Gear Score Methodology
PetPal Gear Score
Best Sensitive-Stomach Foods and Diet-Transition Tools for Dogs and Cats (2026)
Editorial synthesis of Tufts Petfoodology, AAHA Nutritional Assessment Guidelines, the Merck Veterinary Manual cutaneous food allergy chapter, AAFCO labeling rules, FDA pet-food guidance, and manufacturer documentation — no first-hand product testing. This guide does not diagnose food allergies and does not replace a veterinary workup.
PetPal Gear Score = (Expert Consensus × 0.35) + (Real-Household Sensitivity Fit × 0.25) + (Veterinary Alignment × 0.20) + (Value × 0.20)Factor breakdown
Expert Consensus
35%Synthesized from Tufts Petfoodology, AAHA Nutritional Assessment Guidelines, the Merck Veterinary Manual cutaneous food allergy chapter, AAFCO labeling guidance, FDA pet-food guidance, and manufacturer documentation. The PetPal Gear Score is a composite of expert opinion — PetPalHQ does not run a testing lab and does not diagnose food allergies.
Real-Household Sensitivity Fit
25%How clearly the food matches a defined household scenario (mild digestive sensitivity, ingredient-deck simplification, vet-led elimination trial) rather than generic 'sensitive stomach' marketing.
Veterinary Alignment
20%How well the product aligns with the Merck Veterinary Manual's framing of dietary elimination trials as the reference standard, Tufts Petfoodology's trial-duration recommendations, and AAHA's nutritional assessment framework.
Value
20%Price relative to the editorial price tier, balanced against actual diagnostic and management value — retail LIDs are cheaper but solve a smaller piece of the problem than vet-led hydrolyzed trials.
