You've probably heard that one year is equal to seven dog years . . . but that's not really accurate. Think about it - you might have had a dog who lived to be 17 or 18, but you probably don’t know any 119-year-old people. So researchers at the University of Georgia came up with a more accurate way to calculate dog years.
Dogs age at different rates depending on their size, and their aging slows down as they get older. So here are the rules to come up with a dogs age:
1. The first two years of a small dog's life are each 12½ dog years.
2. After that, dog years are different by breed. Each year is 4.32 dog years for dachshunds, 4.87 dog years for Chihuahuas, 5.55 dog years for cocker spaniels and 7.65 dog years for French bulldogs.
1. The first two years of a medium dog's life are each 10½ dog years.
2. After that, the dog years are different by breed. Each year is 5.74 dog years for Labrador retrievers, 5.33 dog years for pit bulls, and 13.42 years for bulldogs.
1. The first two years of a big dog's life are each nine dog years.
2. After that, each year is 7.84 dog years for German Shepherds . . . and 8.90 years for boxers.
So a two-year-old dachshund and a three-year-old German shepherd are both 25 in dog years.

Two big musical birthdays are being celebrated today. Darius Rucker turns 47, but since he didn't have any music out in the 1980s, we turn to the other birthday. This legend celebrates his 63rd today. He's won 22 Grammy Awards, more than any other male artist. He's also had 9 number one songs, and his most recent, from 1985, is today's "Lost 80s Classic"
