Harmless Ultrasonic Dog Bark Control Devices Waterproof Outdoor Anti Dog Bark Controller Bark Stop Repeller Silence Dog Training Repellent, Easy Hanging with 3 Mounting Modes

This looked too good to be true. We want our dogs to alert us of of visitors to our home, but they don't need to bark at the neighbors. We had immediate success with this device and highly recommend it.

Dogs became immune to the sound!!! No longer works, at all. I followed the directions to a T turned it off for 12 or more hours a day, to avoid the dogs from becoming immune, but it still happened! I was very impressed at first, but not very disappointed!!

Did not stop neighbors dog barking

I have positive and Negative about it...Positive: It has a tiny pitch sound that even you can hear but its not annoying... At first our dog didn't understood what it was, But now when he starts barking uncontrollably I just point to it and he knows he has to stop or I'll turn it on.. We have a pomeranian and we used on level 1, but only turn it on for a 3 minutes or so. We only turn it on for a moment, because it does start beeping if you're talking to close to it. After we turn it on, he stops barking and behave's better. We usually turn it on when we have visitors.Negative: NOT sure if it would work for someone who wants to have it ON all day cause it will beep for every sound around the house... I think it works if you want to train your dog.

This product does nothing to deter barking. Dog still barks all night no matter which setting I use. Don't waste your money!!

Did not work. My neighbor’s dog never noticed or responded to the sound.
