…his great hound. The only creature that is allowed to enter the master chamber of the mansion is the hound.
What does it say about the owner? That he is an introvert, a closed off person that does not allow anyone to get close to him. He believes he can manage everything by himself, that no one can do anything better than him.
Dogs are faithful and grateful. They stay with you till their last hour. They will help you and listen to your word without any qualms.
The hound is his best friend, his only friend. For truly he needs none.
