Scottish Terrier 'Top Dog' at Westminster, Protesters Rush Ring

Sadie the Scottish Terrier is the first dog to ever win the dog world's 'Triple Crown'The roar coming from Madison Square Garden Tuesday night wasn't for the Knicks storming down the court, but for a single Scottish Terrier crowned Best In Show.

As the packed arena anxiously awaited, Best in Show judge Elliot B. Weiss chose Sadie as champion of the 134th Westminster Kennel Club Dog Show.

"A dog of this quality comes along once in a decade," said Weiss.

Sadie also won at the National Dog Show and the AKC/Eukanuba National Championship last year, and was heavily favored to win Westminster. The Scottish Terrier is the first dog to ever win all three events in the dog world's "Triple Crown."

Of nearly 2,500 dogs and 173 breeds, Sadie trotted away with the $50,000 cash prize, beating out six other group winners who fur-ociously competed.

The group winners of the 2010 show were:

Sporting- Brittany

Working- Doberman Pinscher

Terrier- Scottish Terrier

Toy- Toy Poodle

Non-Sporting- French Bulldog

Hound- Whippet

Herding- Puli

But, all dogs competing are champions, needing to have won prior American Kennel Club competitions to enter Westminster.

Half way through the Best In Show judging, two protesters rushed the ring holding signs reading "Mutts Rule" and "Breeders are Killing Shelter Dog's Chances." Spectators were confused and booed the women as security escorted them out of the ring. The judging continued as additional security guarded the ring entrances. Police said the women were charged with criminal trespass.

Sadie now joins the ranks of other Best In Show dogs, like 2009's winner Stump, the oldest winner of the title, a 15-inch Beagle in 2008, and English Springer Spaniel in 2007.

Historically, terriers, particularly fox terriers have out-numbered other breeds in being crowned best. Sadie is now the eighth Scottish Terrier to have won Best In Show, the last being in 1995. Although America's "favorite" dog, a Golden Retriever has never been crowned champion at Westminster.

The Westminster Kennel Club Dog Show was established in 1877 and is the second longest continuously held sporting event in the U.S., behind the Kentucky Derby.
