What matters most
Especially with a Leonberger, choosing the right breeder is the single most important decision you'll make. Serious breeders consistently test the parents for inherited conditions, prioritize healthy early socialization, and stay accountable long after handover. A cheap puppy without health screening tends to become the most expensive dog later on.

The real vibes check
A Leonberger is like a living rock in the surf—he brings a sense of calm that immediately fills the room. When 70 kilos of dog lean trustingly against your leg, nothing can throw you off balance. You aren't getting a high-energy athlete, but a majestic guardian who keeps his family together with stoic serenity.
The Leonberger is an impressive presence. It belongs to FCI Group 2, Section 2.2, the Molosser mountain type. He has a powerful stature and is characterized by his long, thick fur. Its name comes from its lion-like appearance, with its mane and bushy tail particularly prominent. The ears are medium sized and droopy, while the eyes are gentle and expressive. The Leonberger's body is muscular, with a deep chest and strong legs. There is no distinction between performance and show lines in this breed. The Leonberger was bred to combine a balanced, powerful appearance with a friendly and gentle nature.
The Leonberger is a dog that stands out for its calm and balanced temperament. He is extremely people-oriented and tends to form strong bonds with his family. His gentle nature makes him a wonderful family dog that also gets along well with children. Thanks to its history as a working dog, the Leonberger has a natural instinct to protect and help. It can be used as a rescue dog, therapy dog or even as a guard dog. Despite its size and strength, it displays extremely controlled behavior and is rarely aggressive. Leonbergers are not known for being hyperactive. While they appreciate exercise and mental stimulation, they are just as happy when they can simply relax around their humans. However, you should make sure that your Leonberger is not under-challenged, as this can lead to behavioral problems. Leonbergers don’t like loneliness at all. It is important that he learns to stay alone sometimes, but this should not become the rule. As part of the family, he wants to be involved in daily activities. The Leonberger is not prone to hunting behavior, but due to its size and strength it can make its own decisions if not guided properly. It is therefore important that he learns from the start to listen to commands and to heel, especially when other animals are nearby. His alertness and protective instinct make him a natural guardian of the house. He will not hesitate to protect his family if necessary. At the same time, he is not a barker and only barks when there is a reason. The Leonberger is a breed that is particularly suitable for people who are looking for a loyal companion. He offers protection without being aggressive and is gentle and loving with his family. However, it is important to remember that his size and grooming needs should not be underestimated. The Leonberger needs regular care and enough space. In addition, he should not be kept as a purely outside dog, but rather viewed as part of the family. His calm nature and his affection for people make him an excellent family dog who can enjoy a balanced life in a rural environment as well as city life, as long as he gets enough exercise and mental stimulation.

Fun Fact!
Did you know that the Leonberger was originally bred in the city of Leonberg, Germany in the 19th century to bring to life the city's coat of arms, which features a lion?
Leonbergers are considered calm and sociable dogs. They are also territorial and alert and can be unfriendly towards strangers. As with many large breeds, problems with the musculoskeletal system are also common in this type of dog. They also have a rather short life expectancy.
Leonbergers can be kept both in the city and in the country, but they need enough space. A house with a garden is ideal. It is important to remember that Leonbergers are very people-oriented and like to be part of family life. Small children are usually not a problem, but as with any breed of dog, handling should be supervised. In relation to other pets, including cats, Leonbergers are generally tolerable, especially if they are used to it from an early age.
Lives for its family — the born family companion.
Extraordinarily patient and loving — a true family dog.
Actively enjoys the company of other dogs.
Can manage in the city, but only with very active owners.
Owning a dog is a privilege, but it's also a real responsibility. Before you bring one into your life, be honest with yourself about the commitment it takes.
The upbringing of a Leonberger should be consistent but loving. They are intelligent and willing to learn, but can also be a little stubborn. It is important to start training early and use positive reinforcement. Leonbergers are physically strong, so it is important to teach them to walk on a leash. They don't tend to be "ball junkies" but it is still advisable to ensure a balance between playing and training. Leonbergers are versatile dogs and are suitable for various activities such as dog training or lifeguarding. It's also good to give them mental challenges to keep their brains occupied. Frustration tolerance and impulse control are important skills that should be encouraged in training to ensure that the Leonberger is balanced and happy.
A balanced diet is crucial for your Leonberger’s health. It is advisable to choose a high-quality food that is specifically tailored to the needs of large dog breeds. Due to their size, Leonbergers can be sensitive to rapid growth during puppyhood, so it is important to choose a food with appropriate nutrient levels. When it comes to grooming, Leonbergers have a thick undercoat and a long top coat that requires regular grooming. You should brush the coat thoroughly at least once a week to avoid mats and remove dead hair. During the moulting phases, they shed heavily, requiring more frequent brushing. Leonbergers cope well with the climate in Germany; their thick fur protects them from the cold.
| Care Level Regular brushing and occasional professional grooming. | Moderate |
| Exercise Needs Needs several hours of serious exercise every day. | Very active |
| Shedding Hair everywhere, always — no white clothing survives. | Very heavy |
| Trainability Willing to learn with clear rules and regular training. | Balanced |

Health grade
In the Leonberger, size and genetic predispositions carry significant risks for hip dysplasia (HD), elbow dysplasia (ED), and severe neurological disorders such as polyneuropathy 1, polyneuropathy 2, and leukoencephalomyelopathy. A responsible breeder counters this proactively and uses the mandatory genetic tests and X-ray examinations of the Deutscher Club für Leonberger Hunde e.V. prior to mating. Have the official test results of the parent animals shown to you: for HD, only A–B is permitted, and for ED, only 0–1; for polyneuropathy 2, both parents must be clear, and for polyneuropathy 1 as well as leukoencephalomyelopathy, a carrier may only be mated with a clear partner.

Illustrative imageThe Leonberger breed was developed in the city of Leonberg in Baden-Württemberg, Germany. In the mid-19th century, the first mayor of Leonberg, Heinrich Essig, began breeding dogs intended to reflect the city's coat of arms, which features a lion. It is believed that Essig crossed Landseers with St. Bernards, later adding Great Pyrenees to the mix. The result was the Leonberger. This new breed quickly gained popularity, particularly as a draft dog and a companion for the nobility. The Leonberger was recognized as an independent breed by the Fédération Cynologique Internationale (FCI) in 1949.
The Leonberger was bred as an imposing companion and guard dog, designed to embody the appearance of a lion.

Owners almost unanimously describe the Leonberger as a calm, deeply relaxed family companion. Many point to its unusually high threshold for stimulation; with children in particular, the breed is usually good-natured, patient, and steady. Indoors the giant tends to keep a low profile, likes to lie right in the middle of things, and values close contact with the family, while it does not cope at all with kennel life or being kept outside on its own. Owners also appreciate that it rarely barks or yaps indoors without a reason.
At the same time, experienced owners stress that the sheer size of this dog shapes everyday life. Grooming the dense coat is often described as manageable but time-consuming, and you have to be able to live with huge amounts of hair at home and a dog with a real love of mud puddles and dirt. The Leonberger also takes logistical planning: from a large enough car trunk to XXL gear to much higher vet and food bills, the breed is a real factor in daily life.

On training and handling, forum reports clear up the misconception that the Leonberger is simply an easygoing dog that trains itself. It may be naturally unhurried, but it has a strong independent streak and likes to question whether a command makes sense. Blind obedience or a strong "will to please" is usually missing; this sensitive dog answers pressure or harshness with stubborn shutdown. Owners therefore agree on early, loving, but fully consistent leadership.
Adolescence in particular, and poor leash training, put owners to a hard test. When 50 to 70 kilograms lunge on the leash, holding on physically is barely possible. Several owners point out that young males especially can tend toward dominance and scuffling during this phase if they are not given clear limits. Contrary to some breed books, a few owners also report a real prey drive that needs to be channeled early on.
Health is the biggest emotional sore spot among owners and in breed groups. Many owners rave about the breed's wonderful character but struggle with its comparatively short life expectancy, which owner accounts often put at just 7 to 9 years. Forums keep returning to the argument that the trend toward ever bulkier, heavier dogs has not been good for the breed's health.
The recurring health problems owners name are mainly cancer, bone and joint conditions (such as HD and ED), heart disease, and the risk of bloat (gastric torsion). The breed-specific nerve disease polyneuropathy (LPN) also comes up regularly. Experienced owners therefore strongly advise newcomers to choose puppies only from breeders with strict health screening, and to be careful to keep exercise gentle in the first year so the fast-growing joints and skeleton are not overloaded.
