Anti-runaway fence for dogs Comfort Fit Nano

Safe and effective for pets weighing over 2.3 kg. A radio signal is transmitted along a buried wire that marks the boundaries you wish to set for your dog. When your dog approaches the boundary, the receiver emits an audible warning. If he continues to enter the boundary zone, the animal receives a harmless but surprising stimulation. Although harmless, this stimulation will persuade him to stay within the limits you've set. Offering 4 levels of stimulation plus an audible warning only option, the system can be adapted to suit your dog's temperament.
