Wholesome Grain-Free Duck & Cassava Recipe Dry Dog Food, 20-lb bag
Graded by The Sniff System
Lotus Wholesome Grain-Free Duck & Cassava Recipe Dry Dog Food is a grain-free dry food with duck as its primary protein.
This food features a strong protein profile with duck as the primary ingredient, offering high biological value. It also includes quality fat sources like named duck fat and herring meal, which provides marine oil for EPA and DHA. The combination of fresh duck and duck meal is a good sign for its extrusion architecture.
The main thing to watch out for is the lack of an AAFCO statement, which means its nutritional completeness is unverified. This absence capped its overall score.
Good fit for dogs needing a grain-free diet with duck as the primary protein. Less ideal if you require an AAFCO statement for nutritional completeness.
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. Caloric density is not declared, with crude fiber at 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 59/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+23 points): Strong protein profile with duck as the primary ingredient, delivering high biological value. A hard cap of 59 also applied 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). If the brand publishing the AAFCO statement were on the label, the cap would lift and this formula could clear the B-band threshold (60).
Strong protein profile with duck as the primary ingredient, delivering high biological value.
Quality fat sources: named fat with marine oil (EPA and DHA source).
Named fresh meat paired with same-species meal, a strong extrusion architecture.
No AAFCO statement. Nutritional completeness unverified.
- Lowest fat quality in Lotus's lineup (12/16)

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 animalduck meal
Duck cooked into a dry concentrate. Per pound, more protein than fresh duck.
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3legumepeas
Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
Position 3. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.
- 4cassava flour
- 5vegetablepotato
Standard white potato. Steady carb source, common starch in grain-free recipes.
Position 5: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.
- 6protein animalherring meal
Concentrated herring with the water removed. Carries protein and omega-3s in one ingredient.
Position 6: supporting protein. Modest contribution to total protein weight.
- 7fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 7. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 8dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 8: supporting protein. Modest contribution to total protein weight.
- 9brewers dried yeast
Yeast left over from brewing. Rich in B vitamins and amino acids. A traditional and well-tolerated inclusion.
- 10vegetablesweet potato
Complex carb with fiber and beta-carotene. Gentle on the stomach.
Position 10: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 11fatground flaxseed
Cracked flaxseed for better digestibility. Same plant omega-3s as whole flaxseed, just easier for the dog to extract.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12duck fat
Position 12: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14fatsalmon oil
Pure omega-3s. The thing skin-and-coat formulas are usually built around.
Position 14. Trace marine oil. Contributes some omega-3 but well below the level that drives EPA/DHA totals.
- 15olive oil
Position 15: trace fat. Below the level that materially shifts the fat profile.
- 16carrot
Real vegetable. Fiber, beta-carotene, antioxidants. Same as carrots, sometimes singular on labels.
- 17apple
Real fruit, some fiber and antioxidants. The amount in kibble is too small to matter much.
- 18mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 19mineraliron proteinate
Iron bound to protein for better absorption. The premium form versus inorganic iron sulfate.
- 20calcium propionate
- 21mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 22vitaminvitamin e supplement
Required nutrient and a natural antioxidant. Often pulls double duty as a preservative.
- 23fruitblueberries
Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.
- 24vegetablepumpkin
Soluble fiber that supports stool quality. Mild and well-tolerated.
- 25vegetablespinach
Leafy green. Some iron, vitamin K, and fiber. The dose in kibble is small but it's real food.
