According to new scientific research, that may not be quite right. The American Association for the Advancement of Science (AAAS) recently reported, "Dogs are much older than we think, and researchers devised a more accurate formula to calculate a dog's age based on the chemical changes in the DNA as organisms grow old."
Here's a new formula that, according to scientists, will be much more accurate than the 7 dog years = 1 human year we are all used to:
"The new formula, which applies to dogs older than one, says that a canine’s human age roughly equals 16 ln(dog age) + 31. (That’s the natural logarithm of the dog’s real age, multiplied by 16, with 31 added to the total.)"
If you can't figure that out, don't worry. The AAAS has created a handy calculator where you can just fill in your dog's age and find his or her age in human years. You'll find it half-way down on this page:
