More and more families like to keep dogs as pets.But not all dog owners think of others while they are walking their dogs.So many towns and cities around the world f 1 a mess of leftbehind feces(糞便)from dogs.

In February of this year,a town in France started a new p 2 to teach dog owners a lesson.The g 3 sent about 20 volunteers to search the streets carefully,looking for humans who wouldn^clean up after their dogs.The volunteers who seemed to have no c 4 aim would then move nearer to the pet owner,then start a conversation in order to get the dog’s name.“W 5 the name of the dog and its type,we can e 6 discover the owner from the registered(登記)database(信息庫)held in the town hall."an officer e 7.The volunteers would then pick up the dog feces and the package would be p 8 to the pet owner’s house.In the past few m 9,the town has seen a 70%decrease(減少)in the amount of dog feces left on public streets.

Maybe many cities in our country can follow its e 10.In this way there will be fewer complaints about dog owners.
