The Tale of Greyfriars Bobby — Lavinia Derwent

Bobby, a lively little Skye Terrier, adores his master Auld Jock and when the old man dies, Bobby refuses to leave his grave in Greyfriars Churchyard in Edinburgh. By day, he plays with local orphans and eats at a nearby tavern, but every night for fourteen years Bobby returns faithfully to sleep by his master's grave.

Based on a true story.
