How does one steer a dog sled like at the Iditarod?

"gee" is right. "haw" is left. "on by" is dont stop, dog keep goin by. "whoa" is stop. there are others plus Im sure each person communicates with their dogs with their own commands. praise for the dogs is also very important.pairing the dogs together to get good chemistry is important also. one female dog can keep an over-anxious male dog in line and pulling how he should.
