What better way to spend Valentine’s Day? The Westminster Kennel Club show kicks off Monday night, with judging in the hound, toy, nonsporting, and herding groups. Nearly 2,600 dogs will show at Madison Square Garden for the event. Oddsmakers have a smooth fox terrier named Dodger as the favorite, followed by a Pekingese, a boxer, and an Irish setter. A new breed this year is the Leonberger, a combination of a Saint Bernard, a Newfoundland, and a Great Pyrenees.
