Dog owners now have a little help understanding their furry friends . A new device called Bow-Lingual "translates" dog barks into English , Korea or Japanese. Bow-Lingual's Japanese inventors spent much time and money analyzing dog barks . They found that dog noises can be broken down into six different emotions : happiness , sadness , frustration , anger , assertion and desire . Part of the Bow-Lingual device hangs on the dog's collar . The other part is a handle-held unit for the owner . When the dogs barks , the unit displays translated phrases . Some people have scoffed at Bow-Lingual. "Who would pay US$ 120 to read a dog's mind?" they ask . But those who have purchased Bow-Lingual praise the device . Pet owner Keiko Egawa , of Japan , says it helps her empathize with her dog , Harry . "Before we go to the park , he always says he wants to play," says Egawa , "and after a walk , he always says he is hungry." Bow -Lingual is not yet available in Chinese . So you'd better keep studying Studio Classroom , or soon your dog may know more English than you do ! This passage is mainly talking about  _  .
