Our Yorkies still bark a little, but we have the control to either allow it or turn on the Bark Off and tell them "NO BARK" and silence is ours to have. We don't leave it on all the time, since we do like to know that someone is outside our house, or let them bark at their friendly cat going by. But if the Yorkies don't stop barking after first announcing a strange noise, a cat or someone outside, we flip on the Bark Off and a little "NO BARK" and they settle down instantly. Now it might be all psychological, we might just want it to work so bad we think it's working. Anyway, something makes the dogs stop barking...maybe it's the shape of the device or maybe they can read what it says on it, "Bark Off" and they just stop barking because of that.
So now Shiloh has made peace with his new toy, well, our new toy. He will even lay down beside the Bark Off on his favorite Redskin blanket. The Yorkies have been trained to quiet down just by seeing the Bark Off come out. And if they don't stop barking within our set time limits, a flip of the switch, a little "NO BARK" and silence is ours again. We know it's a combination of the voice commands and them seeing the device, but hey if it works...we got something for our money. We just don't buy batteries for it anymore...just the sight of the device and our "NO BARK" works...but we would have had this outcome if we hadn't tried the Bark Off device.
So if you have a excessive barker you might want to give Bark Off a try. You might get better results then we did, hey it might even work like it's suppose to. Check them out at http://www.barkoff.info/ and see for yourself what Bark Off is all about. Good Luck!!
