Review on Advanced Ultrasonic Bark Control Device | Hand-held Anti Barking Device for Dogs | Variable Frequency Dog Barking Deterrent & Behavior Training | Effective Dog Repellent & Barking Control by Pamela Pickett

This simple device works wonders for my dog!. He was generally well-behaved and, until recently, did not speak very loudly most of the time. I don't care if he ever barks unless someone is actually in front of my house. This thing will fix its unwanted barking in an instant. I doubted it would even work, but I'm impressed! Mind you, I have a friend who has a dog and doesn't seem to care much about it. His ears twitch a little, but he keeps barking. Maybe some dogs just don't care? I'm glad it works for me and I don't have to put a collar on it like I do with other products. My only comment: I wish there was a real on/off button so little kids can't accidentally press the button and confuse my dog. It's okay, but maybe it can be added in the next version.
