A seven-year-old border collie named Kelso was the winner Saturday night (February 8th) of the Westminster Kennel Club's new agility competition, beating out 225 other dogs on a course that included running through tunnels and over ramps and weaving through poles. A husky mix named Roo! was another winner, making it to the final five to earn a prize for the top mixed-breed -- dubbed "all-American dog" -- at the nation's most prestigious show for the first time since the late 1800s. There were 63 different breeds represented in the agility competition and about 16 competitor were mixes.
