Most dog owners feel that their dogs are their best friends .Almost everyone likes dogs because they try hard to please their owners. One of my favorite stories is about a dog who wanted his owner to please him.

One of my friends has a German shepherd named Jack. These dogs are often very intelligent. Every Sunday afternoon, my friend takes Jack for a walk in the park. Jack like these long walks very much.

One Sunday afternoon , a young man come to visit my friend. He stayed a long time, and he talked and talked. Soon it was time for my friend to take Jack for his walk, but the visitor did not leave. Jack became very worried about his walk in the park.He walked around the room several times,and then sat down directly in front of the visitor and looked at him.But the visitor paid no attention.He continued talking.Finally,Jack could not stand it any longer.He went out of the room and came back a few minutes later.He sat down again in front of the visitor,but this time he held the man’s hat in his mouth.

German shepherds aren’t the only intelligent dogs.Another intelligent dog is seeing eye dog.This is a special dog which helps blind people walk along the streets and do many other things.We call these dogs seeing eye dogs because they are the eyes of blind people and they help them to see.Seeing eye dogs generally go to special schools for several years to learn to help blind people.Dogs and human beings accompany each other and live in a harmonious life.

So it is still true that a dog is the most useful and faithful animal in the world,but the reasons why people keep a dog have changed.In the old days people used to train dogs to protect themselves against attacks by other beasts.And later they came to realize that a dog was not only useful for protection but willing to obey his master.For example,when people used dogs for hunting,the dogs would not eat what was caught without permission.But now people in the city need not to protect themselves against attacks of animals.Why do they keep dogs ,then?Some people keep dogs to protect themselves from robbery.But the most important reason is for companionship.For a child,a dog is his best friend when he has no friends to play with.For a young couple,a dog is their child when they have no children.For an old couple,a dog is also their child when their real children have grown up.

Here I want to say dogs can be our best friend,accompany each other and give our companionship.
