About 64 human years by the AVMA medium-dog guideline, or 68 by the UCSD genetic formula. A 10-year-old dog is about 64 human years (AVMA medium dog) — a senior for medium and large breeds.
The AVMA curve is based on life-stage milestones (puppy, adult, senior); the UCSD formula is fitted to DNA methylation clocks. They agree on the early years and diverge for seniors — both are shown so you can judge.
Yes. Small dogs live longer and age more slowly after year two (about +4 human years per dog year); giant breeds age faster (+6 or more). This calculator uses the medium-dog +5 curve.
