On the AAHA canine age chart that weight falls in 51–90 lb. The calculator on this page is the PawCalculator dog age calculator: 16 × ln(age) + 31, with the senior threshold set from the large size class. The table is the AAHA chart, which changes with weight class, so the two numbers answer different questions.

Reading the numbers

At 10 years the chart reads 66 human years for males (51–90 lb) and 60–66 for females (21–50 lb or 51–90 lb). That is 10 human years older than the up-to-20-lb line on the same chart (56).

The listed lifespan is 12–15 years, so a 10-year-old is still inside the published range.
