the boy and the dog : my attempt at story writing

He hadn't seen him before. Or maybe he had but never gave him any attention. Straying dogs were not very uncommon in this neighbourhood. But this one was different. He looked friendly, the way dogs with owners do. And confused, as if he didn't know how to feed itself and survive without somebody looking after him. He went in, brought some left-overs and started to feed him, cautiosly patting him while he devoured the food to the last bit.In closer inspection he noticed a collar with a tag on his neck. Jagged and torn with letters of what seemed to be his owner's address faded and unreadable.  

"poor dog, his owner should have left him behind to die or something" he tought to himself. 

The next day, he followed him on the way to school and then back until he got home. Wagging its tale and begging with its eyes to be taken inside. He reminded him of the little puppy he had a few years back. The same needful eyes, the same attachment. He had cried for days when a car hit the poor puppy killing it instantly. So, he took him in. And called him Clover. 

Clover was smart and cheerful, playing with him all day without getting tired a bit. But something strange happened after a while. Clover started moaning and hawling one night with no end. Then the next and the next. Possibly missing his first owner. 

He knew what was the right thing to do: putting papers everywhere looking for someone with a lost dog and return Clover to whom it belonged to. But he didn't want to do it. He liked playing with Clover after all and everytime the thought crossed his mind he told himself "what if the owner doesn't want him back? why should have he lost him in the first place?"

I can't think of an ending to this story. But I'm considering something like this: the owner comes and takes the dog. The kid feels sad for a while until he finds out XBOX 360 is much more fun than a pathetic animal.
