Legend has it that Squire Aubry de Montdidier's dog witnessed the assassination of his master, an intimate friend of the King of France and harassed the murderer, who was jealous of Aubry, so much that the King ordered a duel between Macaire and Aubry's dog. The assaults where so violent that Macaire, the assassin confessed his crime and was executed. So "chien d'Aubry" became "chien de Brie" or Briard.
The picture is of Rokedi, a two and a half year old Briard who belongs to a friend who is 87 years old. He is a perfect gentleman who drinks tea in the afternoon and champagne before dinner.
