Dog Age Calculator

How old is your best friend in human years?

Dog Age Calculator gives you a simple estimate using your dog's age and adult size. Choose their age in years and months, find their breed, and see an illustrated human-age result.

MADE FOR EVERYDAY CURIOSITY

WORKS OFFLINE
The calculator, breed list, font and illustrations are included in the app. No account is needed. There are no ads, subscriptions or in-app purchases.

YOUR INPUTS STAY ON YOUR DEVICE
Your chosen age, breed, size and result are processed locally. The calculator has no analytics or tracking and does not upload your inputs or keep a saved calculation history. Read the privacy policy inside the app, or open the public policy in your browser.

A LITTLE AGE SCIENCE
Dogs grow quickly in their first two years, and adult size affects the estimate after that. The app explains its simplified calculation so you can understand the result. Breed suggests a typical adult size, and you can adjust it to fit your dog.

Results are approximate comparisons for curiosity and general information. Dogs age differently, and a veterinarian can assess your dog's individual health and needs. The dog artwork is decorative and does not represent every breed.

A little older. A lot more loved.
