My poor stupid dog

Yesterday some car knocked down my poor dog. I know he's too energetic and kinda naive and stupid. He had been bitten several times badly by dogs, know he is even being knocked by a car. Now he lies all poor and pitiful near his dog house. We had him operated yesterday. They said he'll be all right. But who knows, especially when he continues do the same...

Here's his pic from when he was injured last time.
