Dog Age Calculator
Dogs age at different rates depending on their size. Small breeds tend to live longer and age more slowly after the first two years, while large breeds age faster. This calculator uses a widely accepted table that accounts for the rapid development in the first two years (equivalent to ~24 human years) and the diverging rates by size thereafter.
