Calm, gentle and sweet, the Leonberger excels as a multi-purpose working dog, but its most important task is being a reliable family companion. They are friendly dogs that are willing to please, making them excellent therapy dogs. Despite the breed’s lion-like looks and large size, the Leonberger is actually quite light on its feet and graceful in motion. They can be red, reddish brown, sandy, or yellow brown and always has a black mask.
