If you ever wonder what your dog is up to when you leave the house, the Fi Health-Tracking GPS Dog Collar is for you. With GPS capabilities and a step counter, this device functions as both a fitness monitor and a safety device. The complementary app also allows users to create GPS safe zones for their dog. This way, you’ll get a notification on your phone if your dog’s escaped or gone somewhere he’s not supposed to. You can also use the app to keep an eye on any dog walkers you hire. The collar itself comes in two colors, yellow and black, and a variety of sizes to fit any pooch, big or small. With a stylish and unintrusive design, this device is a wonderful bit of gear for any dog lover.
