Innotek Pet Fence Underground Wire
This pet fence will let pet know he is approaching the end by sending them a beep. If he gets to close it will be followed by vibration and static electricity by collar. This tool will keep him in the "Zone" placed by the wire wherever you would like!! One of the best things about it is that as long as every Pet has its own receiver collar, you can have as many pets in the area as you like!! Up to 5 acres!!!goat, cat ,dog, sheep!!
