The Dogtra 2300NCP-RX collar can be used to add a dog to the expandable 2300NCP.  It can also be used as a replacement collar on the traditional 2300NCP or 2302NCP Advance systems.   

Note: As of June 2016 Dogtra 2300NCP Advance is now expandable to a 2 dog system. If you already have a 2300NCP check your handheld transmitter.  If there is no toggle switch it is not expandable.
