When you take a walk in any of the cities in the west, you often see a lot of people
walking dogs. It is still true that the 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 the 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 protect themselves against attacks of animas.
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 young couples, a dog is their child when they have no
children. For old couples, a dog is also their child when their real children have grown up.
So the main reason why people keep dogs has changed from protection to friendship.
