What is the name of the dog monster? - in detail

In Greek mythology, the most well-known "dog monster" is Cerberus. This three-headed hound was said to guard the gates of Hades, the underworld realm of the dead. Each head had a distinct role: one looked toward the past, another toward the present, and the third toward the future. Cerberus was not merely a beast but a symbol of transition and the unyielding nature of death's domain. His formidable presence underscored the seriousness of crossing into the afterlife, ensuring that no soul could escape without proper authorization. This mythical creature has been depicted in various forms of art throughout history, reflecting different cultural interpretations while maintaining its core significance as the watchdog of the underworld.
