Leonberger University of Bern, Bern, Switzerland In the 1830s, Heinrich Essig, a dog breeder and seller and mayor of the town of Leonberg near Stuttgart in Baden-Württemberg, Germany, claimed to have created the Leonberger by crossing a female Landseer Newfoundland with a "barry" male from the Great St. Bernard Hospice and Monastery (which would later create the Saint Bernard breed). Later, according to Essig, a Pyrenean Mountain Dog was added, resulting in very large dogs with the long, white coats that were the fashion for the time, and pleasant temperament. The first dogs registered as Leonbergers were born in 1846 and

It is a taller, more narrow white dog with black markings not bred with a Newfoundland. The Newfoundland's extremely large bones give it mass, while its large musculature gives it the power it needs to take on rough ocean waves and powerful tides. These dogs have huge lung capacity
