The idea that dogs age seven years for every human year is a myth, scientists have claimed.
University of California researchers said they have also found puppies are middle-aged by the time they are two, although dogs tend to age more slowly than humans in later life.
By the time they get to three – and are possibly still getting away with things due to being considered young – dogs are closer in age to a 50-year-old human, according to the university’s research.
Overall, the average 12-year lifespan of a Labrador lined up with the average worldwide lifespan of humans, which is about 70 years.
The new formula for a dog’s ages based on the study requires a little more math than multiplying by seven. You multiply the natural logarithm of a dog’s age by 16, then add 31 [human_age = 16ln(dog_age) + 31].
