Tsunami dog found alive and well in Japan after THREE WEEKS adrift at sea on a floating house

It appears almost too good to be true, but this little dog has been found alive and well adrift at sea, an astonishing three weeks after the tsunami that devastated Japan.

Members of the Japan Coast Guard came across the dog on Friday as they were conducting an aerial search of the area.

Against all the odds, the dog appears to have survived by living in a partially submerged house that had been swept out to sea.

Local television showed showed pictures of the dog scampering around the roof of the house before it disappeared inside through a hole in the roof.

Rescuers had hoped to find more tsunami survivors living inside the house but after tearing the roof open, it was found to be empty apart from the dog.

Despite its three weeks at sea, the medium-sized brown dog seemed to be in reasonably good condition considering its ordeal.

The discovery of the dog is a rare glimmer of hope in Japan where thousands of people are believed to have perished in the disaster.

The nation is now gripped by the ongoing nuclear threat posed by the unstable Fukushima plant as workers continue to battle to restore vital cooling systems damaged by the quake.
