mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 22mineralcalcium iodate
Source of iodine for thyroid function. Functional, required in complete formulas.
- 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 →
- 24supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 25mineralmagnesium sulfate
Source of magnesium, a required mineral. Standard inclusion in complete diets.
