Legume-Free Chicken-Free Duck with Butternut Squash Dry Dog Food, 30-lb bag
Graded by The Sniff System
American Natural Premium Legume-Free Chicken-Free Duck with Butternut Squash is a dry dog food featuring duck and turkey as its main protein sources.
This formula has a strong protein profile, with duck as a primary ingredient, which means good biological value for your dog. It also includes quality carbohydrate sources with fermentable fiber and named fat sources like marine oil, providing beneficial EPA and DHA.
The main thing to note is that this product lacks an AAFCO statement, which means its nutritional completeness is unverified. It also contains MSG, often from yeast extract, which can obscure the true formulation.
Good fit for dogs needing a chicken-free or legume-free diet. Less ideal if you prioritize a verified AAFCO statement for nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
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. Good fit for active large sporting breeds like Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. At 384 kcal/cup this formula runs on the moderate side, with crude fiber at 5% (above the catalog median, supports satiety). 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) .

At 59/100, this formula lands mid-pack. The lift comes from protein quality, worth 20 points to the final number: Strong protein profile with duck as the primary ingredient, delivering high biological value. The ceiling on this score is 59, set because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). The fix path: the brand publishing the AAFCO statement. That would lift the cap and put this formula above the B-band line at 60.

Read why each ingredient is good or bad for dogs.
- 1protein animalduck
Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalturkey
Real meat. Lean protein, good amino acid profile, often well-tolerated by dogs sensitive to chicken.
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3protein animalturkey meal
Turkey with the water cooked out. Per pound, packs more protein than fresh turkey. See why →
Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 4oat flour
- 5grainbrown rice
Whole grain that's easy to digest. Steady carb energy plus a little fiber.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6protein animalpork meal
Pork cooked into a dry concentrate. Per pound, more protein than fresh pork.
Position 6: supporting protein. Modest contribution to total protein weight.
- 7ground grain sorghum
Same as sorghum. Whole grain with a low glycemic index. Gluten-free, well-tolerated.
Position 7: supporting grain. Smaller contribution to the carb deck.
- 8vegetablevegetable
Unnamed vegetable. No way to know what species. Named vegetables are far more transparent.
Position 8: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 9grainpearled barley
Barley with the outer hull removed. Easy to digest, steady carb release.
Position 9: minor grain inclusion.
- 10vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
Position 10: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 11pork fat
Real animal fat from a named species. Clean energy source.
Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 12othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 13brewer's dried yeast
- 14dried 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 14: trace fiber inclusion.
- 15fatsunflower oil
Common plant oil. Useful in moderation for omega-6, though too much skews the omega ratio against the dog's favor.
Position 15: trace fat. Below the level that materially shifts the fat profile.
- 16fatmenhaden fish oil
Omega-3 from menhaden, a small oily fish. Same skin and coat support as salmon oil.
- 17mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 18mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 19mineralzinc sulfate
Inorganic zinc. Effective at AAFCO doses but less well-absorbed than chelated forms like zinc proteinate.
- 20mineraliron proteinate
Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.
- 21mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 22mineralcopper proteinate
Copper bound to protein for better absorption. Common in better-formulated diets.
- 23mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 24mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 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 →
