More: "O'Riley" was the lead dog of "Jim's Team", our All Rescue Sled Dog Team. He is 13 now, and retired from the team. He was the best lead dog ever! Once he came unhooked from the gang line, and he still ran lead in front of the team the whole course. These huskies are true "outdoor dogs" . Bred to survive the elements, a heroic dash of dog teams in 1925 helped save residents of Nome Alaska from diphtheria by delivering lifesaving serum a thousand miles. These dogs love to run, and be part of a team.
