On the AAHA canine age chart that weight falls in over 90 lb. The calculator on this page is the PawCalculator dog age calculator: 16 × ln(age) + 31, with the senior threshold set from the giant 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 78 human years for males (over 90 lb) and 66–78 for females (51–90 lb or over 90 lb). That is 22 human years older than the up-to-20-lb line on the same chart (56).
The listed lifespan is 9–10 years, so a 10-year-old is near the end of the typical range.
