Characteristics and Temperament
The Leonberger is a noble, powerfull yet gentle, dog. They are
warm, big, soft, if necessary protective, companions, perfect for
nestling into or clutching if you are a toddler.
However, Leonbergers are large dogs and are frightening to many people simply by their size. Fear and aggression in a stranger can activate a dog's protective instincts. Huge dogs can also do a great deal of damage just by jumping up on someone in a burst of enthusiasm. When you invite a Leonberger to share your life, you bring to that contract the responsibility to make sure that both you and your dog receive excellent obedience training.
Leonbergers are known for their stability. As a general rule, they are consistently even-tempered and generally pleasing to be around even in noisy and chaotic situations that would be highly stressful for some other breeds. A typical and impressive sight at dog shows and gatherings is a large "pride" of Leonbergers peacefully and contentedly sitting and lying together in close quarters.
Leonbergers are excellent watchdogs, not given to frivolous barking or unnecessary alarms. Their imposing size and deep bark are usually enough to deter uninvited guests. They instinctively establish and maintain their household's territorial rights. However, upon receiving the OK from family members, strangers are accepted and welcomed.
