Why small dog age is different
Small dogs often have longer average lifespans than large dogs, so their adult and senior stages can arrive on a different timeline.
How to estimate small dog years
Use a size-aware calculator and choose small as the size group. The result gives a human-age style estimate.
What the estimate is for
Use it to understand life stage, adoption notes, and general care planning. It is not a veterinary diagnosis.
Quick tips
