Review on Enhance Your In-Ground Fence with PetSafe Fence Wire and Flag Kit, Complete with 50 Flags and 500 ft of Wire by Amber Westbrooks

Was really nervous (no pun intended) about buying it just because it was so much cheaper compared to the other electric fences listed here. But it does the job. My 100 lb German Shepherd is very territorial and stubborn and will run outside if he sees another dog running. So instead of waiting for an incident, I needed a quick fix to leave them in the yard while I work in the yard or take them out. It was so easy to set up and the instructions were very clear on how everything works. From the initial shock of running out into the street, she realized she couldn't go any further than the white flags. It's been a few months since I installed it and she knows how far she can go. Now he doesn't even bother barking at other dogs so that was an added bonus.
