The breed is bold, determined and self-reliant. It is usually calm and loyal with its own people but reserved with strangers, and it can be sharp with other dogs. In North America, Karelian Bear Dogs have been used in wildlife management to chase black and grizzly bears away from towns and campsites, a practice known as bear shepherding.
The dog is a sturdy, well-boned spitz with a head shaped like a blunt wedge, medium-sized pricked ears and a tail curled over the back. The coat is straight and harsh over a dense undercoat. It is black, often with a slightly brownish or dull tinge, and most have clear white markings on the head, neck, chest, belly and legs.
The Karelian Bear Dog, known in Finland as the Karjalankarhukoira, was still a young breed when the Second World War disrupted its development, and numbers fell sharply during the conflicts with the Soviet Union. Finnish breeders rebuilt it afterwards from the dogs that remained, and it settled into steady use among hunters, chiefly for elk rather than bear. Its work is to range silently and widely through forest, find large game and then bark persistently to hold the animal in place until the hunter arrives.
