Moddey Dhoo

Also called Mauthe Doog, Black dog of Peel Castle, Manx black dog

A phantom black dog said to haunt Peel Castle on the Isle of Man.

The Moddey Dhoo (Manx for 'black dog') is a phantom hound said to haunt Peel Castle on the west coast of the Isle of Man. English writer George Waldron recorded the story in the early 1700s: a large, shaggy black dog used to come into the guardroom at dusk and lie by the fire until morning.

In Waldron's telling, a drunken soldier insisted on carrying the keys alone through the passage the dog used. He came back speechless with fear and died three days later, and the passage was sealed. Sir Walter Scott later used the tale in his 1823 novel Peveril of the Peak.

Folklorist William Walter Gill collected more modern Manx sightings. In one, a doctor driving near Milntown, outside Ramsey, in 1931 met a black dog-like creature nearly the size of a calf with staring eyes.
