| 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. Protein and fat are on a dry matter basis, starch and calories 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, Wellness 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, Wellness starts lower.
- If your vet has suggested a grain-inclusive diet, Hill's has more of those recipes to choose from.
- The brands overlap more than the averages suggest: Wellness runs from 23% to 42% protein and Hill's from 17% to 32%, so the right recipe matters more than the name on the bag.
Recall History
FDA recall notices from the last five years that name the brand or its maker. Older notices sit in each brand's archive below: still on the record, but not counted, since a recall that old says more about how a company used to run than how it runs now.
