Dog bark control training handheld device.

This worked great for my small house dog when she got a bad barking habit, we no longer needed it as she got elderly. It's like new condition, the picture with the green light circled shows it lit up when you press it to give a high sound frequency that we don't hear but definitely gets the dogs attention. I used a one word command of quiet with a hand signal and it worked good for me and I was able to get where I could just say quiet and my hand signal without using or once in a blue moon using the device. My dog was more middle age when I used this. Sells for new $25-50.
