A huge and powerful dog, yes, but the Leonberger is also known for his aristocratic grace and elegance. A male can stand over 31 inches at the shoulder and weigh as much as a full-grown human. A dramatic feature of the male’s coat is the lion-like mane around the neck and chest.
Leos were developed first and foremost as companions. The breed was the brainchild of Heinrich Essig, a 19th-century politician and entrepreneur of Leonberg, Germany. Utilizing Saint Bernards and Newfoundlands, among other large working breeds, Essig’s goal was to breed a majestic pet for European royalty—truly a dog fit for a king. Despite their regal beginnings, Leos have long been employed as versatile working dogs on farms, pastures, and waterfronts.
If you live in a city apartment or a house on a small, suburban lot, this may not be the breed for you. Adult Leonbergers are generally calm and subdued, but they still need to have some vigorous exercise once a day. Puppies and adolescents are active and exuberant. Adult dogs can benefit from jogging or hiking with their owner or keeping pace alongside a bicycle. Drafting—that is, pulling a cart—and agility training are two good ways for a Leo to get the activity he or she needs.
Leonbergers are very large and strong. In addition, puppies and adolescents have loads of energy and are extremely enthusiastic. With these facts in mind, proper training of the breed is essential. Leo puppies should be socialized by being gently exposed to a wide range of people, animals, and settings before the age of 20 weeks. Group obedience classes will help a Leo learn to be a well-mannered companion and canine citizen. A Leo is probably stronger than and may even outweigh his owner, and it is imperative that he learns to do what you want him to do.
