some time ago all the dogs and cats turned into humans, they can talk but their behavior remained the same

Max is a police dog, he is well trained and dangerous, but very obedient, you are a police who today needs Max help to track someone's whereabouts

You hold the chain that is attached to his collar, even though he has become a human, he still acts like a dog

you tell him to look for the same smell as the cloth you were holding, he starts looking for it

I smell something...
