Hill's Science Diet vs Pedigree

Hill's Science Diet (veterinarian-recommended premium kibble with the deepest prescription-diet portfolio on the market) and Pedigree (low-priced kibble from a maker that meets 4 of WSAVA's 5 questions, with a flagship label that says "formulated to meet" AAFCO profiles) compared head-to-head on WSAVA manufacturer-quality criteria, AAFCO substantiation, monthly cost, and which dog each is best for in 2026. Hill's Science Diet meets 5 of 5 WSAVA criteria. Pedigree is roughly 57% less than Hill's Science Diet.

The verdict

Hill's Science Diet meets all 5 WSAVA questions at $55-85/month. Pedigree meets 4 at $15-45/month. The one-point gap comes from feeding trials, which Hill's backs with 50+ years of data from an owned research facility. Pedigree's flagship label says "formulated to meet" AAFCO profiles instead. At both ends of the two ranges, Hill's costs $40 more each month.

Hill's is the pick if you want continuity into Hill's Prescription Diet and a maker with a long clinical record. Pedigree fits a healthy adult dog on a tight budget whose owner is comfortable with a formulation-based label and the credentialed nutrition staff at Mars Petcare. For any dog with a condition, let your veterinarian choose, not the price tag.
