Leonberger Dog Breed

Leonbergers make excellent family dogs and many form close bonds with children in their household.

Because of their size, even a friendly nudge can knock over a small child. An adolescent Leonberger may be too much for very young children to cope with. Interactions between this breed and children should be closely supervised. Leonbergers need lots of space to move around comfortably, so a home with a reasonably sized garden suits them well. This is a giant breed, so their lifespan is shorter than smaller dogs. This is worth thinking about carefully if you have young children. 

Leonbergers need a home with plenty of indoor and outdoor space to suit their giant size. A reasonably large, secure garden is a real benefit for this breed.

This breed suits families who can dedicate time to training, exercise, and grooming. All three are big commitments with a Leonberger. They are generally good with children and other pets when properly socialised. Their size means supervision is important, especially around toddlers.

Leonbergers are not well suited to small flats or homes that are often empty. They need company and room to move. 

Leonbergers are deeply affectionate with their family and enjoy being close to their people. Many like to lean against their owners or settle nearby rather than in another room.

This breed can be a little reserved with strangers at first, but most warm-up once they get to know someone. Leonbergers form strong attachments to their family and struggle being on their own for long periods. Time-alone training from puppyhood helps this breed cope when left by themselves.  

Leonbergers enjoy play, especially gentle games with their family. Many prefer calm activities over rough-and-tumble activities.

Many Leonbergers enjoy water-based activities. This reflects their history as water rescue dogs. Retrieving games and swimming are great outlets for their energy. Puzzle toys and simple training games also help with mental exercise. Because of their calm nature, most Leonbergers are just as happy relaxing at home as they are playing. 

Leonbergers don't bark excessively, but they do have a deep sounding bark which can be intimidating to visitors. Many will bark to let their family know when someone's at the door or an unusual noise.

They're not typically prone to nuisance barking if their needs are met. Boredom or a lack of exercise can lead to more barking in some dogs. Reward-based training and regular exercise usually help keep barking at a manageable level. 

Any breed or crossbreed can develop behaviour issues if their needs are not met. For Leonbergers, their size is a key factor. Unwanted behaviours like jumping up or pulling on the lead needs to be managed early on. If not, this behaviour can be a real challenge.

Early and ongoing socialisation and habituation helps Leonbergers cope with new people, other dogs, and busy places. Without enough mental exercise, some Leonbergers get bored. This can cause chewing or other destructive behaviour. If training or behaviour feels hard, call our free advice line for support. 

Leonbergers need a good amount of daily exercise of at least one hour. It should include walks, free running, and other activities like swimming.

This breed's joints keep developing well into their second year, so exercise should be gradually worked up in puppyhood. This helps to protect their growing bones and joints.

Leonbergers also benefit from mental exercise through training games and simple tasks. This reflects their history as versatile working dogs. Without enough exercise, this breed can get bored or put on excess weight. This places extra strain on their joints. 

Leonbergers are generally easy to train with positive, reward-based methods. They are intelligent and eager to please their family.

Leonbergers grow into a large, powerful dog. Early training and socialisation matter a lot because of this. Training should ideally start as soon as a puppy comes home. Good manners around greeting people and walking on a lead matter more with a giant breed than a smaller one. This is simply because of their size and strength.  Training should continue from a puppy all the way through adolescence to help this breed grow into a well-mannered adult.

Leonbergers have a thick, water-resistant double coat. It sheds throughout the year, with heavier shedding in spring and autumn. Brushing two to three times a week helps manage loose fur and prevent matting.

During shedding season, daily brushing is often needed to keep on top of loose hair. A slicker brush and an undercoat rake both help remove dead fur from the dense undercoat.

Many owners find professional grooming helpful for this breed, given the size of the coat. Regular grooming sessions are a good chance to check for lumps, cuts, or parasites. Nail trimming and ear checks matter too. 

Leonbergers average lifespan is shorter than smaller dogs, typically around seven to nine years. As with all pedigree dogs, it's important to choose a breeder who tests their breeding dogs for health problems.

Health conditions that can affect this breed include:

• Hip and elbow dysplasia – the joints do not form properly. This can lead to arthritis and discomfort.

• Dilated cardiomyopathy – a heart condition that weakens the heart muscle. Regular cardiac checks usually pick this up.

• Leonberger polyneuropathy – an inherited condition affecting the nerves and muscles. It can cause weakness or trouble walking.

• Cancer, including bone cancer – giant breeds have a higher risk of certain cancers than smaller dogs.

This is a deep-chested breed. Leonbergers are also at high risk of bloat, a life-threatening emergency that needs immediate vet care. Regular vet check-ups, a healthy weight, and the right exercise all help support this breed's wellbeing.
