Review on Amazingbuy Electronic Dog Training Tool - Ultrasonic Dog Repeller/Deterrent for Barking Control - Stop Barking Sonic Dog Trainer Device (Black) by Leah Gomez

Wow! This device is available. When used correctly, I couldn't believe the instant results. My only dog loves to jump and bark. Another smaller dog was abused early on and is barking and biting. Not much more! We used this tool four times and each time it got better and faster. Four times within a month. Dogs now clearly understand that no! Given that dogs are family-loving members of the family, they just don't like strangers. My dog panicked the first time I ordered it. One ran out to pee in a nervous reaction. Once calmed down every time after the fear is there but they understand. I still want dogs to be able to act when danger arises. Wow!
