Gris de Saint-Louis (Grey Saint Louis Hound) is an extinct breed of dog which originated in Medieval times.

[4] However the rough coats were not mentioned by Charles IX or du Fouilloux, and it has been suggested they were acquired later through interbreeding with indigenous French hounds.

[1] They were headstrong, wide-casting hounds, inclined to change or overshoot, but determined in their pursuit of a quarry to the death.

However, by the nineteenth century, like the St Hubert, they had become virtually impossible to find, because of mixed breeding and the effect of the Revolution on French hunting.

[7] However, Turberville did not make it clear that his book was a translation, and it is highly possible that people mistakenly believed his work was about English hunting.
