01 Protein, Dry Matter Higher Is Better 26-32% dm reads typical mainstream.	01 Nature’s Logic Grain-Free Canine Duck & Salmon Meal Feast 36.3%	02 Nature’s Logic Distinction Canine Chicken 39.6%	03 Darwin’s Natural Pet Products Natural Selections Premium Beef Grain-Free Frozen 56.0%	04 Darwin’s Natural Pet Products Intelligent Design for Dogs Joint Support Grain-Free Frozen 56.5% Best in this row
02 Carbohydrate Load, Dry Matter Lower Is Better Estimated, 6% ash assumed. iEstimated, not measured. It is what is left of the guaranteed analysis once protein, fat, fiber and moisture are taken out, with ash assumed at 6%. That leftover is mostly starch but also carries sugars and the fiber a crude-fiber test misses, so read it as a close estimate rather than an exact figure. Measured as fed, the same basis as the bag.	01 Nature’s Logic Grain-Free Canine Duck & Salmon Meal Feast 35% 32.0% as fed	02 Nature’s Logic Distinction Canine Chicken 32% 29.0% as fed Best in this row	03 Darwin’s Natural Pet Products Natural Selections Premium Beef Grain-Free Frozen 12% 0.0% as fed	04 Darwin’s Natural Pet Products Intelligent Design for Dogs Joint Support Grain-Free Frozen 13% 0.0% as fed
03 Named Proteins In The First Five Count of named animal proteins. iThe count matches any named animal word in the opening five ingredients, so it also counts animal fats and flavourings as proteins. It is shown because it is one of the five measured lines, but it is too rough to call a winner on.	01 Nature’s Logic Grain-Free Canine Duck & Salmon Meal Feast 4 of 5	02 Nature’s Logic Distinction Canine Chicken 3 of 5	03 Darwin’s Natural Pet Products Natural Selections Premium Beef Grain-Free Frozen 3 of 5	04 Darwin’s Natural Pet Products Intelligent Design for Dogs Joint Support Grain-Free Frozen 3 of 5

Every figure here is the food's own. Protein and carbohydrate are converted to dry matter so foods of different moisture can be set beside each other; starch is estimated from the guaranteed analysis with ash assumed at 6.0%, and the recall record belongs to the manufacturer rather than to the recipe. Two rows are printed but never marked: the named-protein count, because the detection behind it is too rough to call a winner on, and calories, because neither more nor fewer is better without knowing the dog.
