The Training Mode expands to 3 dogs and the Containment Mode expands to any number of dogs.

With 3 modes of operation, you decide which signals the Collar Receiver responds to.In Containment Mode, the Collar Receiver only picks up radio signal that has been sent through the Boundary Wire from the Fence Transmitter. While wearing the Collar Receiver, when your dog approaches the Boundary Wire and steps into the Warning Zone, a warning beep will be delivered. If your dog continues towards the Boundary Wire and into the Stimulation Zone, a safe, static stimulation will be delivered through the Contact Points to get his attention until he returns to the Boundary Area.
