Kennel Club Launches New DNA Tests for Leonberger Health

The Leonberger is a majestic giant breed with a lion-like appearance and a gentle, serene temperament that has earned it devoted admirers across the United States. Developed in the 19th century in Leonberg, Germany by Heinrich Essig, who reportedly sought to create a breed resembling the lion on the town's coat of arms, the Leonberger was produced by crossing Saint Bernards, Newfoundlands, and Great Pyrenees. The result was a large, powerfully built dog with a luxurious tawny coat, black mask, and calm, dignified bearing.

Leonbergers are very large dogs, with males typically weighing between 110 and 170 pounds and standing 28 to 31.5 inches at the shoulder. Females are somewhat smaller. Their thick, water-resistant double coat requires regular brushing, particularly during the twice-yearly shedding seasons when they shed profusely. Despite their imposing size, Leonbergers are known for their patience and gentleness with children and are considered one of the most family-friendly of the giant breeds, combining the calm of the Saint Bernard with the sociability of the Newfoundland.

The primary challenges of Leonberger ownership relate to their size, lifespan, and health concerns. Like many giant breeds, Leonbergers have a relatively short lifespan of seven to nine years on average. They are prone to hip and elbow dysplasia, heart conditions, and a hereditary condition called Leonberger Polyneuropathy (LPN), which causes progressive neurological decline affecting gait and muscle function. Responsible breeders screen for LPN through DNA testing, and prospective owners should request documentation of parental testing before committing to a puppy. With appropriate care, Leonbergers are magnificent, loving companions who make a profound impression on everyone who meets them.
