Do you have a favourite fictional dog? Maybe from a movie or book you read when you were young or maybe you just have a favourite mythological dog story.
I've never read Homer's Odyssey but I heard the story of Argus recently on a podcast. Might have been The Rest is History? Anyway here's an extract from Wiki...
In Homer's Odyssey, Argos sometimes referred to as Argus, is the legendary faithful dog of Odysseus. Bred to be a hunting dog before Odysseus leaves for the Trojan War, Argos is neglected after Odysseus is presumed dead. Twenty years later, Odysseus returns to Ithaca and finds him lying in piles of manure, immobile from old age and neglect, and infested with parasites. When Argos sees Odysseus, he immediately drops his ears, wags his tail and recognizes him. Disguised as a beggar, Odysseus cannot greet his dog without revealing his identity, but secretly weeps. Upon seeing his master return home, Argos dies.
Heartbreaking.
