The Comparison

Two Foods, One Method

The same five measures, applied to each food from its own figures.

Two Foods, One Method. Each row is one measure; the best figure in a row is marked.
01 Castor & Pollux Pristine Grain-Free Grass-Fed Beef & Sweet Potato Swap Remove 02 Blue Life Protection Formula Large Breed Adult Lamb and Brown Rice Swap Remove + Add A Food + Add A Food
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 Life Protection Formula Large Breed Adult Lamb and Brown Rice 22.2%
02 Carbohydrate Load, Dry Matter Lower Is Better Estimated, 6% ash assumed. Estimated, 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 Life Protection Formula Large Breed Adult Lamb and Brown Rice 51% 46.0% as fed
03 Named Proteins In The First Five Count of named animal proteins. The 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 Life Protection Formula Large Breed Adult Lamb and Brown Rice 2 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 Life Protection Formula Large Breed Adult Lamb and Brown Rice None
05 Brand Recall History Lower Is Better Manufacturer, not recipe. 01 Pristine Grain-Free Grass-Fed Beef & Sweet Potato None Best in this row 02 Life Protection Formula Large Breed Adult Lamb and Brown Rice 5 4 in the last 3 years
Starch, As Fed Estimated, 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 31.5% 02 Life Protection Formula Large Breed Adult Lamb and Brown Rice 46.0%
Kcal / Cup 01 Pristine Grain-Free Grass-Fed Beef & Sweet Potato 393 02 Life Protection Formula Large Breed Adult Lamb and Brown Rice 365

Add A Food

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.
