The Leonberger is a lush-coated giant of German origin with a gentle nature and serene patience — a large, muscular, yet elegant dog distinguished by its black mask, substantial bone, balanced build, and double coat. They relish the companionship of the whole family.
Intelligent and lively, friendly yet vigilant, the Leonberger is attentive and self-assured in all situations. Temperamentally more akin to a cuddly teddy bear than the aloof lion that was supposedly their inspiration, they are gentle and playful in proportion to their formidable size.
The Lion of the Town Crest
The Leonberger breed name derives from the city of Leonberg, in Baden-Württemberg, Germany. The legend is that the dogs were bred to be an homage to the lion — the coat-of-arms animal of Leonberg — and the breed lore says that noble beast inspired this shaggy-coated, regal dog, which soon became a must-have among the well-heeled.
In the 1830s, Heinrich Essig, a dog breeder, seller, and city councilor of Leonberg, claimed to have created the Leonberger by crossing a female Landseer Newfoundland with a male from the Great St Bernard Hospice and Monastery, reportedly later adding a dose of Great Pyrenees. The first dogs registered as Leonbergers were born in 1846, which is generally accepted as the year the breed was founded.
The Leonberger became popular with several European royal households, including Napoleon II, Empress Elisabeth of Austria, the Prince of Wales, Otto Von Bismarck, and Emperor Napoleon III. In the early years, Essig tried to produce white dogs because they were popular; it wasn't until after his death in 1899 that the tawny, lion-colored coat with mane and signature black mask became fixed and indelibly associated with the breed.
Essig bred for one trait that is universal in the breed even to this day — an affectionate, stable temperament that proves irresistible to everyone they meet. Only five Leonbergers survived World War I, and during the two world wars Leonbergers were used to pull ammunition carts, resulting in near-destruction. Karl Stadelmann and Otto Josenhans are credited as the breed's saviors, and Leonbergers today can trace their ancestry to the eight dogs that survived World War II.
A Large, Muscular, and Elegant Dog
The Leonberger is a large, sociable working dog, muscular yet elegant, with a proud head carriage. An adult male is 28 to 31.5 inches in height (30 inches preferred), and an adult female is 25.5 to 29.5 inches (27.5 preferred). Males weigh 120–170 lb, females 100–135 lb. Height to length of body is 9:10, and depth of chest is 50 percent of the height.
The head is adorned with a striking black mask, and adult males are particularly powerful with a lion-like mane on the neck and chest. The breed has webbed paws and a thick, dense, water-resistant double coat of medium to long length. The coat may be yellow, red, reddish brown, or sandy, including all combinations in between, always with a black mask. Despite its imposing size, the Leonberger is graceful in motion with a ground-covering, even, and balanced gait.
Confident, Gentle, and Playful
The gentle character and even temperament of the Leonberger is of utmost importance for its role as a family companion. Confident, with a steady, playful demeanor, the breed is willing to please and possesses a good capacity for learning. Well socialized and trained, the Leonberger is self-assured, insensitive to noise, submissive to family members, friendly toward children, well composed with passersby, and self-disciplined when protecting its family or property.
Robust, loyal, intelligent, playful, and kindly, Leonbergers can be taken anywhere without difficulty and adjust easily to a variety of circumstances. They are great with children, amenable to other dogs, and welcoming to strangers when well-socialized. They love to play but don't mind being a couch potato either — and they want and need a lot of affection from everyone in their family.
Exercise and Activity
The Leonberger is generally calm and quiet but requires brisk exercise at least once every day, such as a long walk or hike. True to the breed's origins as a multipurpose family, farm, and draft dog, today's Leonberger excels as a versatile working dog — pulling sleds, swimming, agility training, and working in search and rescue, particularly in water.
| Dog | Daily exercise | Notes |
|---|---|---|
| Puppy | 3–4 short play sessions of 10–15 minutes | Keep walks gentle; avoid hard surfaces while growing |
| Adult | 30–45 minutes total walk or play | Split into two shorter sessions if preferred |
| Senior | 20–30 minutes of gentle walking | Slow the pace and shorten distance with age |

Training a Leonberger
Leonbergers are intelligent, easy to train, and prefer to have a job to focus on. Proper control and early socialization and training are essential, as this is a giant breed. They are willing to please with a good capacity for learning, and respond best to positive, consistent training.
The Dog Training Guide and Puppy Care Guide offer a solid foundation.
Grooming a Leonberger
Leonbergers require a great deal of grooming due to their dense double coat. They shed persistently throughout the year, with even heavier shedding periods twice a year, so a committed family that grooms thoroughly and frequently is essential. The long, profuse outer coat is durable and relatively straight, presented untrimmed apart from a neatening of the feet.
| Task | Frequency | Notes |
|---|---|---|
| Brushing | 3–4 times a week | Brush in the direction of the coat and check for tangles |
| Bathing | Every 6–8 weeks or as needed | Use a mild dog shampoo |
| Nail trimming | Every 3–4 weeks | Trim when you hear nails clicking on the floor |
| Ear checks | Weekly | Look for wax, redness, or odor |
| Teeth brushing | 2–3 times a week | Dental chews help as a supplement |
| Professional trim or clip | Every 6–8 weeks | Keeps the coat tidy and hygienic |

Feeding a Leonberger
A Leonberger should be fed high-quality food appropriate to its age, size, and activity level, typically in two meals per day. Giant-breed dogs such as the Leonberger are prone to obesity, which can worsen arthritis, so monitoring calories and body condition is very important.
| Life stage | Meals per day | Portion per meal (approx.) | Notes |
|---|---|---|---|
| Puppy (under 6 months) | 3–4 meals | 1.5–2 cups | Use a large-breed puppy formula |
| Adult | 2 meals | 3–4 cups | Adjust to activity level and body condition |
| Senior (7+ years) | 2 meals | 2.5–3.5 cups | Consider a senior or joint-support formula |
Your veterinarian can recommend the right diet and portions.
Health and Veterinary Care
The Leonberger has a shorter life expectancy than average — around 7 to 10 years — due to its giant size, and is prone to certain conditions. An analysis found almost half suffered from at least one health condition; the most common were arthritis, polyneuropathy, hypothyroidism, gastric torsion (bloat), and dilated cardiomyopathy. Choosing a responsible breeder who screens for these is essential.
| Check-up | Frequency | Notes |
|---|---|---|
| Wellness exam | Annual | Includes dental and weight check |
| Vaccinations | Annual booster | Follow your veterinarian's schedule |
| Heartworm prevention | Monthly (or as advised) | Year-round in most regions |
| Dental check | Annual cleaning as recommended | Watch for tartar buildup |
| Hip/elbow dysplasia and bloat awareness | Discuss with your vet | OFA/PennHIP on parents |
| Senior wellness checks | Start from age 5–6 | Early detection of age-related conditions |

Home Environment
The perfect home for a Leonberger is one with a loving, attentive family willing to exercise and groom their dog daily. They do well in homes with or without kids and other pets, but the breed is not cut out for city life — this large breed needs a big yard with a strong fence. Leonbergers don't do well when left alone for long periods and would prefer around-the-clock love and attention.

Common Ownership Challenges

Yet for the right owner, the Leonberger is a treasure — a gentle giant with a lion's mane and a heart as big as its body, devoted to its family.
