Origins & history
A story told
Like the Saint Hubert Dog, it was a running dog that made up the French royal packs between the years 1250 to 1470. According to Charles IX (1550–1574), they were introduced to France by Louis IX (1226–1270) who allegedly encountered these dogs for deer hunting originating from Tartaria during his captivity during the Seventh Crusade and subsequently brought a pack back to France. In the 16th century, it is called the grey dog. According to Jacques du Fouilloux (16th century), the grey dog is a versatile hunting dog the color of a hare. They have hard hair, and are the ancestors of French griffon breeds. However, hard hair is mentioned neither by Charles IX nor by du Fouilloux, and it is possible that hard hair was acquired through later crosses with hard-coated French dogs. They were stubborn and determined dogs during hunts. By the 19th century, specimens became practically impossible to find.
