Spectral black dog either guides or misleads travelers

Gwyllgi

In certain accounts, it appears to lost travelers, not to harm them, but to guide them safely home.

Kludde

Kludde is a shapeshifting demon of Flemish and Belgian folklore, haunting roads, hedgerows, and waterways in the guise of a black dog, horse, or other beast. Kludde is a shapeshifting demon or bogey of Flemish and wider Belgian folklore, bound in most tellings to a particular stretch of countryside — a hedge, thicket, or bend of road — rather than to any fixed dwelling, and said in some accounts to keep to that ground even when the hedge itself is moved or replanted.

Plat-Eye

Gullah and broader Lowcountry tradition along the South Carolina and Georgia coast tells of the Plat-Eye, a night-haunt most often described as a large black dog whose eyes begin small and swell alarmingly as it draws near a traveller.

Black Dog

Despite its fearsome reputation, there are also tales of Black Dogs protecting travelers or warning of danger, suggesting a complex and ambiguous nature that defies simple categorization.

Moddey Dhoo

As with those related but geographically distinct beings, the Moddey Dhoo belongs to a widespread folk pattern in which a large black dog functions as a portent of death or as an actively dangerous guardian spirit attached to a specific haunted site, rather than as a roaming or generalized threat.
