The Ultrasonic Bark Control Collar uses an ultrasonic tone to deter nuisance barking. The collar is lightweight, water-resistant, and comfortable. A low battery indicator will alert you to when the 3-volt lithium batteries should be changed.
I was cautiously optimistic when I ordered this. I have a dachschund who loves to bark at everything!! So after trying it for just a few days, her barking has dramatically improved. She only barks a few times and then stops when she hears someone at the door or at the fence. This little thing really works! Try it; you may be surprised how well it works!
