SENDAI (Kyodo) The Japan Coast Guard managed to save a small brown dog Friday from a floating rooftop 1.8 km off Miyagi Prefecture, three weeks after a massive tsunami ravaged the northeast coast.

The canine castaway was spotted by helicopter at around 4 p.m. by a special rescue unit from the 3rd Regional Coast Guard Headquarters, operating out of Yokohama.

The team's initial rescue attempt failed after the dog, perhaps scared by the hovering helicopter, jumped from the roof over to nearby driftwood.

A rescue boat with three guardsmen was then dispatched and succeeded in catching the pooch an hour later by using rescue stretchers.

The dog, which was wearing a black collar that had no indication of who its owner might be, was fed biscuits and sausages aboard the coast guard vessel and is behaving itself, the coast guard said.
