📚 Formulas, Sources & Assumptions
Why two different numbers can both be "right" — and where ours come from.
Published by the American Kennel Club. Year 1 ≈ 15 human years, year 2 adds ~9, then aging slows and depends on breed size:
- Small (< 9 kg): +4 human years per dog year
- Medium (9–22 kg): +5 per year
- Large (> 22 kg): +6 per year
Based on DNA-methylation patterns shared between dogs and humans:
More accurate for adult dogs but derived from Labrador Retrievers, so it does not account for breed size differences.
All results are estimates for educational purposes only. Real biological age depends on breed, genetics, diet, weight, activity level and veterinary care. This tool is not a substitute for professional veterinary advice. For health concerns, please consult your veterinarian.
