When I take a walk around Washington Square Park, I often see many people walking with their dogs. It is still true that the dog is the most useful and faithful animal in the world, but the reason why people keep dogs have changed. They used to keep dogs in order to keep safe, but now they keep them as friends, because the city can be a lonely place. For a child, a dog is a playmate (玩伴) when he has no little friends to play with. For young couples, a dog is their friend when they feel lonely at home. For old couples, a dog is their child when their real children have grown up. Now you can see the reason why people keep dogs.
