Named for the German town of Leonberg, whose crest bears a lion, the Leonberger was developed in the nineteenth century from crosses that included Newfoundland, Saint Bernard-type and Great Pyrenees dogs. The aim was an imposing, lion-like companion, and the result is a giant with a thick, water-resistant double coat, a mane on many males, a black mask and colors from sand to lion yellow and red-brown. The breed nearly disappeared during both world wars before being rebuilt from a handful of survivors.
Many Leonbergers are gentle, calm and deeply attached to their families, with a steady tolerance for children and household noise. Their size is the main challenge: they need training from puppyhood, room to move, heavy grooming and a budget for giant-breed food and care. Adopters should also expect a fairly short lifespan and some serious inherited health risks.
