Ove Karlsen, who works as an electrician on North Sea oil platforms, posted the video last last week on YouTube and was surprised to find himself hit by a rush of interview requests from the international media.
"I was suddenly called by the Daily Mail, among others. I do not remember what all the newspapers were called, but they were all very interested in my story and wanted to share the video I have on my youtube account," a somewhat shell-shocked Karlsen told Norway's Dagbladet newspaper.
The video, shot last winter, shows Karlsen edge himself out over the ice, wearing a wetsuit he had put on especially for the rescue attempt, slip into the water to greet the suffering animal, and then coax it to a rope he had laid over the ice.
"Some people say they have cried while watching it because they were so touched," Karlsen said. "I did what I had to do and actually acted on impulse."
He said that when wife Stine came home, telling him of the struggling dog she'd seen, he had felt compelled to go out and try and save it.
