Autumn has one for when my stepdad gets grumpy about her siren bark. It doesn't hurt bad, I've been shocked by it, but I don't like the things that stick into the neck. It has to be uncomfortable for those things to be poking your neck, it has to be tight to work properly. I've been working with her and my stepdad though and she's getting better. He gets into this angry jealous rage because she only barks at men and he's the only man in the house.
