How Dog Years Work?

The old rule of "1 dog year = 7 human years" is a myth! Dogs mature extremely fast in their first two years then age more slowly relative to humans.

Developmental Milestones

  • Year 1: Comparable to a 15-year-old human (Social & growth peak).
  • Year 2: Comparable to a 24-year-old (Adulthood reached).
  • Year 3+: Size matters! Great Danes (Large) age 6 human years/year, while Chihuahuas (Small) grow by 4 years.
