the ultimate quarry of the dog as pursuer—the hunting dog—is the ego. Actaeon experienced this when his dogs turned on him… sometimes the ego is going to be hunting with the hounds and sometimes it's going to be running with the fox.
Edinger identifies the hound as a Jungian emblem of the psyche's hunting aspect, whose reversible relationship to the ego — ally or executioner — defines the core psychological dynamic of the symbol.
