What the label cannot tell you

A label shows minimums and maximums, not how much your pet will eat, how well a food is digested, or whether it suits a health condition. Brand-level medians blur very different recipes together. Ask your veterinarian before changing a pet's diet. Dry matter values use each label's own moisture maximum, and calorie rows use the calories per kg recorded from each label.
