Bark Box Anti Barking Device Dog Barking Silencer Ultrasonic Dog Barking Deterrent Devices 50 Ft, No Bark 4-Frequency Ultrasonic Dog Bark Deterrent（Black）

This product does not work for my pet or does not work at all. I turned it completely up, and I can hear the frequency but it’s like my dog can’t😭

Product is nice looking to have and not be aware by people visiting. however the purpose was to slow/stop a dog from barking/crying when someone arrived. After a few times, dog has disregarded the tone that was supposed to stop him from barking.

Worked well for about a week and a half. Noticed it stopped working earlier this week, tried to change the battery and that wasn't it. I have no idea what happened, its literally been sitting in the same spot on my kitchen counter and hasn't been disturbed 🙄😒

Used to chill out my doggo at night when trying to sleep

We’ve bought 4 of these for our dogs and the neighbors and they just don’t stop them at all from barking. It doesn’t phase them. Very disappointed.

Needed something for calming the noise at night sometimes and thought this would work. It didn’t seem to help at all and my dogs weren’t phased by it. Tried the different settings but nothing.

I was hoping this would work. It does not. I have three dogs all different ages and breeds. It didn’t work for them.

I would not waste my money on this even though it works great because you will have to replace the battery at least once a week.
