Review on PILONG Ultrasonic Neighbors Professional Adjustable by Gerald Mcrae

I got this because my dog likes to drive me crazy. He's treacherous that way. When he wants attention and I'm busy with something else, he either shuts himself in (like cleaning a cat) or just shuts the air. Yes, he will sit in one place with his snout in the air and start trapping the air. And when I call his name to ask him to stop, he ignores me. Speaking of selective hearing, because when I get up and go to the kitchen and open the fridge, he hears it FROM ANOTHER ROOM. "WHAT? Weren't you in the living room trapping the air?" So I bought these ultrasonic dog whistles to get his attention when he's in the mood to kick. I decided to blow this whistle, I can't hear it but it can to get his attention and get away from it. NO! I hear a whistle, but he doesn't even slow down, he doesn't hear anything. I adjusted them and NOTHING! Whistle = zero, dog = smarter than humans
