Limited Ingredient Reserve Duck & Brown Rice Recipe Dry Dog Food, 22-lb bag
Graded by The Sniff System
Natural Balance Limited Ingredient Reserve Duck & Brown Rice Recipe Dry Dog Food is a dry food featuring duck as its main protein source.
This formula offers good protein quality, with duck providing solid amino acid coverage. It also uses quality carbohydrate sources that include declared fiber. The recipe pairs fresh duck with duck meal, which is a strong way to build a dry food.
The biggest watch item here is the lack of an AAFCO statement, which means the nutritional completeness of this food is unverified. This absence capped the overall score.
Good fit for dogs who do well on a duck and rice limited ingredient diet. Less ideal if you prioritize verified nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for active large sporting breeds, including the Golden Retriever, navigating diet-associated DCM concerns. Duck anchors position 1, with zero pulses in the top 15, plus added taurine at position 14. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Sniff scored this formula 59/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+16.5 points): Reasonable protein quality. duck delivers solid amino acid coverage. 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).
