Scientists have developed a new formula to calculate to calculate your dog’s age!

Scientists have come up with a new, more accurate way to compare your dog’s age to human years based on changes in their DNA called “DNA methylation”.  As reported on the Science Magazine website, the new formula applies to dogs over age one.  The new formula is  16ln(dog age) + 31.   For you math whizzes, that’s the NATURAL LOGARITHM of the dog’s real age, multiplied by 16, with 31 added to the total.  Or, simply follow this link to the full article and it will automatically calculate your dog’s age when you input their current age!
