- The Leonberger takes it name after the town of Leonberg in Germany
- The Leonberger breed was originally created by Heinrich Essig (1808–87) in the German town of Leonberg, in what was then the kingdom of Württemberg
- The coat of arms of the town of Leonberg, Germany, was allegedly the inspiration for the first breeder of the Leonberger, Heinrich Essig (maybe you can say that the Leonberger looks the way it does because Germans were bad at drawing lions back then)
- The breed was first registered in 1846
- According to Essig, the Leonberger is a cross between a Saint Bernard, a Newfoundland, and what is thought to be Great Pyrenees or a Pyrenean Mastiff (not known which). In reality the mixing and matching went back and forth between these three breeds throughout history and it may be more complicated.
- In the 1870s, Leonbergers were brought to Newfoundland to invigorate the stock of Newfoundland dogs
- In 1879 President Ulysses S. Grant gave two Leonbergers gold medals
- The first Leonberger breed standard was created in 1895
- Leonbergers were used in the World War I to pull ammunition carts and cannons, which was one of the reasons the breed was decimated during World War I
- Leonbergers have webbed paws
- Leonbergers are double coated
- Until 1985, there were only seventeen Leonbergers known to be living in the United States
- The Leonberger Club of America was founded in 1985
- The Leonberger was recognized by the American Kennel Club in 2010 as its 167th breed.*
- The Leonberger is unique in the AKC for being the only dog in the Working Group originally bred to be a companion.†
- According to an estimate prepared by BioMed Central, there were around 30,000 Leonbergers in the world in 2020 (registered only).‡
- There are around 3,300 Leonbergers in North America—2,300 in the United States and 1,000 in Canada.§
- The five countries with the most Leonbergers, in order, are France, with nearly 8,000; Germany, with more than 4,000; and Great Britain, the United States, and Sweden, with approximately 2,300 each.¶
- The country with the highest number of Leonbergers per capita is Finland, with nearly 2,000 Leonbergers among a population of 5.5 million people.
