| Starch, as fedEstimated, 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.

Brand figures are averages over every kibble recipe we review from that brand, with the lowest and highest recipe underneath. Freeze-dried, frozen, wet food and toppers are left out so the numbers compare like with like, and so are prescription diets, which are fed for a medical condition on a vet's advice. Everything is as fed, the way the bag prints it; the switch above the table shows protein and fat on a dry matter basis instead, which takes the water out so foods of different moisture compare evenly. Why we use as fed.
The Closest Matching Recipes
Brand averages hide the recipe you would actually buy. These are the pairs that come closest on protein, fat and starch, preferring recipes built on the same main protein, which is where a like-for-like choice gets made.

Which Fits Your Dog
- For an active or working dog, or one that needs to hold muscle, Blue Buffalo puts more protein in each bowl.
- For a dog that gains weight easily, Hill's is less calorie dense, so a normal-looking portion carries fewer calories.
- If you are cutting back on starch, Blue Buffalo starts lower.
- The brands overlap more than the averages suggest: Blue Buffalo runs from 18% to 46% protein as fed and Hill's from 16% to 30%, so the right recipe matters more than the name on the bag.
Recall History
