About this tool

The ×7 rule came from a rough average and falls apart at both ends: a one-year-old dog is not a seven-year-old child, it is closer to a teenager, and large breeds age faster than small ones after the first two years. The commonly cited veterinary approximation gives the first year about fifteen human years, the second about nine more, then roughly four to six per year depending on size. This tool applies that curve by weight band and reports the life stage — puppy, adult, senior, geriatric — which is what actually changes how you feed and exercise the animal. It is an estimate, not a diagnosis.
