Its dense golden to red coat, mane and black mask give it a noble, lion-like look.\n\nIt is first of all a family dog: friendly, steady and fond of children. Its size, coat and long-term health need serious consideration from any future owner.","history":"In the 1830s the mayor of Leonberg, Heinrich Essig, claimed to have created the breed by crossing Newfoundland, St Bernard type and Pyrenean Mountain Dog. The first registered dogs were born in 1846 and became fashionable with European royalty. Some doubt Essig's story, as similar dogs may have existed earlier.\n\nThe two world wars nearly wiped the breed out, and today's dogs descend from a handful of survivors. Leonbergers have worked as farm dogs, draft dogs and water rescue dogs.","appearance":"This is a big, strong dog with a balanced build. Males stand about 71 to 80 cm and females 65 to 75 cm, with weights from roughly 45 to 77 kg. It has a black mask, pendant ears, webbed feet and a long, water-resistant double coat with a mane on adult males.","personality":"Leonbergers are self-assured, calm and friendly. They are devoted to family, patient with children and usually easy with other dogs and visitors when well socialised.\n\nBecause of their size, early training and socialisation matter. They are intelligent and playful but dislike being left out of family life.","care":"They need daily walks and enjoy swimming, but not extreme exercise while young and growing. The coat needs thorough brushing a few times a week and heavier care during the shed.\n\nThey suit homes with space and a garden, and do poorly in hot climates.","health":"The breed has a small gene pool and a fairly short lifespan, often 8 to 10 years. Cancer, joint problems such as hip dysplasia, polyneuropathy, hypothyroidism, bloat and heart disease are among the concerns. Choose breeders who health-test."},"recognition":{"fci_number":145,"fci_standard_url":"https://www.fci.be/en/nomenclature/145.html","akc_url":"https://www.akc.org/dog-breeds/leonberger/"},"sources":{"wikipedia":"https://en.wikipedia.org/wiki/Leonberger","wikidata":"https://www.wikidata.org/wiki/Q38487","wikipedia_revision":1368883093},"profile":{"written_by":"AI model (Claude Sonnet) from the sources above","written_at":"2026-10-15T13:37:29Z"}}}
