Breed facts

  • 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).
  • 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 a pleasant temperament.
  • The first dogs registered as Leonbergers were born in 1846 and had many of the prized qualities of the breeds from which they were derived.
  • The legend is that the dogs were bred to be an homage of the lion in the town crest and coat-of-arms animal of Leonberg, the lion.
  • The Leonberger dog became popular with several European royal households, including Napoleon II, Empress Elisabeth of Austria, the Prince of Wales, Otto Von Bismarck, Emperor Napoleon III, and Umberto I of Italy.

Size and appearance

The Leonberger is a large, muscular, and elegant dog with balanced body type, medium temperament, and dramatic presence. The head is adorned with a striking black mask. Remaining true to their early roots as a capable family and working dog and search-and-rescue dog (particularly water), the surprisingly agile Leonberger is sound and coordinated, with both strength in bearing and elegance in movement. A sexually dimorphic breed, the Leonberger possesses either a strongly masculine or elegantly feminine form, making gender immediately discernible. The breed has webbed paws and a thick, dense double coat.

Personality and behavior

First and foremost a family dog, the Leonberger's temperament is one of its most important and distinguishing characteristics. Well socialized and trained, the Leonberger is self-assured, insensitive to noise, submissive to family members, friendly toward children, well composed with passersby, and self-disciplined when obliging its family or property with protection. Robust, loyal, intelligent, playful, and kindly, they can thus be taken anywhere without difficulty and adjust easily to a variety of circumstances, including the introduction of other dogs. Proper control and early socialization and training are essential, as this is a giant breed. "This is an outstanding water rescue dog. Only a short period of training it needed to augment its natural instincts." Its double-layered waterproof coat traps air and aids in buoyancy. Webs between the toes make for a powerful swimmer.
