🔬 Science-Based Calculation
Our calculator uses the latest scientific formula: 16 × ln(dog age) + 31, adjusted for breed size. This is far more accurate than the old "multiply by 7" myth.
📊 Why Size Matters
Smaller dogs typically live longer than larger breeds. Giant breeds age faster and have shorter lifespans, while toy breeds can live well into their late teens.
