Communication between dogs and humans could be improved with wearable tech for dogs. Developed in the States, the harness is fitted with sensors that monitor both a dog's posture and its vital signs and can pass the information to an owner. The device also contains vibrating motors so owners can communicate with a dog even if it is out of sight. The harness was fitted with motion detectors to help interpret a dog's body language and it could help with training or refine how working dogs and their handlers cooperate.
