C is for Cù Sìth.

The Cù Sìth or Faery Dogs play important roles in most of my stories. Most of my heroines have an important task to perform in the future of Faerie – and that makes them targets for the bad guys. So they have a Cù Sìth protector.

Here is the definition of the Cù Sìth for my Faerie world. (It can also be found in the page above about the origin of the Fae along with fun facts about other Fae.)

Cù Sìth

Faery dog in Scottish Mythology that is usually in the form of a big black-and-tan dog (Rottweiler).

They have amber coloured eyes that burn brightly as they do magic.

They protect those of the Mist – humans with magical ability who are important to the Fae Monarchs and children of both worlds (half Fae and half mortal).

They use mindspeak (a form of telepathy) to communicate and all of them speak without contractions – except modern-day Saphira.

The Cù Sìth are the most powerful of all Fae. They control the very fabric of time and space. They create the Faery circles that are the most powerful and accurate of all magical teleportation. They can go anywhere in Time to correct or interfere in someone’s life.

Whenever the Cù Sìth protect someone, all who know about them know that the person who is protected is something special.


I give all my Cù Sìth gemstone names (or I’ll name them after my Rottweilers). <grin>

The Cù Sìth Saphira (who has her own series The Adventures of Saphira the Faery Dog) also happens to be the sister of the Alpha of the Cù Sìth. Fun interactions between them and how Saphira lost the chance to be Alpha herself makes up part of the plot of the series of short stories available on Wattpad.

Cù Sìth from across the web.

The Cù-Sith (Scottish Gaelic pronunciation: [kuː ʃiː]), plural Coin-Sìth (Scottish Gaelic pronunciation: [kɔːn ʃiː]) is a mythological hound found in Scotland and the Hebrides. A similar creature exists in Irish folklore (spelled Cú Sídhe), and it also bears some resemblance to the Welsh Cŵn Annwn.


According to Scottish folklore, the Cù-Sìth is said to be the size of a young bull with the appearance of a wolf. Its fur is shaggy, and usually cited as being dark green though sometimes white. Its tail is described as being long and either coiled up or plaited (braided). Its paws are described as being the width of a man’s hand.[1]

The Cù-Sìth is thought to make its home in the clefts of rocks in the Highlands,[2] and also to roam the moors and highlands.


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. In this role the Cù-Sìth holds in Scottish folklore a function similar to that of the Bean Sidhe, or banshee, in Irish folklore.

According to legend, the creature was capable of hunting silently, but would occasionally let out three terrifying bays, and only three, that could be heard for miles by those listening for it, even far out at sea. Those who hear the baying of the Cù-Sìth must reach safety by the third bark or be overcome with terror to the point of death.[2]

It was also said the baying was a warning to lock up nursing women lest the beast abduct them and take them to a fairy mound (Scottish Gaelic: sìthean, pl. sìtheanan) to supply milk for the Sith (daoine sìth).





Cu Sith – Literally translates to fairy dog, this is the Highland equivalent.  In appearance the dog was green with long shaggy fur, it was roughly the size of large calf and not unusually it was considered dangerous to meet.

The creature was capable of hunting in silence, and would let out three barks, which could be heard from miles around.

Supernatural dogs are usually completely black or white with red ears, this is the only example of a green dog although green is the colour of the fairies.
