The Pet Barrier Dog Fence System is designed to protect your dog from an over-correction in the unlikely event that your dog gets caught in the signal field. If your dog does not exit the signal field, the collar will automatically stop correcting after 15 seconds to protect your dog from over-correction. The dog will also receive a `warning` correction every 15 seconds which will continue until he leaves the field.
