Some people regard keeping pets, like dogs, as useless thing. But I hold the opposite view or I have a dog myself. I keep a pet for three reasons. First, pets taught responsibility. After I get a dog, I think it’s my job to feeding him and take him for walks after school. The second reason is that he can makes a good companion for me when everyone else are busy. Now, I seldom drive Dad crazily always asking him to play with me. The third reason why I keep a pet dog is for safe. He can warn my family from danger and keep our house safe. I love my dog very well and I’ll always take good care of him.
