The Leonberger appeared in Leonberg, Germany in 1846. Originally, the Leonberger was an attempt by Herr Heinrich Essig to create a dog that looked like a lion, part of the crest of Leonberg. What he created was a large dog with a tawny yellow coat and black points on the muzzle and ears.

During World War I, the breed nearly became extinct. Of 25 Leonbergers, only five were of breeding quality. Two Leonberger devotees, Stadelmann and Josenhans, began a club committed to saving the Leonberger. The breeding program was taken over by the German government during the war and was reestablished after the war by the Deutsche Club fur Leonberger Hunde.

The breed has a modest but growing following in the United States; United Kennel Club recognized the Leonberger in 1991.
