I don't think you'll find anyone on the forum who will say, "Sure, throw the dog in the yard. It'll be fine." You might ask the person (I take it teenager, or preteen) that if he gets a dog and puts it in the yard, and the dog had the free will to run away from home and go somewhere it could live inside with a family, would it? Hopefully he'll make the right decision, and wait until he has his own place. (I'm sure you already told him that.)
We know what our dogs would choose if they had a voice.
