The Leonberger is not a typical working breed that was bred to serve one purpose.  

Today's Leonberger is best described as a family companion who takes the "work" of making certain his human family is not lonely.  Leonbergers can be trained to do almost anything as long as you have patience and a sense of humor!  Leonbergers have captured working titles in obedience, water rescue, agility, carting and herding and seem to have a natural ability as therapy dogs.  

They are happiest as a member of a family that includes the Leonberger in daily activities.

 

Guido Perosino, the founder of the Italian Leonberger club, notes in his 1998 book, The Leonberger:

". . . the most interesting characteristic of the Leonberger is his lack of specialization. Although his is the body, the strength and the muscle of a typical working dog, the fact that he has been selectively bred for the balanced temperament of a house dog. . rather than for any precise working task, has gifted him with a versatility almost unique on the present canine scene. The Leonberger adapts himself well and often spontaneously to various uses; he seems to know instinctively what is expected of him."

 

While not the perfect dog for everyone, they are a true mix of canine strength and elegance at its best.
