Leonberger History

The Leonberger was established in 1846 in Leonberg, Germany. A breeder named Heinrich Essing crossed three breeds to come up with a dog that looked like a lion, as well as retaining the strengths of the individual breeds. He used the Saint Bernard, the Newfoundland and the Great Pyrenees. This combination gave the dog a large and muscular body, with a medium long and silky coat. It was imported to Russia in the 1800s and has been owned by several royal families, including:

• Empress Elizabeth of Austria
• King Umberto of Italy
• Napoleon II
• The Prince of Wales

By the late 19th century, the breed had found home with many farmers who used them to keep livestock. During World Wars I and II, the breed’s extinction was almost total in Germany. According to historians, only five survived World War I, and the eight that survived World War II can be credited as the ancestors of all present-day Leonbergers.

The first Leonberger dogs were imported into the United States in the 1970s and are becoming popular for their versatility and unusual appearance. The breed found itself back in the spotlight in 1997, when three Leonbergers appeared in the title role of “Buck” in the film “TheCall of the Wild: Dog of the Yukon.”
