The cadejo is presented in the literature as a survival of older Mesoamerican beliefs in animal companions, nagualism, and dogs as psychopomps that accompany the dead to the afterlife. Modern Spanish usage applies the name 'cadejo' to this spirit; sources characterise the motif as rooted primarily in Maya mythology and Nahua shamanistic traditions, later syncretized with Christian elements in popular narratives.
Typical accounts depict the cadejo as a large, shaggy, dog‑shaped creature encountered at night. Many descriptions emphasize luminous eyes that are blue when the creature is calm and red when attacking. A common regional distinction presents a large black cadejo with ember‑like red eyes and often dragging heavy chains, and a white cadejo that functions as a protective spirit. Local and literary variants add differing details—goat hooves, jaguar teeth, rabbit ears, bat‑like features, wholly brown coats in some Costa Rican tellings, or a half‑dog half‑man form in Yucatán—indicating significant regional morphological variation in the lore.
Folklore attributes both protective and harmful roles to the cadejo. The white cadejo is said to guard travelers (in some areas specifically protecting drunk people from robbery or harm), while the black cadejo may attack or try to kill nocturnal wayfarers. Narratives claim that turning one’s back on or speaking to a cadejo can induce insanity; attempts to kill a cadejo are said in tradition to fail and to lead to the death of the would‑be slayer, and if a cadejo's corpse is reported it allegedly smells terrible for days before disappearing. Other behaviors include dragging chains, bone‑rattling footsteps, and in some Honduran accounts scavenging on putrefying corpses.
