Dog Age Calculator
Get a more accurate human-age estimate for your dog using size-adjusted formulas — not the old "7 dog years per human year" rule, which significantly under-estimates puppies and over-ages middle-aged dogs.
Estimates use widely-accepted veterinary aging tables. Individual dogs vary — small breeds typically live 13–16 years, large breeds 8–12 years, and giant breeds 6–10. Mixed-breed dogs of average build tend to land in the medium bracket. For breed-specific aging, your vet will know the typical lifespan curve for your dog.
