In the Bible, Caleb, along with Jacob, was one of the only two Isrealites who left Egypt with Moses and lived long enough to enter the Promised Land. While it's literal meaning comes from the word "dog," it's often translated into "faithful" and "loyal"—two qualities commonly used to describe man's best friend. After having its heyday in the 1800s, Caleb fell off the charts and reappeared in the 1960s and has been rising in popularity ever since.
