Musher Yuka Honda dropped out of the Yukon Quest International Sled Dog race Friday, several hours before she was due to leave Dawson City on the second half of the race. When Honda arrived at the Dawson checkpoint, early Thursday morning, she was carrying a dead dog in her sled bag. A necropsy showed the dog had eaten several booties and had an enlarged heart. Ice thickness measurements, taken this week on the river, showed the ice was only six centimetres, or two inches, thick in some spots. Organizers said that was thick enough for the dog teams, but they didn't want to take a risk with the crowds that usually show up to see the frontrunners come in.
