Description

The Leonberger is a majestic and gentle giant, bred in Germany to resemble a lion and serve as an all-purpose working dog and noble companion. Known for their calm temperament and great affection toward family, Leonbergers are especially patient and gentle with children, often called “gentle giants.”

Their thick, luxurious double coat requires regular brushing (at least a few times a week) to prevent mats and manage heavy seasonal shedding. While intelligent and eager to please, Leonbergers can be slow to mature and may need extra patience during training. They benefit from daily moderate exercise, socialization, and time spent close to their people.

History

Origin: The Leonberger traces its origins to the town of Leonberg in Baden-Württemberg, Germany, during the mid-19th century. Heinrich Essig, a politician and dog breeder, claimed to have created the breed by crossing a Landseer Newfoundland with a Saint Bernard, later adding a Pyrenean Mountain Dog. Essig aimed to develop a large, majestic dog resembling the lion on Leonberg's town crest. While the exact genetic history is debated, similar dogs existed in the region as early as the 17th century.
Development: The Leonberger was intentionally bred to combine strength, size, and a gentle temperament suitable for both working and companionship. Initially popular among European royalty, including Napoleon III and Empress Elisabeth of Austria, it gained recognition for its versatility in tasks such as cart-pulling and water rescue. The breed nearly went extinct during World War I but was revived by dedicated breeders who rebuilt its population from just five suitable dogs. By 1922, organized breeding efforts resulted in 350 registered Leonbergers.
Recognition: The Leonberger was officially recognized by the Fédération Cynologique Internationale (FCI) in 1948 and entered the American Kennel Club (AKC) Working Group in 2010. Today, it is recognized by major kennel clubs worldwide for its distinctive tawny coat and black mask. The breed standard emphasizes its regal appearance, muscular build, and calm demeanor.
Today: Leonbergers are cherished for their gentle nature, intelligence, and adaptability as family companions and working dogs. They excel in activities such as therapy work, water rescue, and cart-pulling while being affectionate with children and families. Despite their size, they are known for their calm disposition and thrive in homes that can provide ample space and exercise. The breed remains popular globally for its majestic appearance and loyal personality.
