Hachiko has been named the world's most loyal dog, and for good reason. Those of you who don't know about the amazing Japanese Akita who lived over 80 years ago, you should. When Hachiko's owner died unexpectedly, without the dog's knowledge, Hachiko started a ten year long wait for his owner to return. Many consider this story one of the saddest, some consider it remarkable. Check out this rare photo that was discovered of Hachiko waiting for his owner!
