Size and Structure
Leonbergers are large, robust dogs. Males typically stand between 28.5 and 31.5 inches tall at the shoulder and weigh between 119 and 170 pounds; females are slightly smaller, measuring 25.5 to 29.5 inches in height and weighing 88 to 132 pounds. Their bodies are elongated rather than stocky, with strong muscular builds, well-laid-back shoulders, straight legs, and broad, deep chests. Their backs are firm and level, leading to gently sloping croups and broad, rounded rumps. Rounded, strong feet with black pads support their significant mass and endurance.
Coat and Coloration
This breed features a dense double coat with a coarse outer layer and a softer, woolly undercoat, offering excellent water resistance. The coat may display a slight wave and boasts a prominent lion-like mane around the neck and chest, especially in males. Abundant feathering adorns the front legs and hind leg breeches. Acceptable colors include various shades of gold, lion, red, and sandy hues, typically paired with a black mask that enhances the breed's noble expression. Seasonal shedding peaks in spring and fall, necessitating diligent grooming.
Unique Characteristics
The head is proportionate, longer than broad, with a moderate stop and a slightly Roman-shaped black nose. Eyes are medium oval, medium to dark brown, conveying intelligence and kindness. Ears are large, well-feathered, set high, and hang close to the head. The tail is well-feathered, carried straight or with a slight curve, complementing a purposeful, ground-covering gait with a level topline and straight front leg movement.
Gender Differences
Males are generally larger with a more pronounced mane and thicker coat, whereas females have a finer build with less exuberant feathering. Temperamentally, females may show slightly more reserve; both genders share the Leonberger’s hallmark calmness and affectionate nature.
