The Grand Bleu de Gascogne is a breed of dog in the scenthound family, developed out of the Gascony province on the southwestern coast of France.
The Great Gascony Blue stands up to 70cm (27½ in) and weighs 35 to 39 kg (70½ to 77lb). The breed has an aristocratic-type head and low-set ears to help push the scent into the dog's nostrils. Its long, narrow legs and fully exposed claws help the dog to run swiftly. It has a smooth coat with black-mottled markings on a white base, which gives the breed a bluish tinge. Some dogs have tan markings on the head and muzzle.
Little is known about the temperament of this breed, since it is so rare.

Some now consider this breed dangerously rare, because of the aftereffects of World War II
