Cerberus (1824–7)

You probably wouldn’t want to pat this dog on the head. For a start you’d need to decide which head to pat! Meet Cerberus the three headed dog that, in Greek mythology, guards the gates of the underworld. If you’re a fan of Harry Potter this monster mutt may seem familiar. The character (rather disconcertingly) known as Fluffy, the fierce three-headed dog that guards the magical philosopher’s stone, is based on Cerberus.
