How do you compare a dog’s age to that of a person? A popular method says you should multiply the dog’s age by 7 to compute how old Fido is in “human years.” But new research published Thursday in the Cell Systems journal debunks that method. And that’s because the scientists behind a new study say dogs and humans don’t age at the same rate. Researchers at the University of California San Diego School of Medicine have developed a new formula that takes into account that variance. Tracking molecular changes in the DNA of Labrador retrievers, and in particular “the changing patterns of methyl groups” in their genome, according to a release, the study shows how dogs age at a much faster rate than humans early in their lives, then slow down after reaching maturity.
