New Way to Calculate Dog Years
New Scientific Way to Calculate “Dog Years”
We’ve always heard converting your dog’s age to “dog-years” was just multiplying your dog’s age in “human years” by seven, right?
Scientists say they have now come up with a more accurate way to determine how old your dog is. Researchers at the University of California, San Diego, examined dog DNA to see how quickly dogs age, and found that this is the correct formula for calculating dog years:
Take the natural logarithm of a dog’s age, multiply it by 16, and then add 31.
In plain English, that means you grab a scientific calculator, enter your dog’s age, then press ‘in’.
Multiply the result by 16, then add 31.
Using that formula, a two-year old dog is 42, a five-year-old dog is almost 57, and a ten-year-old is 67.8.

This method might not be completely accurate for every breed, but it is believed to be a much more accurate way of determining your dog’s ‘human’ age than the old, unscientific “7-years” rule.
