The Iditarod dog sled race in Alaska is mourning the death of two dogs.
One dog belonging to the team of musher Seth Barnes died near a checkpoint along the grueling race. Officials are investigating the cause of the death. Before that, a dog which had been dropped by musher Scott Smith's team because of an injury, died while it was being flown to another checkpoint. An exam suggests that it died from hypothermia.
The deaths are sitting well with animal rights activists. PETA says 30 dogs have died during the race since 2004 and are calling for a permanent end to event which has been around since 1973. (Alaska Dispatch News)
