The winner of the Terrier Group has been selected for Best in Show at Westminster 45 times. The Wire Fox Terrier leads the pack with 13 wins, followed by the Scottish Terrier with 9. The Airedale, Smooth Fox and Sealyham Terriers tied with 4 victories. Sadly, two of the most popular dog breeds in the United States — the Labrador Retriever and the Golden Retriever — have never won Best in Show. That's OK, guys. You're still America's favorites!
