I was trying to use the clicker, we've tried turning our backs on them, but they run around to the front of the person (LOL!). We make them sit for treats whether it is someone coming over or us returning from somewhere (together or not).
The noise maker only works on Missy. Chelsea is not afraid of it. DH also made one for by the side gate....just pebbles in a soda can.
Love All Life, Thank You For Posting! :)
