 There is a good white cadejo and an evil black cadejo.
 Both are spirits that appear at night to travelers: the white to protect them from harm during their journey, the black (sometimes an incarnation of the devil) to kill them.

 In some places, the black cadejo is seen as the good one and the white cadejo the evil one.
 They usually appear in the form of a large (up to the size of a cow), shaggy dog with burning red eyes and a goat's hooves, although in some areas they have more bull-like characteristics.

 It is also said that if a cadejo is killed, it will smell terrible for several days, and then its body will disappear.
