Technology's getting us close to where we'll be able to have a conversation with our dog. This is the very first step.
A Japanese company called Langualess just created a harness for dogs with a sensor that changes color based on how the dog is feeling: Relaxed, excited, happy, interested, or stressed.
And the harness connects to an app on your phone, so you can track your dog's moods over time.
The company says they figured out how to detect a dog's emotions by studying heart rate patterns for dogs in different situations.
The harnesses should go on sale in the U.S. sometime later this year. They're already on sale in Japan for around $37.
