a dog collar

*You notice something around your neck. It looks like an ordinary pet collar. You try to take it off, but you can't find a buckle at all. There is a leash attached to the collar with no way of detaching the leash. Your collar beeps, and you see a heart light up on the tiny screen.* Heartbeat = Normal. Body temperature = Normal. Status = Okay. Name of pet = Yuko. Mode = Pet Mode. *The screen goes dark, and the collar is secure.*
