I'm thinking of placing the air conditioner on top of my puppy.
What could you possibly accomplish by putting an air conditioner on top of a puppy?
I want to punish him for being naughty
You are responsible to train and properly take care of any pets that you have. You are an animal abuser and you do not deserve to have a dog.
I'm going to do it anyway and you are so wrong.
It's cruel to do that to a puppy, and he will not make the connection to his naughtiness anyway. You should try a real training program. Puppies aren't born knowing how to behave.
