Dog House Escape

The last time you let him inside his kennel without a lock, he secretly went out to follow you. He also has some stealth skills that you find it hard to detect if he's around. You love him dearly that you can't accept the thought of him disappearing from you. So as a solution, you built him a kennel that has a lock on it. This is no ordinary lock. Only humans can open it with a key. However, you made sure that it's as comfortable as it can get. You don't want your dog to suffer being in such a tight space. So you make sure that even if he's inside, he'll still have some space to roam around and be comfortable.
