The Whistle, released last Fall, is a small metal disc about the size of a silver dollar that attaches to your dog's collar. It communicates with a smartphone app so you can track your pup's fitness over time and check on his activity throughout the day (and make sure that the dog walker isn't just watching HBO GO on your couch when he's supposed to be out with your furry friend.) The new version of the device, slated for a release in the summer of 2015, is the WhistleGPS, which adds location tracking to the mix. But the novelty is how it'll do it--by tapping a brand-new, low-power, ultra-narrowband wireless network that will cover American cities starting later this year.
