Website overview
About PuppyCalc
PuppyCalc is a free browser-based dog age calculator. Visitors enter a dog age and choose a small, medium or large breed-size group to see an estimated human-age comparison and life-stage label. The page also provides a 1–20 year size-based chart and explains why a flat seven-to-one rule is not a reliable model. Results are common educational estimates rather than exact medical data, and owners are directed to a veterinarian for an individual health assessment.
