In this article, we’ll cover everything you need to know about the Leonberger, from its history to physical traits to personality and health.

History of the Leonberger Dog Breed

Unlike most large breeds, the Leonberger, or simply Leo, was developed solely for the purpose of being a companion dog. However, over the years, many breed members were tasked with various working roles. 

Origins of the Breed

The Leonberger is a relatively new breed that was developed by the German politician and entrepreneur Heinrich Essig in the 19th century. Essig wanted a dog that looked like a lion and was loyal like a dog.

He achieved this by crossing Saint Bernards and Newfoundlands. Essig used the Saint Bernard for its size and strength and the Newfoundland for its thick coat and loyalty.

The Breed’s Role 

Despite being developed as a companion dog, the Leonberger’s working capacity was quickly recognized and breed members were used to pull carts and help workers on farms, pastures, and waterfronts. 

Famous Leonberger Owners 

Highly valued for its regal appearance, the Leonberger captured the hearts of royalty and famous people. Prominent names that owned Leonbergers include Napoleon III, Tsar Alexander II, the Prince of Wales, Richard Wagner, Sergei Rachmaninoff, and Giuseppe Garibaldi.

Recognition by Kennel Clubs

The Leonberger was first recognized by the German Kennel Club. The American Kennel Club (AKC) accepted the breed in 2010.
