Whistle dog activity tracker
Most of the Bluetooth peripherals for smartphones today are designed to track fitness and health activities -- for human, that is. Whistle Labs is taking that "quantified self" concept to the dogs, with its $129 Whistle collar attachment for your pooch. Use it to track your dog's activity levels and timeline to others of the same breed and age. You can sync the data via Bluetooth such as while you're walking your dog, as well as via the Internet over Wi-Fi such as to keep tabs on your pet's activities while you're out of town.
