About Pet Age Calculator.

The old "1 dog year = 7 human years" rule is inaccurate. Modern veterinary science shows dogs age faster in early years, with size affecting their aging rate. Small dogs tend to live longer than large dogs. For cats, the first year equals ~15 human years, the second adds ~9, then each year is ~4 human years.
