Leonberger Breed Information


The sociable, steady Leonberger has a life expectancy of 8 to 9 years.

The Leonberger was developed in Leonberg, Germany, by a businessman named Heinrich Essig in the early half of the 19th century. Essig was a specialist in animal trading and had numerous rare animals. He created the Leonberger to physically represent Leonberg’s town crest – the lion. Essig claimed to have bred the Leonberger using the Landseer Newfoundland, Saint Bernard and Pyrenean Mountain Dog. However, today’s experts believe there are more, unknown dogs in the Leonberger’s ancestry.

The Leonberger weighs 100 to 130 pounds and measures 25.5 to 31.5 inches.

The Leonberger has a long coat and sheds moderately most of the year. Twice a year, in the spring and fall, the Leonberger sheds profusely. The Leonberger should be brushed daily and bathed when necessary. Like all dogs, the Leonberger also needs basic grooming.
