New, More Accurate Dog Age Chart from Tufts University
April 20, 2012
It used to be that you multiplied your dog’s age by 7 and came out with a rough equivalent human age. Then this was refined by making the first year of your dog’s life equal 10 human years, the second 8 years and all the rest 7. This certainly seemed appropriate to me as the owner/guardian of two Labrador Retrievers.
At 2 years old they did seem like 18 year-old boys, not quite fully mature but certainly no longer “kids.”
Now the folks at Tufts University who publish the excellent Your Dog newsletter have added an additional factor: your dog’s weight, making this calculation even more accurate (see the chart below). Click image for larger size.
