Review on 2021 Latest GPS Wireless Dog Fence System - Waterproof & Rechargeable Training Collar for Dogs & Cats Over 5 lb - Ideal for Outside Camping Yard - Electric Pet Fence Containment System by Erica Johnson

Super beautiful electric fence. Easy to set up and use. Just set the control distance which is the radius of the fence circle you need. Put the collar in setup mode and position yourself in the middle of the desired fence line. This allows you to adjust and fix the control distance. As soon as your dog approaches the edge, he will warn you with a sound signal and shock you if necessary. You can also set the intensity in the settings. Includes two adjustable collars and shock device. Easy to use, great price, I recommend!
