SOURCE: "The Hound of Pedro" by Robert Bloch (Weird Tales, November 1938)

DESCRIPTION: "...The hound was silent, ghastly silent; it did not growl or bay, instead it turned and rose. On two hind legs it stood, in monstrous simulation of humanity; then it turned and raced up the stairs in frantic flight..."

PLOT: Black Pedro Dominguez comes to a small Spanish village with his wizard and dog in tow. They have come to take the gold from the mine. They sacrifice virgins to their master, Satan. Don Manuel Digron comes with his men and kill the wizard and the dog. Before the dog dies it speaks. Digron realizes that Black Pedro's soul had been traded with the dog's.

WEREWOLF FACTS: Not many details on shape-shifting outside of the ritual which is used to transfer the soul and that the dog is killed with an ordinary sword.

INTERESTING FACTS: Robert Bloch wrote many tales for Weird Tales, a few which feature werewolves and shape-changers. This one is unusual because of its Spanish setting.
