The Comparison

Four 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.

Four Foods, One Method. Each row is one measure; the best figure in a row is marked.
01 Nulo Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish Swap Remove 02 Nulo FreeStyle Senior Trout & Sweet Potato Swap Remove 03 Stella & Chewy's Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb Swap Remove 04 Darwin's Natural Pet Products Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen Swap Remove
01 Protein, Dry Matter Higher Is Better 26-32% dm reads typical mainstream. 01 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish 38.9% 02 FreeStyle Senior Trout & Sweet Potato 33.3% 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb 46.7% 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen 57.7% 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 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish 29% 26.5% as fed Best in this row 02 FreeStyle Senior Trout & Sweet Potato 41% 37.0% as fed 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb 13% 0.0% as fed 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen 12% 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 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish 4 of 5 02 FreeStyle Senior Trout & Sweet Potato 3 of 5 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb 3 of 5 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen 5 of 5
04 Flagged Additives Level Lower Is Better Matched against the flag list. 01 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish None 02 FreeStyle Senior Trout & Sweet Potato None 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb None 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen None
05 Brand Recall History Lower Is Better Manufacturer, not recipe. 01 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish None Best in this row 02 FreeStyle Senior Trout & Sweet Potato None Best in this row 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb 2 None in the last 3 years 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen None Best in this row
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 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish 26.5% 02 FreeStyle Senior Trout & Sweet Potato 37.0% 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb 0.0% 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen 0.0%

Price / Lb Lowest Across Bag Sizes 01 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish $5.00 11 lb bag, Chewy 02 FreeStyle Senior Trout & Sweet Potato $3.33 24 lb bag, Hartville Hardware 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb -- No price on file. 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen -- No price on file.
Cost / 1,000 Kcal Lower Is Cheaper To Feed What the same amount of energy costs, so a denser food is not penalized for a higher price per pound. 01 Challenger Small Breed Organic Ancient Grains Haddock, Salmon & Acadian Redfish $3.04 02 FreeStyle Senior Trout & Sweet Potato $2.26 Best in this row 03 Stella & Chewy’s Wild Red : Whole Prey Chicken & Lamb -- No price on file. 04 Darwin’s Natural Pet Products BioLogics Raw Chicken for Healthy Dogs Grain-Free Frozen -- No price on file.

Add A Food

The comparison holds four foods. Use Swap on a column to put a different one in its place.

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.
