An Australian shepherd dog who took an epic 150 mile journey across sea ice, during which he was bitten by a seal or polar bear has returned to his family's home in Alaska.
The year-old pup, Nanuq, disappeared while Mandy Iworrigan, from Gambell, Alaska, and her family were visiting Savoonga, another St Lawrence Island community in the Bering Strait.
Nanuq disappeared with other family dog, Starlight, who ended up turning up just a few weeks later.
