Review on 🐕 XIAXUE Anti-Bark Control Device: Ultrasonic Dog Bark Deterrent with 50 FT Range - Stop Barking Now! by Mariana Vasquez

I have two talkative GSDs that annoy my neighbor. Thought it might be worth a try. It arrived yesterday and I plugged it in from the front and noticed results straight away. My dogs don't like what they hear when I say "woof-woof, in test mode" and they also stop barking with puzzled expressions on their faces when I set the speed to 50 minutes. But then the neighbor's dog, about 50 meters away, started barking and the light was still flashing, indicating he was making that noise. I turned it 20 feet and the flashing stopped even though the neighbor's dog was still barking 150 feet away. If it continues to work as well as I've seen it, they will definitely be a Christmas present. *_*
