Temperament & character

The Leonberger is friendly, self-assured, and family-oriented, showing friendly reserve rather than suspicion toward strangers. Despite its size, it is considered biddable and rarely aggressive.

Exercise & stimulation

Exercise needs are moderate; long walks are enough, while excessive jumping or stair climbing should be avoided during growth. As a giant breed, it needs slow, controlled growth without overloading the joints as a puppy.

Grooming

The dense, weatherproof coat needs brushing several times a week, daily during shedding periods. Because of its size, regular weight checks are important to avoid placing extra strain on the joints.

Suitable for beginners?

Size and weight call for consistent leash training from the start and enough space at home and in the car. Keeping the breed is demanding for first-time owners without experience with giant breeds.

Health & common problems

Breed-typical conditions include hip and elbow dysplasia, osteosarcoma, and Leonberger polyneuropathy, an inherited nerve disease. A genetic test for polyneuropathy and slow growth as a puppy are recommended.

Good with: Experienced owners with plenty of space
