Review on Ultrasonic Dog Bark Deterrent Rechargeable by Melissa Moore

I was skeptical at first but the first time I used it my dog heard it clearly and stopped barking to see where the noise was coming from. I use the word "quiet" every time I want her to stop barking. When she's gone, I turn on the ultrasound. I find using a keyword instead of an alert tone would be more effective so she knows what a command is asking her and hopefully doesn't need this device in the future. I also use it to stop other unwanted activity like jumping on people - again with the command "down" followed by the device if it doesn't obey. So far, so good! Another advantage is that the device is rechargeable and does not require batteries.
