The premier annual event for dog breeders, dog lovers, and fans of photographs of puffed-out pooches has just come to an end. The Westminster Dog Show attracts some 2,500 dogs from around the nation to two days of pomp and preening before sold-out audiences at Madison Square Garden in New York City and a television audience around the world. Each dog's complete name includes the prefix "Ch" -- for champion, since each purebred entrant has already been a winner somewhere. The dogs are judged by groups, including Hound, Toy, Non-Sporting, Herding Sporting, Working, and Terrier. The top dog is selected in the final contest: "Best in Show.'' Six new breeds were included this year among the 179 eligible: Boykin spaniel, bluetick coonhound, redbone coonhound, cane corso, Leonberger, and Icelandic sheepdog. The show, which started in 1877, is second only to the Kentucky Derby as the longest continuously held sporting event in America. -- Lloyd Young ( 34 photos total
