This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Cadejo (Central America)
The cadejo appears as a dog-shaped creature with blue eyes when it is calm and red eyes when it is attacking. It roams around isolated roads at night, according to Central American folklore of indigenous origin. The term cadejo is thought to have derived from the Spanish word cadena, meaning "chain"; the cadejo is at times represented as dragging a chain behind him.
The cadejo ranges in size, according to different tales in various regions. It lurks in graveyards and dark alleys, waiting to attack a passing victim. It has a distinctive smell of concentrated urine and burning sulphur. It rattles with a jerking motion, contracting its pharynx. Its gaze freezes anyone who makes eye contact. Its skin and short hair, similar to those of a pig, glitter in the pitch dark.
