Dog Age Calculator — How Old Is Your Dog in Human Years?
Convert your dog's age to human years using the latest science-based formula. Accurate for all breed sizes.
About this agent
Our Dog Age Calculator uses the 2019 UC San Diego epigenetic research to convert dog years to human years. Unlike the old "multiply by 7" myth, our tool accounts for breed size (small, medium, large, giant) because large dogs age faster than small ones. Get instant results with life stage analysis and personalized care recommendations.
