How the Dog Age Calculator Works
Understanding the science behind converting dog years to human years.
Simple Method
The traditional 7:1 ratio multiplies your dog's age by 7. While easy to remember, this method doesn't account for the fact that dogs mature much faster in their first two years.
Scientific Method
Based on a 2019 UC San Diego study of DNA methylation, this logarithmic formula (16 ln(age) + 31) more accurately reflects how dogs age rapidly at first, then slow down.
Breed-Adjusted Method
The most accurate approach. This method uses size-specific multipliers because small dogs age differently than large dogs. Giant breeds age faster and have shorter lifespans.
