What is a three headed dog called in Greece?

Answer 1

In Greek mythology, a three-headed dog is called Cerberus. He is known as the guardian of the Underworld, preventing the dead from leaving and the living from entering without permission. Cerberus is often depicted as a fearsome creature with three heads, a serpent's tail, and sometimes additional snakes on his back. He is famously associated with the hero Heracles, who was tasked with capturing him as one of his Twelve Labors.
