Direct answer: a dog’s first year is roughly 15 human years, the second adds about 9, and each year after adds about 5. So a 2-year-old dog is ~24 in human years, a 5-year-old ~39. Enter your dog’s age below. This is an estimate — smaller breeds age more slowly in later years, larger breeds faster.

Questions

Dog Age Calculator — FAQ

How old is my dog in human years?
Roughly: 1 dog year ≈ 15 human years, 2 ≈ 24, then about +5 per year. A 7-year-old dog is ~49. It’s an estimate that varies by breed size.
Is the ×7 rule accurate?
No — the old ‘multiply by 7’ rule is a myth. Dogs mature fast early then slow down, which the life-stage model above reflects more closely.
Do big and small dogs age the same?
No. Small breeds tend to live longer and age more slowly in later years; large breeds age faster. Treat the number as a guide.
Is this veterinary advice?
No — it’s a general estimate. For health and life-stage care, consult your veterinarian.
