Rocky is the name of the dog that Ghost looks after.
Appearance[]
The dog is grey and has an uncanny similarity to the werewolf that stalks Brigitte, with its grey fur and sharp snout.
Significance[]
Rocky's death leads Brigitte to realize that the death must have been caused by the Beast, a werewolf which, as from what the events of Ginger Snaps suggest with another werewolf named the Beast of Bailey Downs, has a liking to murder dogs.
