That husky of ours would come in the house to visit us for about a half-hour and then want to go outside. I remember several times looking out the window at 40 below to see her sleeping on top of her insulated dog house. She could come in just by asking or she could go into her dog house, but she apparently wasn't cold. She lived to be two days past her 16th birthday, by the way. Her last winter, we forced her to come into the house at nights and she was miserable. She didn't like the warmth. She'd go down to the basement and lay on the cold floor, panting.

This idea that dog sledding is cruel is a myth perpetrated by people who have never been around huskies. It's what they do. They have hundreds of generations of breeding that makes them who they are. The musher may be organizing them to run in the same direction for a goal, but he/she is not "forcing" these dogs to run. It's what they love to do.
