Rare photos have emerged of Hachiko, the loyal dog. Hachiko would greet his human companion Ueno every day at the train station after work; Ueno died suddenly on the job, but Hachicko still waited for 10 long years for his return.
See the movie HASHI; true story (with Richard Gere). In Scotland I saw a famous dog statue next to a pub where the owner and his dog are buried. The dog never left the grave site for years after the owner died so they put up a monument with the story.
