Good Morning, Silicon Valley reports that

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.”
