The classic '15 for year one, 9 for year two, 5 per year after' rule, done precisely.
Real canine aging depends heavily on breed and size — small breeds tend to live longer and age more slowly in their later years than large breeds, which mature faster but age faster too. This calculator uses the widely cited simple version, not a size-adjusted one.
Dogs reach physical and reproductive maturity within about 1-2 years, which is why the early aging rate is so much faster than a human's — a 1-year-old dog is roughly equivalent to a 15-year-old human, not a toddler.

Human-equivalent age: 39 years
A 5-year-old dog is roughly equivalent to a 39-year-old human, using the classic 15/9/5 rule — actual aging varies a lot by breed and size, with larger breeds aging faster in later years.
