The Leonberger is a quiet dog with a pleasant personality. When it is properly socialised and trained, this giant dog breed is confident, obedient, friendly and well-behaved. It is also loyal, which makes it a great guard dog, on top of its massive size. However, the Leonberger is an intelligent breed with a bit of a stubborn streak, so training might not be easy. Thus, it is not ideal for first-time dog owners who do not have experience handling a large breed with a higher level of training.
Getting on well with children, the Leonberger has an unusual amount of patience. However, it is best to make sure playtime is well supervised to so the dog does not unnecessarily knock over toddlers. Its massive size can also be a bit scary to small children, so it is preferable to have the Leonberger around older children instead.
When it comes to other dogs, it gets on well with them especially when it has been well socialised at a young age. However, care must be taken when the Leonberger is around small animals as it will not hesitate to give chase.
