the dogs
the perfect sled dog is the Alaskan Husk with its thick fur and strong legs . Each dog must be healthy so vets examine them care fully before the race begins . These dogs were originally used to tranport goods and mail all over Alaska. However when people started using snowmobiles travelling by sled became less popular . This traditional form of transport seemed to be dying out until the Iditarod Race was started in 1973.
