Capable of adapting to various tasks, Leonbergers are more agile than many other giant breed dogs, which adds to their versatility.  They are adept at backpacking, running, agility and, because they have webbing between the toes, swimming.  And they work as enthusiastically as they play, excelling in tracking, carting, therapy work as well as other tasks involving great strength and agility.  In fact, some German and Italian Search-And-Rescue teams use the Leonberger in their work, since the breed has a reputation as a great water-rescue dog.  And when not working, they are equally content to recline quietly with their families in front of the living room hearth.

Leos make fine family companions who are well known for being very affectionate and patient with children and, if properly socialized and raised with them, good with other family pets.
