Origins
Where does it come from?
The Leonberger owes its name to the German town of Leonberg, near Stuttgart. Between the years 1830 and 1840, Heinrich Essig undertook to create a very large dog with a lion-like appearance by crossing in particular Newfoundland, Saint Bernard and then Pyrenean Mountain Dog. Used as a guard and draft dog on farms, its population declined sharply after the two world wars before being preserved and then definitively recognized by the FCI in 1955.
