We have always thought the 1 human year = 7 Dog years, turns out we were wrong!

Researchers at the University of California San Diego’s School of Medicine suggest a one-year-old puppy is actually about 30 in “human years”.

By the age of four, according to the research, a dog would be about 54 in “human years”, and by 14 they would be on a par with a human in their mid-70s.

So what IS the right calculation? human age = human_age = 16 ln(dog_age) + 31 but they still need to test other breeds.  Makes perfect sense right?

“Puppies age super quickly,” said Trey Ideker, the study’s senior author and a professor of genetics at the University of California, San Diego, School of Medicine. “By the time a dog is a year old, at a molecular level, he’s much more like a 30-year-old human. Retrospectively, we did know these things. It didn’t make any sense that the equivalent to a 7-year-old human would be able to have puppies.”
