How the Breed Health Score works

Each breed gets one 0 to 100 score (higher is healthier), combining longevity (65%), conformation risk (20%) and hereditary disease burden (15%). Median lifespan is the real figure from a peer-reviewed study of 584,734 dogs; we make it sortable, comparable and cited. Read the methodology →
