Here is a smart wearable device that helps you better understand your dog. The Inupathy Dog Mental State Visualizer uses a special algorithm to analyze your dog’s heartbeat and changes colors to show your pet’s emotional states (relaxed, happy, interested, stressed, or excited).
Inupathy syncs to your smartphone, so you can make better sense of the data. It fits dogs from 3kg to 40kg. The battery lasts up to 12 hours.
