One of the larger French hunting hounds with aristocratic long head. The Grand Bleu de Gascogne is a Scenthound of ancient line-age, eminently French. They are descended from the scenting dogs of Gaul and the Phoenician hound trade, and are one of the two types from which most modern hound breeds developed.
The Grand is probably the closest, of the four Blue de Gascogne breeds, to the ancient hounds in size and build. Gascony Province, the specific area of their rootstock and development, is located on the southwestern coast of France.
