What breed is most likely to win a dog show

Through the 134th Westminster Show (February 2010), Best in Show has been won by the Terrier group 45 out of the 103 times that the prize has been awarded since 1907,[10] more than twice as many wins as any other group. The single breed that has won the most is the Wire Fox Terrier, which has won 15 times. Two of the most popular dog breeds in the United States—the Labrador Retriever and Golden Retriever—have never won Best in Show.[11] The dogs are marked for Best in Breed and then proceed to compete in Best in Group, and finally in the grand prize competition of Best in Show

The Wire Fox Terrier is to date, the winningest breed at the Westminster Show with 15 total wins. Terriers in general have won over 40% of the Best in Show competitions across the long history of the show.
