Dallas Seavey wins record sixth Iditarod title but race marred by dog deaths

• 37-year-old wins the contest after nine days of racing
• Three dogs in other teams died during this year's contest

Alaska's annual Iditarod dog sled race ended with one of the biggest names in the sport coming from behind after a moose attack to win the grueling, days-long contest for an unprecedented sixth time.

But Dallas Seavey's record-setting win late on Tuesday was overshadowed by the deaths of three dogs in this year's endurance race across the Alaska wilderness, and renewed calls from an animal rights group to stop the race. A fourth dog, one of Seavey's, was severely injured in the moose attack.
