Grain-Free Duck & Sweet Potato Recipe Dry Dog Food, 23.5-lb bag
Graded by The Sniff System
Health Extension Grain-Free Duck & Sweet Potato Recipe Dry Dog Food is a dry formula featuring duck and whitefish as its main protein sources.
This food has a strong protein profile, with duck as the first ingredient, offering high biological value. The formula pairs fresh duck with duck meal, a good sign for how the food is made. It also includes whitefish meal for diverse, high-quality protein.
The biggest concern is the lack of an AAFCO statement, which means its nutritional completeness is unverified. Also, there's high legume stacking with chickpeas, lentils, and peas all appearing in the top ingredients.
Good fit for dogs who do well on duck and sweet potato, especially if you prefer grain-free. Less ideal if AAFCO verification is a priority.

Sniff scored this formula 59/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+22.5 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).

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.
