Just trying to give you an idea about how small Sparty is or how big Clancy is....the gray box on the side of Clancy's neck is his electric collar....we have an electric fence and all the dogs have a collar....it works amazingly well....it is also called an invisible fence since the cable is underground. Works on a signal...the dogs hear a beep if they get too close to the fence and then, if they ignore the beep and keep going...they get a small electric "zap"...they are all excellent about not testing their boundaries. The "zap" is not hurtful...it is like a static electricity charge.
