Did You Know?
The Leonberger was nearly extinct after World War I and World War II, with only eight dogs remaining after WWII. Dedicated breeders worked tirelessly to rebuild the breed, and today's Leonbergers descend from these eight survivors. The breed was created by Heinrich Essig, a dog breeder and politician from Leonberg, Germany, who wanted to develop a dog that resembled the lion on the town's coat of arms. Despite their size, Leonbergers are known for their "soft mouths," a trait that makes them excellent at carrying objects without damaging them. They are sometimes called "nanny dogs" because of their gentle, protective nature with children.
History and Origin
The Leonberger has a fascinating history that dates back to the mid-19th century in Germany, where they were deliberately created to resemble lions.
German Origins
The breed's development began in the 1830s in Leonberg, Germany, by Heinrich Essig, a dog breeder and town councilor. Essig aimed to create a dog that would resemble the lion featured on Leonberg's coat of arms. He crossed a female Landseer (Newfoundland-type) with a male Barry (Saint Bernard) from the Great St. Bernard Hospice, then later added a Pyrenean Mountain Dog to the mix.
The resulting dogs were large, impressive animals with the desired lion-like appearance. They quickly gained popularity among European nobility, including Empress Elisabeth of Austria, Napoleon II, Prince of Wales, and Emperor Napoleon III. Leonbergers were used as farm dogs, draft animals, and water rescue dogs, showcasing their versatility and intelligence.
Survival and Modern Development
Both World Wars nearly decimated the Leonberger breed. During World War I, most Leonbergers were either killed or died of starvation. After the war, breeders managed to rebuild the population, but World War II again brought the breed to the brink of extinction, with only eight Leonbergers surviving. Dedicated German breeders worked with these remaining dogs to reestablish the breed. The first Leonbergers were imported to the United States in the early 1970s, and the breed was recognized by the AKC in 2010. Today, Leonbergers are cherished family companions, therapy dogs, and water rescue dogs, maintaining the gentle temperament and versatility for which they were originally bred.

Temperament & Personality
The Leonberger's temperament combines gentle devotion with calm confidence, creating a reliable yet affectionate family companion.
Gentle & Devoted
Leonbergers are famously gentle and devoted to their families. Their calm demeanor and loyalty make them excellent family companions and "nanny dogs" for children.
Confident & Calm
Bred to be self-assured working dogs, Leos are naturally confident and calm in various situations. They're steady companions who rarely show nervousness.
Water-Loving
With their water-resistant coats and webbed feet, Leonbergers are natural swimmers who enjoy water activities. Many excel in water rescue work.
Social & Friendly
Leos are typically social and friendly with proper socialization. They usually get along well with other animals and people when properly introduced.
Important Temperament Considerations
Leonbergers are generally calm and gentle but require proper socialization from an early age due to their size. Their substantial stature means that even accidental bumps can be problematic, so they need to be taught appropriate behavior around people, especially children. They mature slowly, both physically and mentally, and may not reach full maturity until 3 years of age. Leonbergers can be reserved with strangers but should never be shy or aggressive without cause. Early positive experiences with various people, places, and situations are crucial for developing a well-adjusted adult. Their intelligent nature means they thrive on positive reinforcement training methods and do not respond well to harsh correction. Proper socialization helps prevent over-protectiveness.
Temperament Traits
Exercise & Activity Needs
Despite their large size, Leonbergers have moderate exercise requirements but enjoy regular activity and mental stimulation.
Daily Exercise
45-60 Minutes
Regular walks, play sessions, or swimming activities. Leos benefit from consistent, moderate exercise that engages both body and mind.
Avoid over-exercising puppies to protect developing joints.
Mental Stimulation
Daily
Training sessions, puzzle toys, and scent work provide necessary mental challenges. Their intelligent nature needs regular engagement.
Prevents boredom while accommodating their calm nature.
Water Activities
Weekly
Swimming, water retrieval, or other water-based activities. Leos are natural swimmers with water-resistant coats and webbed feet.
Excellent low-impact exercise for joint health.
Weekly Exercise Schedule
- Daily: 45-60 minutes of walking divided into multiple sessions
- 4-5 times per week: Short training sessions or interactive games
- Weekly: Opportunities for swimming or water play
- Ongoing: Access to appropriate chew toys and mental stimulation
Exercise Considerations
Leonberger puppies should not be over-exercised during their growth period to protect developing joints. Avoid strenuous exercise like long runs or jumping until they reach physical maturity around 18-24 months. These giant breeds are prone to joint issues, so maintaining a healthy weight is crucial. Leos are better suited to cooler climates due to their thick double coat, so exercise during cooler parts of the day in warm weather and provide plenty of fresh water. They enjoy a variety of activities including walking, hiking, swimming, and cart-pulling. Always use a sturdy leash and properly fitted harness for walks, as their strength can be difficult to manage if they pull. Be mindful of their size when choosing walking routes to avoid obstacles.
Diet & Nutrition
Proper nutrition is essential for Leonbergers, who require a carefully balanced diet to support their giant size and prevent rapid growth.
Puppy Diet
0-18 Months
Large breed puppy food formulated for controlled growth, fed 3-4 times daily. Proper calcium-phosphorus balance is crucial for bone development.
Puppies need frequent, measured meals for proper skeletal growth.
Adult Diet
1.5-6 Years
High-quality adult giant breed dog food with balanced protein and controlled calories. Adults typically need 5-8 cups daily, divided into two meals.
Adjust portions based on activity level and metabolism.
Senior Diet
6+ Years
Senior formula with joint support, controlled calories, and adjusted nutrient levels. Monitor weight as metabolism slows and adjust portions accordingly.
Seniors may need smaller, more frequent meals.
Nutritional Requirements
- Protein: Moderate levels from high-quality sources (22-26%)
- Fat: Controlled levels to prevent excessive weight gain
- Joint Support: Glucosamine and chondroitin for joint health
- Calcium-Phosphorus Balance: Crucial for proper bone development
- Portion Control: Critical to prevent obesity and related health issues
Feeding Considerations
Leonbergers are deep-chested dogs prone to bloat (gastric dilatation-volvulus), a life-threatening condition. Feed multiple small meals rather than one large meal, and avoid vigorous exercise before and after eating. Elevated feeding stations may actually increase bloat risk. Monitor for food allergies, which can manifest as skin issues. Always provide fresh water and avoid rapid eating by using slow feeder bowls if necessary. Leos are prone to obesity, which can exacerbate joint problems, so careful portion control is essential. Consult your veterinarian for specific dietary recommendations based on your Leonberger's age, activity level, and health status. The cost of feeding a Leonberger can be substantial due to their size.
Health & Care

Training & Behavior
Training a Leonberger requires patience, consistency, and an understanding of their intelligent but sometimes independent nature.
Training Approach
- Positive Reinforcement: Use reward-based training with high-value treats, praise, and affection
- Early Start: Begin training and socialization from 8-10 weeks old
- Consistency: Establish clear rules and expectations from the beginning

Socialization Needs
Early and extensive socialization is crucial for Leonbergers:
- Puppy Classes: Enroll in puppy kindergarten for early socialization
- Various Environments: Expose to different people, places, and situations
- Controlled Introductions: Supervised meetings with various people and animals
- Positive Experiences: Ensure new experiences are positive and not overwhelming
Training Tips
Leonbergers respond best to positive reinforcement methods and patient, consistent training. Their intelligence means they learn quickly but may challenge commands that seem arbitrary. Socialization is particularly important to ensure they develop into well-adjusted adults comfortable with their size. Training should focus on establishing reliable obedience and solid manners, with special emphasis on not jumping up or leaning on people due to their massive size. Remember that Leos mature slowly and may not reach full mental maturity until 2-3 years of age. Be patient and consistent, and celebrate small victories. These gentle giants excel when training is built on mutual trust and respect. Early leash training is essential for managing their size and strength.
Common Behavioral Issues
- Leaning: May lean against people, which can be problematic due to size
- Mouthing: May gently mouth hands during play or excitement
- Stubbornness: May ignore commands if not properly motivated
- Separation Anxiety: Can develop when left alone for long periods
- Barking: May bark to alert or when bored
Living Environment
Leonbergers can adapt to various living situations when their needs for space, comfort, and companionship are met.
Ideal Home Setup
- Space: Best suited for homes with ample indoor space and access to a yard
- Secure Fencing: Important for safety and peace of mind
- Indoor Access: Should live indoors as part of the family
- Comfortable Resting: Orthopedic beds to support joints, multiple resting areas
Family Compatibility

- Other Pets: Usually good with other pets when properly introduced
- Seniors: May be suitable for less active households due to calm nature
- First-time Owners: Possible with proper research and commitment to training
Important Considerations
Leonbergers are massive dogs that require proper space and accommodations. Their size means they can accidentally knock over furniture, people, or children. They need sturdy, appropriately sized equipment including beds, bowls, and crates. Potential owners should be prepared for significant shedding, drooling, and substantial food and veterinary costs. Leos are best suited for households where someone is home regularly, as they thrive on companionship. They're sensitive to extreme heat due to their thick double coat and need climate-controlled environments. Their shorter lifespan means owners must be prepared for the heartbreak of losing their companion sooner than with smaller breeds. Always consider the practicalities of transporting a giant breed before acquiring one.

Frequently Asked Questions
Leonbergers can be excellent family pets for the right families. They're typically gentle, patient, and affectionate with children they're raised with. However, their massive size means supervision is essential, especially with young children who could be accidentally knocked over. They form strong bonds with their families and are generally calm and affectionate indoors. Leos are known for their gentle nature and protective instincts, which can make them excellent family guardians. They're best suited for families with adequate space and who can manage their substantial size, shedding, and potential health issues. With proper training, socialization, and care, Leonbergers can be wonderful family companions.
Despite their giant size, Leonbergers have moderate exercise needs. They typically require 45-60 minutes of daily activity, preferably divided into multiple sessions. This should include gentle walks, play sessions, and opportunities for swimming. Leos are not endurance athletes but enjoy regular activity to maintain health and prevent boredom. Puppies should not be over-exercised to protect developing joints. Mental stimulation is also important for this intelligent breed. While they enjoy outdoor time, Leos are generally calm indoors and are content to lounge with their families. Their exercise requirements make them suitable for moderately active households, though they still need regular activity to maintain health.
Leonbergers are not typically aggressive, but they are protective guardians with instincts to defend their family and territory. With proper socialization and training, they learn to distinguish between normal situations and genuine threats. They're generally calm and friendly rather than overtly aggressive. However, their protective nature means they may be wary of strangers and react defensively if they perceive a threat. This is why early and ongoing socialization is crucial. In the hands of inexperienced owners or without proper training, their protective instincts can become problematic. Well-bred Leos should have stable temperaments and be neither shy nor aggressive without cause. Responsible ownership and proper training are essential for well-adjusted behavior.
Leonbergers can adapt to apartment living if their exercise needs are properly met, but they're generally better suited to homes with more space. Their giant size means they need adequate room to move comfortably indoors, and they can accidentally damage furniture or belongings in tight spaces. Additionally, their substantial size can make navigating stairs difficult, especially as they age. While exceptionally well-trained Leos might adapt to apartment life with dedicated owners who provide sufficient exercise and access to outdoor areas, this breed is generally better suited for homes with more space. Apartment dwellers must be committed to providing daily walks and regular trips to parks or other areas where the dog can exercise properly.
Leonbergers typically get along well with other pets, especially when raised with them from puppyhood. Their generally calm and gentle nature makes them good companions for other animals. However, their massive size means interactions should always be supervised, especially with smaller pets who could be accidentally injured. Proper introduction and supervision are essential when adding new pets to the household. Early socialization helps them learn to interact appropriately with other animals. Some Leos may have a higher prey drive and chase smaller animals, so careful management is necessary, particularly with cats or other small pets. With proper training and socialization, most Leos live happily with other animals, but their interactions should always be monitored.
The average lifespan of a Leonberger is 7-10 years, which is typical for giant breeds but shorter than smaller dogs. With excellent care, some individuals may live slightly longer, but it's uncommon for Leos to reach 10 years. Factors that influence lifespan include genetics, diet, exercise, preventive veterinary care, and management of breed-specific health issues. Providing a healthy lifestyle with proper weight management, regular veterinary check-ups, attention to joint health, and prompt treatment of any health concerns can help ensure your Leonberger lives a long, healthy life. Be aware that like all giant breeds, they can be prone to certain health conditions like joint dysplasia, cardiac issues, and bloat that can affect quality of life and longevity.
Leonbergers are intelligent and generally eager to please, but they can be stubborn and independent thinkers. They respond best to positive reinforcement training, patience, and consistency. Their intelligence means they learn quickly but may challenge commands that don't seem purposeful to them. Early socialization and obedience training are crucial. Their independent thinking means they may not always obey immediately, especially if they perceive a more pressing guardian duty. Training requires patience, consistency, and an understanding of the breed's characteristics. They're best suited for owners who can provide confident, gentle leadership. While not the easiest breed to train, they're certainly trainable with the right approach and dedication.
Leonbergers can be challenging for first-time dog owners due to their massive size, strength, potential health issues, and substantial costs. Their size alone makes them difficult to manage for inexperienced owners. However, their generally calm temperament and moderate exercise needs can make them more manageable than some other large breeds. A dedicated first-time owner who does thorough research, works with experienced trainers, commits to proper socialization, and is prepared for the financial responsibility could potentially succeed with a Leonberger. That said, most experts recommend starting with a less challenging breed. If a first-time owner chooses a Leonberger, professional training classes, mentorship from experienced owners, and careful selection from a reputable breeder are highly recommended.
Bottom Line: Is a Leonberger Right for You?
The Leonberger is a magnificent giant breed with a fascinating history and remarkably gentle, devoted nature. These gentle lions combine impressive size with intelligence and versatility that belies their formidable appearance. However, they're not the right choice for everyone. Their massive size, substantial costs, potential health issues, and shorter lifespan require committed, prepared owners. They thrive in homes with adequate space and families who understand and respect their giant breed needs. If you're prepared for the challenges of owning a gentle giant and can provide the necessary training, proper healthcare, and loving environment, a Leonberger might be your perfect companion. This noble breed rewards dedicated owners with unwavering loyalty, gentle affection, and a majestic presence that commands respect and admiration.
