Virtual Leash allows you to set up a virtual perimeter between you and your pet and is intended for outdoor use. You must be within 300 feet of your pet to enable this feature. On the home screen of the Pawscout App, select your pet. In the map view, select the "+" sign and "Virtual Leash" when the paw menu appears.
Make sure to unselect "Virtual Leash" when you no longer need it so that you do not receive false alerts.
