Tailyears, a Longevity Desk for Dogs

Field notes

Tailyears presents breed-level longevity information alongside calculators for lifespan, age, calories, and mixed-breed estimates by size. Its homepage says the material draws on studies involving more than 580,000 dogs and highlights a 12.5-year median from 584,734 UK dogs in 2024. It also surfaces concrete comparisons, including a cited 1.8-year lifetime difference for lean-fed Labradors and an 11.2-versus-12.8-year contrast between flat-faced and medium-muzzled breeds.
