The Leonberger is a lush-coated giant of German origin. They have a gentle nature and serene patience and they relish the companionship of the whole family.


Don’t let his size and lion-like looks fool you; the Leonberger is a big bundle of love. Bred as farm dogs and family companions, Leonbergers are eager to please and, with their love of children, are wonderful family dogs. Because they respond so well to training, they also make excellent therapy dogs. Leonberger puppies grow up to be surprisingly graceful adult dogs, who will appreciate moderate exercise and some regular training. They are shedders, so you’ll want to brush that double coat regularly.

About the Leonberger

A huge and powerful dog, yes, but the Leonberger is also known for his aristocratic grace and elegance. A male can stand over 31 inches at the shoulder and weigh as much as a full-grown human. Females run smaller but are still a whole lot of dog. Breed hallmarks include a medium-long waterproof coat, lush triangular ears, a bushy tail, and a black face-mask that frames kindly dark-brown eyes. A dramatic feature of the male’s coat is the lion-like mane around the neck and chest. A well-built Leo moves with an easy, elastic gait. A Leo is friendly but nobody’s fool. As watchdogs and all-around workers, they exhibit intelligence and sound judgement. Leos require lots of brushing, ample room for romping, and unlimited love.

NUTRITION The Leonberger should do well on a high-quality dog food, whether commercially manufactured or home-prepared with your veterinarian’s supervision and approval. Any diet should be appropriate to the dog’s age (puppy, adult, or senior). Some dogs are prone to getting overweight, so watch your dog’s calorie consumption and weight level. Treats can be an important aid in training, but giving too many can cause obesity. Learn about which human foods are safe for dogs, and which are not. Check with your vet if you have any concerns about your dog’s weight or diet. Clean, fresh water should be available at all times.

GROOMING Leonbergers shed a lot—and twice a year, they shed even more. A Leo should be brushed every day, especially in the areas of his body that tend to mat: the long hair behind the ears and on the backs of the legs. A more thorough grooming should be done once a week—and given the breed’s size, this will take a fair amount of time. Leos have a thick, full outer coat and a shorter, fluffier undercoat. A metal comb and an undercoat rake can be used to work out the undercoat, and a pin brush and a slicker brush will neaten up the outer coat. In addition, a Leo’s nails-should be trimmed every other week.

EXERCISE If you live in a city apartment or a house on a small, suburban lot, this may not be the breed for you. Adult Leonbergers are generally calm and subdued, but they still need to have some vigorous exercise once a day. Puppies and adolescents are active and exuberant. Adult dogs can benefit from jogging or hiking with their owner or keeping pace alongside a bicycle. A large yard with a tall, strong fence is the ideal place for a Leo to run around. Remember, these are working dogs. Drafting—that is, pulling a cart—and agility training are two good ways for a Leo to get the activity he or she needs.

TRAINING Leonbergers are very large and strong. In addition, puppies and adolescents have loads of energy and are extremely enthusiastic. With these facts in mind, proper training of the breed is essential. Leo puppies should be socialise by being gently exposed to a wide range of people, animals, and settings before the age of 20 weeks. Group obedience classes will help a Leo learn to be a well-mannered companion and canine citizen. A Leo is probably stronger than and may even outweigh his owner, and it is imperative that he learns to do what you want him to do.

HEALTH As with all canines, proper exercise and nutrition, routine vet exams, and parasite prevention are keys to a happy and healthy life. Large dogs such as Leos can experience bloat, where the stomach twists and gas is trapped inside. Bloat can quickly be fatal, and it is important to know its signs, such as drooling, restlessness, enlarged abdomen, and attempts to vomit. Owners of at-risk dogs can consider the preventative measure of having their dog’s stomach surgically tacked to the abdominal wall.
