Review on Zxbaers Professional Ultrasonic Whistles Adjustable by Paula Oster

Seems like the dog I wanted stopped barking just barking some more! I also have a headache. The dog next door and a very stupid dog, that's what I expected. All around me, dogs hundreds of yards away start barking. But they quickly stop. Neighbor's dog barks for hours until owner comes out in frustration yelling "Stop you Fxxx Stupid Dog" and then kicks him. So the whistle works. A resentful pit bull will annoy the owner enough if they one day kill them or get rid of them. If I see him kill him, the sheriff will be called again. This dog attacked me several times and was tied up most of the time. Only with rent 3 times in a few months. Hoping for better results, but the dog doesn't have time for animal cruelty.
