Keep the ones you love close to you—including the furry ones! With the Extreme Dog Fence Standard Grade Electronic Dog Fence System， you can feel better about your pets staying safe when you can’t watch them yourself. Creates an invisible boundary where you need one with the dog fence wire， which covers up to ⅓ acre with the kit and up to 6 acres with the purchase of additional wire. When you place the receiver collar on your dog， you’ll be good to go due to seven customizable correction levels based on your needs. It’s even waterproof! When your dog wears the collar， it activates as he approaches the wire. After several days of training， your dog learns to respect the boundaries that you have established. This convenient kit includes a digital transmitter with power supply， a waterproof collar receiver， heavy-duty 20-gauge boundary wire with a thick 30-mm polyethylene jacket， training flags， and splice kits.
