Formule
Formula: Logarithmic: Human age = 16 × ln(dog_age) + 31. Simple: Year 1-2 = 12 human years each, then +5 per year.
Questions fréquemment posées
Why not just multiply by 7?
The old "multiply by 7" rule is inaccurate. Dogs mature rapidly in early years. A 1-year-old dog is closer to a 30-year-old human. The logarithmic formula better matches actual aging.
How was the logarithmic formula developed?
Researchers at UC San Diego studied DNA methylation patterns in Labrador Retrievers and found that aging follows a logarithmic curve matching human epigenetic changes.
Does dog breed affect aging?
Yes. Smaller breeds tend to live longer (12-16 years) while giant breeds may only live 6-10 years. This calculator provides a general estimate.
