Adult Large Breed Dry Dog Food, 40-lb bag
Graded by The Sniff System
Eukanuba Adult Large Breed Dry Dog Food is a dry formula for adult large breed dogs, primarily featuring chicken and chicken by-product.
This formula offers reasonable protein quality, with chicken providing solid amino acid coverage. It also includes quality carbohydrate sources that provide fermentable fiber. A notable positive is that this food has AAFCO feeding trial substantiation for adult maintenance.
Nothing concerning in the deck.
Good fit for adult large breed dogs. Nothing serious working against it.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for adult Labrador Retrievers and similar active sporting breeds navigating weight management. Caloric density is not declared, with crude fiber at 11.5% (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) .

Sniff scored this formula 67/100, landing in B-tier territory. The biggest contributor was protein quality (+16 points): Reasonable protein quality. chicken delivers solid amino acid coverage. Also adding to the lift: carbohydrate quality (+13). Quality carbohydrate sources with fermentable fiber. The 8-point gap to A-tier sits mostly in protein quality (16 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
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2grainwheat
Whole wheat. Fine for most dogs, though a portion are sensitive. Not a quality concern, just a fit-for-your-dog question.
Position 2: major carbohydrate source.
- 3protein 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 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4graincorn
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 4: supporting grain. Smaller contribution to the carb deck.
- 5protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 5: 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.
- 6fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7brewers 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 7: supporting grain. Smaller contribution to the carb deck.
- 8protein animalpork meal
Pork cooked into a dry concentrate. Per pound, more protein than fresh pork.
Position 8: supporting protein. Modest contribution to total protein weight.
- 9ground grain sorghum
Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.
Position 9: minor grain inclusion.
- 10dried 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 10: functional fiber for digestion or satiety.
- 11othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 12monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 13mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 14marine microalgae oil
Plant-source omega-3 from algae. Useful especially in vegetarian or limited-fish formulas.
Position 14. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.
- 15preservative naturalrosemary extract
Natural preservative. Replaces synthetic ones like BHA and BHT.
Natural preservative. Methodologically preferred over synthetic alternatives.
- 16preserved with mixed tocopherols and citric acid
- 17supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 18mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 19fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 20mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 21zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 22mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 23manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
- 24mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 25mineralsodium 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 →
