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 Pristine Grain-Free Grass-Fed Beef & Sweet Potato 36.0% Best in this row	02 Hill’s Prescription Diet Derm Defense Environmental Sensitivities Chicken Flavor -- Not enough data on file.	03 Hill’s Science Diet Adult 7+ Chicken Meal, Barley & Rice 17.2%	04 Hill’s Science Diet Adult 1-6 Chicken & Barley 22.2%
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 Pristine Grain-Free Grass-Fed Beef & Sweet Potato 35% 31.5% as fed Best in this row	02 Hill’s Prescription Diet Derm Defense Environmental Sensitivities Chicken Flavor -- Needs protein, fat, fiber and moisture.	03 Hill’s Science Diet Adult 7+ Chicken Meal, Barley & Rice 60% 54.0% as fed	04 Hill’s Science Diet Adult 1-6 Chicken & Barley 54% 48.5% 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 Pristine Grain-Free Grass-Fed Beef & Sweet Potato 3 of 5	02 Hill’s Prescription Diet Derm Defense Environmental Sensitivities Chicken Flavor 1 of 5	03 Hill’s Science Diet Adult 7+ Chicken Meal, Barley & Rice 1 of 5	04 Hill’s Science Diet Adult 1-6 Chicken & Barley 1 of 5
04 Flagged Additives Level Lower Is Better Matched against the flag list.	01 Pristine Grain-Free Grass-Fed Beef & Sweet Potato None	02 Hill’s Prescription Diet Derm Defense Environmental Sensitivities Chicken Flavor None	03 Hill’s Science Diet Adult 7+ Chicken Meal, Barley & Rice None	04 Hill’s Science Diet Adult 1-6 Chicken & Barley None
05 Brand Recall History Level Lower Is Better Manufacturer, not recipe.	01 Pristine Grain-Free Grass-Fed Beef & Sweet Potato None	02 Hill’s Prescription Diet Derm Defense Environmental Sensitivities Chicken Flavor None	03 Hill’s Science Diet Adult 7+ Chicken Meal, Barley & Rice None	04 Hill’s Science Diet Adult 1-6 Chicken & Barley None
Starch, As Fed 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.

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.
