The Comparison

Three Foods, One Method

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

Prices are the lowest per pound we found across bag sizes, from our latest checks. Stores change prices often.

Three Foods, One Method. Each row is one measure; the best figure in a row is marked.
01 Ultra Nutro Ultra Large Breed Adult Swap Remove 02 Ultra Nutro Ultra Large Breed Puppy Swap Remove 03 Darwin's Natural Pet Products Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen Swap Remove + Add A Food
01 Protein, Dry Matter Higher Is Better 26-32% dm reads typical mainstream. 01 Nutro Ultra Large Breed Adult 24.4% 02 Nutro Ultra Large Breed Puppy 28.9% 03 Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen 53.6% Best in this row
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 Nutro Ultra Large Breed Adult 50% 45.0% as fed 02 Nutro Ultra Large Breed Puppy 44% 40.0% as fed Best in this row 03 Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen 7% 0.0% 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 Nutro Ultra Large Breed Adult 2 of 5 02 Nutro Ultra Large Breed Puppy 2 of 5 03 Darwin’s Natural Pet Products Intelligent Design for Dogs Comprehensive Cancer Support Grain-Free Frozen 4 of 5

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.

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.
