Leonberger
Also called Leo
Named for a lion and built like a bear, the Leonberger fills any room, then settles quietly into it.
The Leonberger is a giant German breed with a lion-like mane, a black mask and a reputation for gentleness with children. It can be a wonderfully calm family companion, but it comes with the shedding, costs and short lifespan that follow a very big dog.

Life with a Leonberger
A mature male Leonberger can weigh as much as 75 kg (165 lb) and stand close to 80 cm (31.5 in) at the shoulder, with a coat that makes him look bigger still. Females are noticeably smaller and lighter, but neither sex fits neatly into a hatchback or a narrow hallway. Size is the first thing to plan for, because it shapes where the dog sleeps, how you travel, what the vet bills look like, and how many years you can expect together.
The breed's origin story is tied to civic pride. Heinrich Essig, a dog dealer and councillor in the town of Leonberg, is often credited with crossing a Landseer-type Newfoundland with a Saint Bernard in the 1830s and 1840s, later adding a Pyrenean mountain dog, to create a dog that resembled the lion on the town's coat of arms. Essig sold his dogs to wealthy buyers across Europe, and Empress Elisabeth of Austria is said to have owned several.
The two world wars nearly ended the breed. Accounts differ on the exact numbers, but only a few dogs are said to have remained after 1945, and the modern population descends from the careful work of a small group of German breeders. That narrow base is one reason health testing matters so much today.
At home, a well-bred Leo is calm, sociable and patient, often gentle with children and polite with other dogs. It wants to be with its family, and a Leonberger kept outside and alone tends to become unhappy and destructive. Many are enthusiastic swimmers, a legacy of the Newfoundland blood, and will head for any lake they can find.
What stands out
Puppy growth
Leonberger puppies grow at a remarkable rate, often reaching 30 to 40 kg by six months, yet they take two to three years to finish maturing. Males in particular fill out slowly, gaining chest, mane and muscle into their third year. Your dog will look nearly adult while its bones and joints are still developing.

Leonberger questions
How big does a Leonberger get?
Males typically stand 72 to 80 cm (28 to 31.5 in) and weigh roughly 54 to 77 kg (120 to 170 lb). Females are smaller, around 65 to 75 cm (25.5 to 29.5 in) and 41 to 59 kg (90 to 130 lb). Most reach full height by about 18 months but continue filling out, especially through the chest and mane, until two or three years of age.
Are Leonbergers good family dogs?
Many are excellent with families. They tend to be patient, gentle and tolerant of children's noise, and they like to be in the middle of household life. Their size is the main risk, since a happy wag or a friendly lean can flatten a toddler. Supervise, teach the dog calm manners, and make sure children know not to climb on it or ride it.
Do Leonbergers like water?
Most love it. The Newfoundland ancestry shows in webbed feet, a water-resistant coat and a strong swimming style, and some dogs train for water rescue work. Introduce water gradually, choose safe entry points, and dry the coat thoroughly afterward, especially around the ears and in the thick undercoat, to prevent damp skin becoming irritated.
What is the difference between a Leonberger and a Newfoundland?
Both are giant, water-loving breeds, but the Newfoundland is heavier boned, usually black, brown or black and white, and has a denser, oilier coat. The Leonberger is lighter on its feet, with a lion-colored coat and a black mask. Leonbergers are often a little more active, while Newfoundlands are known for being exceptionally placid.
Why do Leonbergers have short lifespans?
Giant breeds in general age faster than small ones, and the Leonberger also has higher rates of some cancers and inherited diseases. The narrow genetic base left after the world wars may play a part. Health-tested parents, a lean body, joint-friendly exercise and early veterinary attention to any change give your dog the best chance of a long life.
