At a glance the quick version
FCI and UKC standards set no weight. Wikipedia gives about 54-77 kg for males and 45-61 kg for females; Hill's gives 50-77 kg (110-170 lb) overall and Chewy 41-77 kg (90-170 lb).
Coat and looks how to spot one
medium-long, weatherproof double coat
A thick undercoat sits under a long, close-lying outer coat that ranges from fairly soft to coarse and may be straight or slightly wavy. Males in particular carry a lion-like mane over the neck and chest, and the front legs are feathered while the hind legs have full breeches. The body is big, muscular and still elegant, slightly longer than tall, with a deep chest and a calm, confident bearing. A black mask on the face is a defining feature.26
Personality what they are like
A friendly, even-tempered giant that bonds closely with the whole family and is known for being especially kind with children. Leonbergers are neither timid nor aggressive; they tend to size up a situation quietly and may simply place themselves between their people and a stranger rather than make a fuss. They learn readily, like to be included in family life and are often described as tuned in to their owners' moods.2459
Daily activity how busy a day looks
Needs daily activity plus mental work. Hill's suggests at least an hour a day of mixed exercise and brain games; The Royal Kennel Club lists more than two hours a day. Brisk walks, hiking, supervised swimming, obedience, agility and draft work all suit the breed.4758
Grooming and care the hands-on bits
Brush thoroughly at least once a week, and daily during the heavy spring and autumn moult, as the double coat sheds all year. Bathe occasionally (every 4-6 weeks is a common routine), check ears weekly, trim nails every 3-4 weeks and brush teeth regularly.475
Home where they are happiest
Best in a large home with a large, securely fenced garden; a rural setting suits the breed well. Not an apartment dog. The weather-resistant coat means it is happy outdoors in wet and cold conditions, but it should live with the family rather than apart from it.75
Food basics what goes in the bowl
A complete food formulated for large or giant breeds, with a large-breed puppy formula during growth so the frame develops at a steady pace. Keep the dog lean by measuring portions and adjusting to activity.45
Company who they like around
A strongly family-oriented dog that wants to be part of daily life. Usually gets on well with other dogs and can live happily with cats, especially when raised together. Early socialisation and short, positive, consistent training sessions work best; supervision with small children is sensible simply because of the dog's size.54
The story where it all began
The breed is credited to Heinrich Essig, a town councillor, mayor and animal dealer of Leonberg near Stuttgart. Starting in the 1830s he crossed a black-and-white Landseer-type Newfoundland female with a male 'Barry' dog from the Great St Bernard Hospice, then added further St Bernard lines and the Pyrenean Mountain Dog over several generations. His goal was a dog that looked like the lion on Leonberg's town crest, and the first dogs registered as Leonbergers were born in 1846. Essig was a gifted promoter, and his dogs went to royal households across Europe, including Empress Elisabeth of Austria and Napoleon III; Leonbergers also appeared in AKC stud books between 1887 and 1902. After Essig died in 1889, breed clubs formed from 1891 and artist Albert Kull wrote the first breed standard. In everyday life the breed became a valued farm, draught and watch dog in Baden-Württemberg. Both world wars brought it close to vanishing. After the First World War, Karl Stadelmann and Otto Josenhans found only about 25 dogs, five of them suitable for breeding, and in 1922 a group of breeders rebuilt the population. Numbers fell again in the Second World War, and today's Leonbergers trace back to the eight dogs that came through it. The German club reformed in 1948, an international union of Leonberger clubs was founded in 1975, the Leonberger Club of America followed in 1987, and the AKC granted full recognition in 2010.21036
