My brother was just part of a genetical experiment that was supposed to make him have the behaviour of a dog. It is irreversible. We are in the car now driving home, and he is curled up in the back seat sleeping. Whenever I tap him, I won't do anything. I already bought everything for his appearance, like a prosthetic tail, and canine teeth. I don't want him to attack me if he does wake up. What do I do?
