I suppose each sport has a Dark Side. I experienced the Dark Side of Dog Mushing, first hand today. I met a musher disposing of some of the dogs culled from his kennel along the road leading to my house. Disgusting. I asked him how many he culled. He said it takes about 30 dogs to get a good one. The ravens were pleased though. I don't think I had the stomach for it, even in my younger years. Do other mushers have a remedy for this, or is it just a common way of developing a kennel of winners?
