But my dog has figured out that the collar produces the shock - she straightens up and flies right with the collar on even when the batteries are run down. She also recognizes the collar box when I take it off the shelf. She doesn't exhibit any symptoms of fear (this dog is afraid of absolutely nothing except large cement trucks with the mixer turning) but you can see the "oh-oh, I better behave myself."
Sometimes I turn it off and let her wander around the house and sleep with the collar on, just to try to throw her off balance.
For my dog, the collar meant work, like pulling out my shotgun or hunting vest, or the ball I used to train obedience. He got excited when the collar went on.
Can I confess to a cheat I did without ruining my reputation? ;~D
Logan would misbehave at obedience shows precisely because he didn't have the collar on. (He would get up and mount the dog next to him in the sits and downs. Ack!) I had a brass plate with his name on it made, that fit the holes for the leather collar the remote trainer was on. I just left the attachment rivets on the name plate a little long.
