How is this calculated?
1
Dogs: Size matters — large dogs age faster than small dogs. A 10-year-old Great Dane is older in human terms than a 10-year-old Chihuahua.
2
Cats: The first 2 years age rapidly — year 1 equals ~15 human years. After that, each cat year equals roughly 4 human years.

This calculator uses the updated American Veterinary Medical Association guidelines — more accurate than the old “multiply by 7” rule.
