Leonberger
A majestic giant German breed with a lion-like mane and gentle disposition. Calm, friendly and devoted, an excellent family dog, but huge, heavy-shedding and short-lived.
Leonberger scorecard
Overview
The Leonberger is a majestic giant breed from Germany, distinguished by its lion-like mane, large frame and notably gentle disposition. Standing around 65–80 cm at the shoulder and weighing roughly 45–77 kg, it is one of the larger breeds kept as a family companion, yet it is renowned for being calm, friendly and devoted. It is recognised by the FCI and The Kennel Club, which places it in the Working group.
Despite its imposing appearance, the Leonberger is a kindly, even-tempered dog that is typically wonderful with children and well-balanced in temperament. Its working heritage includes water rescue and draught work, and it retains a love of swimming and a willingness to work. As with all giant breeds, however, the Leonberger comes with a shorter lifespan, very heavy shedding, drool and substantial care costs, so ownership is a considerable and lifelong commitment.
Good to know — a Leonberger needs plenty of space and manageable for committed beginners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The Leonberger was developed in the town of Leonberg in south-western Germany in the mid-19th century, traditionally attributed to Heinrich Essig, who is said to have crossed large breeds — including the Newfoundland, the Saint Bernard and the Pyrenean Mountain Dog — with the aim of producing an impressive, lion-like dog. The breed's name and the lion on the town's coat of arms are part of its enduring story.
Leonbergers became popular as estate and farm dogs, valued for draught work, guarding and water rescue. The breed suffered drastic declines during both World Wars, and the modern population was rebuilt from a small number of surviving dogs by dedicated enthusiasts. Today the Leonberger is kept primarily as a family companion and is recognised internationally, with breed clubs maintaining its working heritage through activities such as water work.
Temperament & family fit
Leonbergers are celebrated for their calm, friendly and devoted nature. They are typically gentle and patient, often excellent with children, and well-disposed towards other dogs and pets when properly socialised. Self-assured and steady rather than nervous or aggressive, a well-bred Leonberger is a confident, good-natured giant that takes family life and visitors in its stride.
They are affectionate, people-oriented dogs that form strong bonds and like to be involved in family activities; they do not thrive when isolated. Their working background gives them a love of swimming and a willingness to learn, and many enjoy water work and gentle tasks. Their sheer size means early training and socialisation are essential to ensure that this powerful, friendly dog is also a well-mannered one.
- Families with children of all ages
- Owners ready for consistent training
- Active homes with plenty of space
Training & intelligence
Although large and strong, the Leonberger is intelligent, biddable and keen to please, which makes early, positive training effective. Because an adult is so big and heavy, good manners — calm greetings, walking nicely on a lead and solid basic obedience — must be instilled while the dog is still a manageable puppy, using reward-based methods that suit its sensitive, co-operative temperament.
Thorough early socialisation produces a confident, steady adult comfortable with people, children, animals and everyday situations. Many Leonbergers enjoy water rescue work, carting and other gentle activities that reflect their heritage and provide mental and physical engagement. Owners should remember that giant breeds mature slowly, so patience and consistency through the first couple of years are important.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Keep sessions short, calm and consistent
Exercise needs
A healthy adult Leonberger typically needs around an hour a day (roughly 60–80 minutes), split across walks, play and a little training. A good sniffy walk, some play and a little training usually keeps them content. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
The Leonberger carries a thick, water-resistant double coat with a pronounced mane, and it sheds very heavily — particularly during seasonal moults, when grooming becomes a daily task. Regular brushing several times a week (and more during moults) is needed to prevent matting, especially behind the ears and on the feathering. Owners should also expect a degree of drooling and the mess that a large, water-loving coat brings. Routine ear, nail and dental care round out the regime.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding considerations
Feed a complete, good-quality diet formulated for large or giant breeds, using appropriate growth food for puppies to encourage slow, steady development that protects the joints. Portions should be matched to age, size and activity, with weight kept in check to avoid placing extra strain on the skeleton. As a deep-chested giant, the Leonberger benefits from divided meals and from avoiding vigorous activity immediately around feeding, given the risk of bloat.
Leonberger health & costs
Before bringing a Leonberger home it pays to budget for the whole picture — food, insurance, grooming and routine vet care all add up. The figures below are typical UK estimates for a healthy adult; your real costs vary with where you live, your dog's health and the cover you choose.
Food
£850–1,200 / year
Complete food sized to weight & life stage
Insurance
£45–85 / month
Lifetime cover — varies by age, breed & area
Grooming
£400–700 / year
Regular professional grooming
Routine vet care
£200–450 / year
Vaccines, flea/worm, annual check
As a giant breed, the Leonberger has a relatively short lifespan of around 8–10 years and is prone to several serious conditions, so buying from a breeder who health-tests is especially important. Orthopaedic problems, heart disease and certain inherited neurological and cancerous conditions are recognised concerns in the breed.
The Leonberger is, sadly, predisposed to some cancers, including osteosarcoma, and to inherited neuromuscular conditions for which DNA tests exist. Prospective owners should ask breeders for evidence of hip, elbow, heart and relevant DNA screening, and should learn the signs of bloat. Following Kennel Club and breed-club health guidance is essential, as the breed carries a number of well-documented hereditary risks.
Common health conditions to be aware of
- Hip dysplasia — abnormal hip development leading to arthritis; breeding dogs should be hip-scored.
- Elbow dysplasia — developmental joint disease causing lameness in large breeds; screening is advised.
- Leonberger polyneuropathy (LPN/LPPN3) — inherited neuromuscular disorders affecting nerves and muscles; DNA tests are available and breeding stock should be screened.
- Osteosarcoma and other cancers — the breed is predisposed to certain cancers, a notable cause of death.
- Gastric dilatation-volvulus (bloat) — a sudden, life-threatening twisting of the stomach in deep-chested dogs; owners must know the signs.
- Inherited heart disease — cardiac conditions occur in the breed; cardiac screening of breeding dogs is recommended.
These reflect typical, size- and coat-related risks for dogs like the Leonberger; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.

Bringing home a Leonberger puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.
New puppy checklist →Caring for a senior Leonberger
As they age, watch weight, joints and teeth, switch to a senior diet if your vet advises, keep exercise gentle but regular, and consider orthopaedic bedding and ramps. Twice-yearly vet checks help catch issues early — larger breeds age sooner, so start senior care from around 6–7 years.

It is one of the biggest breeds kept as a family companion, so prospective owners need the space, strength and budget that come with managing such a substantial dog.
What is a Leonberger's temperament like?
Despite its imposing, lion-like appearance, the Leonberger is renowned for being calm, friendly and devoted. It is typically gentle and patient, often excellent with children and well-disposed towards other dogs and pets when properly socialised. Self-assured and steady rather than nervous, it is a confident, good-natured giant that bonds closely with its family and likes to be involved in daily life.
How long do Leonbergers live?
As with most giant breeds, the Leonberger has a relatively short lifespan, typically around 8–10 years. Larger dogs generally age faster than smaller ones, so this is a breed where owners should be prepared, emotionally and practically, for fewer years together. Choosing a health-testing breeder and keeping the dog at a healthy weight support the best chance of a full, comfortable life.
Do Leonbergers shed a lot?
Yes, considerably. The Leonberger carries a thick, water-resistant double coat with a pronounced mane and sheds very heavily, especially during seasonal moults when grooming can become a daily task. Brushing several times a week is needed to prevent matting, particularly behind the ears and on the feathering. Owners should also expect a degree of drooling that comes with such a large, water-loving dog.
How much exercise does a Leonberger need?
The Leonberger has fairly moderate exercise needs for its size, with around an hour or more of activity a day suiting most adults. It enjoys daily walks and especially swimming, which it loves and which is kind to its joints. Care must be taken not to over-exercise growing puppies, whose developing joints are vulnerable to damage from too much strenuous activity.
What health problems are Leonbergers prone to?
As a giant breed, the Leonberger can be predisposed to orthopaedic problems, heart disease, certain inherited neuromuscular conditions and some cancers, including osteosarcoma. Being deep-chested, it is also at risk of bloat. Ask breeders for evidence of hip, elbow, heart and relevant DNA screening, learn the signs of bloat, and follow Kennel Club and breed-club health guidance. Always speak to your vet about any concerns.
Are Leonbergers good with children?
Leonbergers are generally gentle and superb with children, being patient and even-tempered by nature. Their sheer size means interactions with small children should always be supervised, simply to avoid accidental knocks. Early training and socialisation are essential so that this powerful, friendly dog is also well-mannered. In the right home with space and time, it makes a calm, affectionate family companion.
Is a Leonberger a good first dog?
The Leonberger suits owners who can manage a giant, devoted dog, ideally with a secure garden and access to safe water for swimming. Its heavy shedding, drool, slow maturity and substantial feeding and veterinary costs make it a considerable, lifelong commitment that may not suit a first-time owner. For those prepared for its needs, however, it is a magnificent and rewarding family dog.
Are Leonbergers good with children?
Excellent with children of all ages. As a general guide, Leonbergers tend to be patient and tolerant. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does a Leonberger need?
As a healthy adult, a typical Leonberger needs around an hour of exercise a day (60–80 minutes), split across walks plus play. A good sniffy walk plus some play and training usually keeps them happy. Puppies, seniors and dogs with health conditions need less — ask your vet.
Do Leonbergers shed a lot?
Heavy shedding. Coat upkeep is high upkeep — plan on frequent brushing and regular trips to a groomer.
Are Leonbergers easy to train and good for first-time owners?
Manageable for committed beginners. Leonbergers are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Leonbergers bark a lot?
Quiet. They are usually fairly easy-going about barking, though any dog will bark if bored or under-exercised.
Are Leonbergers good with other dogs?
Sociable with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Leonbergers suit flats or smaller homes?
Needs plenty of space. A Leonberger really needs plenty of space and a lot of daily activity — not ideal for a small flat.
