Billy is derived on the basis of three beautiful, unfortunately, now extinct French hounds XIX century .: SERIS, montebef, and Larry, from which Billy inherited high growth and color with orange spots, strength, speed, and a great flair. M.G. Jublo du Riveau prophetically foresaw the result of such a mixture of blood. This hound, like its ancestors, is intended for hunting in a pack, specializing in deer.
