On the AAHA canine age chart that weight falls in 51–90 lb or 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 66–78 human years. That is 16 human years older than the up-to-20-lb line on the same chart (56).

The listed lifespan is 8–10 years, so a 10-year-old is near the end of the typical range.
