South Koreans hoping to communicate with man's best friend could be getting help soon from their cell phones. KTF Corp., a South Korean mobile phone operator, said Thursday it will begin offering a service that will enable dog owners to know whether their pets are feeling happy or sad.

　　The users must first connect to Internet with their cell phones, and then register information of their dogs such as the breed and age. The service will then record the dog's bark.

　　The owner will receive text messages telling them how their pet is feeling, such as "I am happy" or "I am frustrated."

　　The service, which will begin on Friday, will also translate basic messages into dog sounds. The service will cost about one dollar.

　　More than half of 48 million South Koreans use cell phones, and many of them use mobile phones with advanced features such as mobile banking, satellite navigation and high-speed Internet.
