How to use the dog age calculator
Enter your dog’s age in years and select a size category to see a broad human-equivalent estimate.
How the calculation works
There is no single scientific human-age equivalent for every dog. Breed, size and health affect ageing; the familiar seven-years-per-dog-year shortcut is overly simplistic.
Check your inputs carefully: an incorrect date can change a result. Dates and times are entered using your device settings, and no account is needed. For formal, legal, medical or financial purposes, verify the applicable local rules and official records.
Frequently asked questions
Is this a veterinary diagnosis?
No. It is a rough educational comparison and not a substitute for veterinary advice.
Should I use this for medical or scientific decisions?
No. Fun comparisons are approximations and should not replace expert information.
Are the dates I enter uploaded?
No. AgeGlide calculates your results in your browser. Entered dates are not sent to our server for processing.
