NTT Docomo recently launched a pet dog-monitoring service called PetFit. It is available for a 25,900 yen fee (approximately $255), which includes a deposit fee for the monitoring device and one-year data transmission charge. By attaching a bluetooth-enabled tag to your dog, the service’s mobile app keeps you updated about how you dog is behaving (is he walking or sleeping, for example). If the device’s base station loses the signal from the tag, the service recognizes he that he is out of range and sends you a notification e-mail to encourage you to find him. You can record history of his past behavior, as well as the atmospheric temperature around him, in the cloud, and even consult a veterinarian using the service. via CNET Japan
