These animals were deemed to have the gift of seeing spectres in a larger measure than the best seers. They are observed to be frightened, or to have their fury raised, without any visible or intelligible cause; they show signs of terror and distress when human eyes can see no cause, and it is part of the Celtic belief in the second sight that this excitement is caused by seeing the taïsh, or shades of the living, in those circumstances, and engaged in those services in which the persons, whose similitude they are, will afterwards be. Dogs bark at night, and when this occurs on clear moonlight nights, they are said in English to “bay the moon.” The Celtic belief does not deny that they often bark at the moon, but it asserts further their clamour arises, as the event afterwards proves, from their seeing the forms of that world, in which fetches and doubles move, the omens of an impending death. Horses are better spectre-seers than even dogs. At places where a violent or sudden death is to occur, they take fright, and no effort of the rider can get them to pass the spot, till at last he has to dismount and lead them past. This is caused by their seeing the “fetch” of the subsequent event, but ordinary people pass it over merely as an “unaccountable fright.” “I have heard,” said a Skyeman, “scores of times the dogs howling before a funeral was to take place in Kilmuir churchyard. It was because they saw the wraiths of the living” (_tàslaich nan daoine beò_). It is a universal Highland belief that certain dogs cry at night when any one in the house is to die. In Lorn, a woman, going with leather to a neighbouring shoemaker, had on her way to cross a wooden bridge thrown over a mountain stream. She was accompanied by a young child, whom she left, while she herself crossed the bridge to leave the parcel of leather on the other side. As she was crossing a second time, leading the child, the stream came down in flood, as mountain streams do, and carried away the bridge. The woman and child were drowned, and their bodies were found further down the stream, at a place where, for fourteen days previously, a grey tailless bitch (_galla chutach ghlas_), belonging to a neighbour, used to go and howl piteously.
