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.
Hill’s Prescription Diet k/d + Mobility Kidney + Joint Care Chicken Flavor is missing protein, dry matter and carbohydrate load, so it is judged on fewer measures than the others here.

|---|---|---|---|---|
| 01 Protein, Dry Matter Higher Is Better 26-32% dm reads typical mainstream. | 01 Hill’s Prescription Diet k/d + Mobility Kidney + Joint Care Chicken Flavor -- Not enough data on file. | 02 Hill’s Prescription Diet Gastrointestinal Biome Digestive/Fiber Care with Chicken 18.9% | 03 PureVita Puppy Lamb & Pumpkin Entree Grain-Free 30.0% 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 Hill’s Prescription Diet k/d + Mobility Kidney + Joint Care Chicken Flavor -- Needs protein, fat, fiber and moisture. | 02 Hill’s Prescription Diet Gastrointestinal Biome Digestive/Fiber Care with Chicken 41% 37.0% as fed | 03 PureVita Puppy Lamb & Pumpkin Entree Grain-Free 40% 36.0% as fed Best in this row | |
| 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 Hill’s Prescription Diet k/d + Mobility Kidney + Joint Care Chicken Flavor 3 of 5 | 02 Hill’s Prescription Diet Gastrointestinal Biome Digestive/Fiber Care with Chicken 1 of 5 | 03 PureVita Puppy Lamb & Pumpkin Entree Grain-Free 2 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%.

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.
