Meet the SpotOn GPS Fence: a smart dog fence and collar that helps you track your dog’s location within 10ft with 6-second updates. You can also customize up to 20 fences from 1/2 to over 1000 acres. These fences can be across water and other challenging terrain.
With an optional cell plan, you will be able to see your dog’s location and get notified when they leave. You can use this with AT&T or Verizon. The battery lasts 14 hours in tracking mode.
