A dog is seen leaping ashore from the Demeter in Dracula.
The Demeter is the ship carrying Count Dracula and his boxes of Transylvanian earth to England. Its captain’s log records the crew disappearing one by one during the voyage. When the ship finally runs aground at Whitby, witnesses see a large dog leap from the vessel and run up toward the churchyard.
The animal is Dracula in one of his transformed forms, or at least the novel strongly connects the apparition with his arrival. Earlier in the story, Dracula’s supernatural abilities include taking the forms of a bat, wolf, and mist. The dog at Whitby creates a memorable bridge between the mysterious sea voyage and the Count’s attacks on land.
Readers sometimes answer “wolf” because wolves are closely associated with Dracula and appear elsewhere in the novel. The Whitby landing scene, however, specifically describes a large dog. Later adaptations may alter the animal’s appearance, but the canonical answer for Stoker’s novel is dog.
