Tagg GPS Pet Tracker & Activity Monitor is a purpose-built pet tracking device that uses advanced GPS and wireless technology to track your pet’s location and activity from your computer or mobile device, 24 hours a day. If your pet strays from your Tagg zone, the Tagg system alerts you by email or text message, so you can find him on a map and bring him home. You can also track your pet’s daily and long-term activity levels to stay on top of his health and exercise. This tracker bundle comes with everything you need to get started.
