Greyfriars Bobby.

The heart wrenching story of the bond between a man and a dog, inseparable even in and until death.

According to Wikipedia "The best-known version of the story is that Bobby belonged to John Gray, who worked for the Edinburgh City Police as a night watchman. When John Gray died he was buried in Greyfriars Kirkyard, the graveyard surrounding Greyfriars Kirk in the Old Town of Edinburgh. Bobby then became known locally, spending the rest of his life sitting on his master's grave.

In 1867 Lord Provost of Edinburgh, Sir William Chambers—who was also a director of the Scottish Society for the Prevention of Cruelty to Animals—paid for Bobby's licence, and gave the dog a collar now in the Museum of Edinburgh.

Bobby is said to have sat by the grave for 14 years.He died in 1872 and was buried just inside the gate of Greyfriars Kirkyard, not far from John Gray's grave"

True or not, the story is one of many legends demonstrating the bonds that develop between humans and other animals.
For a species that is so cruel and uncaring to its own, I marvel at the forgiving bond so many faithful creatures can form with us.
This will be my entry for this weeks challenge on the theme of Bond.
