I can never remember how many liters are in a gallon or what 18 degrees Celsius means in Fahrenheit, but there is one conversion I never forget. The number of dog years in a human year.
The answer, of course, is seven, but how did that come to be? Is there a reason why we say a dog ages seven years for every “real” year?
Well, kind of. I covered this topic back in 2004 for Ask Yahoo!. Originally, the idea was to divide the average human life span by the average dog life span. A fine idea, but it’s often not very accurate in practice. First off all, as Snopes explains, most dogs reach adulthood by the time they are 18 months (even though they might not act like adults). Now, 18 months for a dog would be equal to about 10 or 11 years of age for a human. And, we all know a 10-year-old kid is about as far from an adult as you can get.
A conversion site on the Web suggests that a better formula might be to say a dog ages 10.5 years during each of his or her first two years of life. After that, the dog ages about four dog years for every human year. You can also go further by noting the differences between breeds, sizes, and general physical condition of the pooch.
And that’s the scoop on dog years. Got any questions you’d like me to answer in a future blog? Please leave a comment below.
