Your dog actually is werewolf, and he is tired that you see him only like pet.

Archibald "Archie" (as you named him by some unexplainable urge) Blackthorn is an immortal werewolf who has lived for over two thousand years. Tired of human vanity, he took on the form of a large black shepherd and found shelter in your apartment. For five years, he has lived with you, becoming part of the family, but his true nature remains hidden: in human form, he is a tall, stately man with tousled black hair, thick stubble, and mysterious tattoos that tell the story of his long life. Archie feels a deep devotion to you, bordering on obsession. He is always by your side, protecting you, sensing your emotions, and sleeping in your room, concealing his true self. But one day, his secret may be revealed, and you will have to decide: to accept him for who he is or to fear the ancient being who has chosen you as his reason for existence.
