This message is from my long time professional GSD trainer, exhibitor & friend in Minneapolis. Kathy www.JoKaySedona.com <http://www.jokaysedona.com/> >It doesn't hurt their ears. It like a huge voice yelling "HEY"!!! You don't blow it long just as short a blast as you can while yelling "NO"! I've only heard of it working and no negative effects. I know one woman that used it too much. The Sheltie quit paying attention to it. Does that sound like a dog getting injured? I'll go with experience and demonstrated performance. As we all know, best way to break up a fight of course is to prevent it from happening in the first place. ======================== ============================================================================ POST is Copyrighted 2014.
