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 an animal.Why do they keep dogs, then?
