After school, I was about to enter into my apartment when I saw a little dirty dog lie beside the dustbin. He looked extremely weak. Immediately the homeless dog filled me of sympathy. So I decided to take him home. I gave him some food and a bath. After the bath he looked energy and refreshed. What a lovely dog!
When my parents got home, I asked that I could keep the dog. To my surprised and joy, they agreed. Up to now, he has become member of our family and everyone had enjoyed his company. Looked at the cute and happy dog today, I realize that I was right to help him. I offered him a shelter and he brought ourselves great happiness and laughter.
