KOCASO Electric Fence for 2 Dogs, Underground Dog Fence System

The KOCASO Electric Fence System is an underground dog containment solution designed to train and keep dogs within a specified safe area. The system includes a wall-mounted transmitter and buried boundary wires that create an adjustable containment zone of up to 1.2 acres (53,189 square feet). The system features a collar receiver that automatically delivers a warning beep followed by a progressive static correction when a dog approaches the boundary, with the intensity increasing as the dog gets closer to the wire. It supports up to three dogs simultaneously, with collar receivers adjustable for neck sizes from 7.5 inches to 17.92 inches and suitable for dogs weighing 4 pounds and above. The transmitter includes a wire break alarm to alert the user of any breaks in the boundary wire and a low-battery indicator for the collar. The system is intended for do-it-yourself installation and is designed for use under owner supervision, with a recommendation not to leave the collar on a pet for more than 12 hours per day.
