DogYearsPricing
DogYears is free. Every calculator, chart and converter on this site works without an account, a paywall, or a “trial”. That is the whole deal for now.

Pro is a teaser, not a product: coming soon, not billed. Nothing on this page charges you anything, and no payment details are collected.
Why free? Age conversion is a thirty-second question, and the honest answer should never sit behind a checkout. If a Pro tier launches, it will be for people keeping records across several pets — the calculators themselves stay free either way.
