A Scottish terrier is America's new top dog.

Sadie the Scottie walked off with the title Tuesday night by winning best in show at the Westminster Kennel Club.

The show for purebred dogs at Madison Square Garden in New York was briefly interrupted in the final minutes by two protesters. Two women calmly walked into the center ring and held up signs saying "Breeders Kill" and "Mutts Rule." They were led away by security without incident.

Sadie was the huge favorite, and a crowd of about 15,000 saw the 4-year-old earn her 112th best in show ribbon.

Sadie beat out six other dogs in the final ring. Also in contention were a whippet, a French bulldog, a toy poodle, a brittany, a puli and a Doberman pinscher.
