WHITEHORSE, Yukon  Newton Marshall thought he was in trouble upon receiving a call that began the Jamaicans odyssey as a dog musher.

In 2005, Marshall was working as a horseback-riding guide for Chukka Caribbean Adventures when a phone call unwittingly changed his life.

One day, they called me when I was up in the mountains and told me ?Newton, you have to stop work immediately and I said Why I didn?t do anything wrong, Marshall said Wednesday from Hans Gatt?s kennel a half-hour south of Whitehorse.
