Tailtalk clues pet owners into their dog's emotions

Ever look at your dog and wonder how they’re feeling? Tailtalk, which is described by DogStar as the “world’s first dog emotion sensor,” is designed to make it easy to tell.

The device itself is a Fitbit-like wearable that’s placed on your dog’s tail to analyse its every movement and reveal your dog’s emotion. Its video explains that the direction a dog wags its tail indicates its mood.

An app is linked to the device, so you can get updates on the fly. It even works if you’re not in the vicinity of your dog. It showcases how your dog is feeling on an easily understood graph, while there’s also a dashboard showing a dog’s “happiness overview”, “emotional graph” and “emotional diary.”
