ANCHORAGE, Alaska — A 1-year-old Australian shepherd took an epic trek across 150 miles (241 kilometers) of frozen Bering Sea ice that included being bitten by a seal or polar bear before he was safely returned to his home in Alaska.

Mandy Iworrigan, Nanuq's owner who lives in Gambell, Alaska, and her family were visiting Savoogna, another St. Lawrence Island community in the Bering Strait, last month when Nanuq disappeared with their other family dog, Starlight, the Anchorage Daily News reported.
