The Cù Sìth of Scottish mythology is an enormous, otherworldly hound, said to haunt the Scottish Highlands. Roughly the size of a cow or large calf, the Cù Sìth was said to be dark green in color with shaggy fur and a long braided or curled tail. In Irish mythology, the Cù Sìth was said to be an immense, coal-black hound with glowing or flaming eyes. The Cù Sìth was feared as a harbinger of death and would appear to bear away the soul of a person to the afterlife (similar to the manner of the Grim Reaper).
