Bullenbeisser (also known as the German Bulldog) was a breed of dog known for its strength and agility. The breed was closely related to the Bärenbeisser (some believe that the two breeds were the same; the names mean “bull-biter” and “bear-biter,” respectively), and the Boxer. It was in all its aspects similar to the present Alano Español and very alike to the Dogo Argentino, not only in aspect, but also in usage. The Bullenbeisser became extinct by crossbreeding rather than by a decadence
Chien-Gris also known as le Gris de St. Louis, this now extinct dog originated in Medieal times and was a scent hound for the royal families of France.

It is important to note this is not the same breed as the Greyhound. http://en.wikipedia.org/wiki/Chien-gris
