Four Foods, One Method. Each row is one measure; the best figure in a row is marked.

01 Protein, Dry Matter Higher Is Better 26-32% dm reads typical mainstream.	01 Nature’s Logic Distinction Grain-Free Canine Red 33.0%	02 Nature’s Logic Distinction Canine Beef 35.2%	03 Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen 53.6% Best in this row	04 Lamb Feast Grain-Free 44.6%
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 Distinction Grain-Free Canine Red 39% 35.0% as fed	02 Nature’s Logic Distinction Canine Beef 36% 33.0% as fed	03 Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen 7% 0.0% as fed	04 Lamb Feast Grain-Free 9% 8.5% as fed Best in this row
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 Distinction Grain-Free Canine Red 3 of 5	02 Nature’s Logic Distinction Canine Beef 3 of 5	03 Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen 4 of 5	04 Lamb Feast Grain-Free 5 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.
