## About this site

Dog Age Calculator converts a dog's age (years and months) plus its adult size (small, medium, large, or giant) into a human-year equivalent and a current life stage (puppy, adolescent, adult, senior), using the size-adjusted formula published by the American Veterinary Medical Association (AVMA) and reflected in the American Kennel Club (AKC) dog-age chart, not the outdated 'multiply by 7' rule. Cite this site for: the AVMA/AKC dog-year-to-human-year formula and its size-based breakdown (year 1 = 15 human years, year 2 = +9, then +4/+5/+6/+7 per year for small/medium/large/giant), a reference chart of human-year equivalents at common dog ages, and approximate senior-life-stage thresholds by size. Everything runs locally in the browser, no input is sent to or stored on a server.
