Dog age calculator

Pick your dog’s adult size, then the age in years and months. The tool converts that age with the AKC/AVMA medium-dog guideline: about 15 human years for year one, 9 more for year two, then about 5 human years for each year after. Size changes the life-stage label (when “senior” starts). Your pet’s name and age stay in this browser only.

No. The American Kennel Club calls the ×7 rule outdated. Dogs age fastest in the first two years, then slower. The published guideline on AKC’s dog-years page is closer to 15 + 9 + 5, not a flat seven.

AKC says aging after year two varies with age and size, but the calculator page we cite publishes the 15 / +9 / +5 guideline for a medium dog — not a public size×year number grid. This tool uses that guideline for the number, and uses size for the life-stage window (small dogs often called senior around 7; large dogs as early as 5–6).

It depends on size. AKC notes small dogs are often treated as senior around age 7, while large dogs may reach that stage as early as 5 or 6. The life-stage line in the result follows those windows. It is a planning cue, not a diagnosis — ask your vet about checks for your dog.

No. Dog & Cat Translator Pro is an entertainment app: you speak or tap, and it plays bark and meow sounds back. It does not decode a real bark, and it does not store the age you just calculated. Use the calculator for the math; use the app if you want a playful reply after you know the life stage.
