Tagg—The Pet Tracker is a purpose-built device that uses advanced GPS and wireless technology to track a pet’s location and activity. The lightweight, water-resistant Tagg tracker attaches to a pet’s existing collar. With Location Tracking, if a pet leaves the designated “Tagg zone” (geofence), the owner is quickly notified by text and email so they can find their pet on a map that shows the pet’s last known location with an estimated street address. With Activity Tracking, the owner can track a pet’s daily activity levels to help ensure the pet is getting the proper amount of vet-recommended exercise.
