The Anglo-Français de Petite Vénerie is a medium-sized breed of dog used in hunting as a scenthound, usually in packs. It is one of the Anglo-French hound breeds which were created by crossing French scenthounds with English (Anglo) foxhounds. The name "Petite Vénerie" does not mean that dogs of the breed are "petite" or small, but rather that it is used to hunt small game.
The dogs of the breed are petite and small.
While it says the name ""Petite Vénerie" does not mean that dogs of the breed are "petite" or small, but rather that it is used to hunt small game", this does not necessarily imply the dogs aren't also petite or small. It's not out of the realm of possibility.
