How Pet Age Calculator is Calculated
This calculator uses the formula: Dog: varies by size | Cat: 15 (yr1) + 9 (yr2) + 4/yr after. Where Small dog life: ~16 yrs ; Medium: ~13 yrs ; Large: ~10 yrs ; Cat: ~15 yrs. Larger dogs age faster. The old '7 years per human year' rule is inaccurate. All calculations run entirely in your browser — no data is transmitted to any server.
