For those who think shooting these dogs is remotely humane, may I suggest you read how the lives of 100 sled dogs were killed due to a slump in tourism in British Columbia...real humane!

This article proves my point...that it took repeated shots to take their target down and even that wasn't always enough and so other measures were taken to finish the killings...btw, is British Columbia impoverished?
