How the conversion curve works

The first two years of a dog's life cover rapid development. After that, aging slows or accelerates depending on size. We blend published veterinary research for each bracket.

  • •Year 1 is about 15 human years.
  • •Year 2 adds roughly nine more.
  • •Each year after depends on weight class.
  • •Mixed breeds can choose the closest size.
