Are there examples of the myth of Cerberus?

The final labor of Heracles was to bring Kerberos (Cerberus), the guard of the underworld, to the court of Eurystheus. Smartly, Heracles asked Hades for permission to remove the guard from his post, to which Hades agreed, on the condition Heracles used no weapons. Heracles overpowered the beast, slung him over his shoulder and dragged him from the underworld. Eurystheus was so afraid that he jumped into a jar and stayed there until Heracles removed the beast.
