This gadget, developed by the Japanese toy company Takara Tomy, will allegedly translate a dog's barks:

The gadget can tell you if your dog is sad, joyful, alert to danger, needy, happy or frustrated.

The £129 gadget can be placed on the dog’s collar and includes a receiver which would translate the dogs’ barks. The translated bark is displayed on the receiver which also plays in audio phrases like ‘I feel sad’ or ‘Leave me alone’ (no phrases about desiring a juicy steak?) the toy will hit the Japanese market on August 27th

Note that the device will only translate a dog's barks into Japanese, so those of you not fluent in that language may wish to get some help when using it.
