Samjokgu

Samjokgu, the three-legged dog, is a mythical guardian hound in Korean folklore renowned for its ability to detect and pierce through disguises of evil beings, such as the deceptive gumiho (nine-tailed fox). Often depicted as loyal protectors, these creatures serve as vigilant watchdogs, using their unique three-legged form to swiftly pursue and expose malevolent spirits. In legends, they are sometimes shown working in packs, enhancing their role as collective guardians of villages or households. Their presence symbolizes loyalty and the unmasking of hidden dangers, making them a popular motif in Korean tales of supernatural detection and protection.
