Remote Training Systems:
Remote training systems consist of two main components: a receiver that comes attached to an all-weather collar and a hand-held remote control transmitter that sends signals to the receiver. It is designed to assist in the training and the behavior modification of your dog. The remote training systems were created to help dog owners deter unwanted behaviors from a distance. It can be used to control any misbehavior that you see your dog exhibiting by using the transmitter to send a clear signal to the receiver worn by your dog. After a few corrections your pet will begin to avoid the misbehavior. Eventually the same effect can be achieved once your pet associates the tone with the correction, by using the negative tone only.
