ANCHORAGE, Alaska (AP) — The board for Alaska's most famous sled dog race will kick mushers out of the competition if one of their dogs dies while on the trail, race officials said. The Iditarod Trail Committee board debated and eventually approved the change among others at its meeting in Anchorage on Friday. Reaching a compromise, the board of directors added the caveat that if a dog's death "was caused solely by unforeseeable forces," then a musher may be allowed to stay in the Iditarod Trail Sled Dog Race.
