Sled dogs trot through expanses of sparkling white snow, pulling a musher and energetically surging with the command, "Let's go!" From puppies to seasoned competitors, sled dogs partner with mushers in a passionate pursuit of a great racing tradition. The renowned and formidable Laconia World Championship Sled Dog Derby, the New England Sled Dog Club and famous drivers like Dr. Charles Belford—who came in fifth place at Laconia at the age of seventeen—helped solidify the fame of New England sled dog trails. Historian Bruce D. Heald celebrates the best of the sport in the region, from the feats of legendary Arthur Walden and his famous Chinook dogs to the Siberian huskies' contribution to the World War II effort. Join Heald as he charts the legacy of this remarkable sport.
