George has a clever dog calling Leonard. He often lets it play outside by himself. He never thought something will happen to it because it didn’t hurt anyone.

One day, it went out to play and it didn’t return back home at the usual time. George felt so worriedly that he looked for it everywhere it might go. Ten minute later George found it lay on the ground with an arrow in its stomach. So George rushed it to the hospital. Luckily it survived.

Later George discovered arrow was tied with a note, that said “A disturbing dog is unbearable and its death is not to be regretted”. What a pity to treat our pet friends like that!
