person of good fortune, usually one considered so by others.
This appears to be a propitious dog reference, though it is sometimes used to imply that the good fortune may not have been deserved or acquired through devious means. And, given that a dog's chance is a rather slim one, perhaps a lucky dog is one who really has beaten the odds. In analyzing the 1995 deal for broadcasting Major League Baseball games, Richard Sandomir of the New York Times (Apr 18, 2008) makes this explicit: “If you are Major League Baseball, you are one lucky dog. You have done nothing right on the business side for years, but Fox, CBS, ABC/ESPN and Turner have all been competing for pieces of your future.�?
