Gytrash

The Gytrash ( /ɡaɪˈtræʃ/), a legendary black dog known in northern England, was said to haunt lonely roads awaiting travellers. Appearing in the shape of horses, mules, or dogs, the Gytrash haunt solitary ways and lead people astray. They are usually feared, but they can also be benevolent, guiding lost travellers to the right road.
