Oh my thank-you all for your responses....but I would never consider a shock collar, never even thought of it...guess I expected you all to read my mind lol...I had been traveling w/my hubby and reading the sky mall catalogue and saw these sound frequency devices and one was on a collar...heres the link
http://www.skymall.com/shopping/dept...-_-PetProducts Ihope this will take you to the correct place...The sound frequency devices sound like the same effect as the pennies or coins in a can would do. I was curious about the one that stays in the room while your gone, you turn it on and when they bark, it emits a sound that only they can hear, its a neg. reinforcement training also...I'll let you know if it works. I have to do something and I can't stay up here in the apt. when I have a customer downstairs to put a leash on them and lead them to another room and remove them from the area ect....as the trainer on TV does..lol...I appreciate the feedback!
