Bayfield, Wisconsin - Curled up snugly in the snow, Rosy, Kathy, Milly and Bobby blinked dreamily into the winter sun near Lake Superior in the US state of Wisconsin. The biting cold was dry, so it was not too unpleasant. In fact, at about minus 20 degrees centigrade, it was just right for them and 30 other Siberian huskies.
"This weather is ideal for my dogs," remarked John Thiel, who runs a dog-sled tour company near the northern Wisconsin town of Bayfield.
"They feel best and run fastest at these temperatures."
