I have two labs and they bark to come inside after being let out. I put it on the back porch, and they stopped barking. Worked great pretty much instantly. It says to change the frequency every once in a while which can be done by turning the knob. Charges via USBC. It fits the bill for what I needed.

We recently sold our home, and we have temporarily moved in with my parents, they have 2 chihuahuas, we have 4 large mix breed dogs. None of those dogs are used to being together, and my mom’s chihuahuas SCREAM anytime they hear a noise. Which then caused a chain reaction and all 4 of my dogs would start howling at the top of their lungs, when the chihuahuas would start barking. So imagine 2 chihuahuas yapping non stop for minutes at a time, and 4 large dogs howling like wolves. I realized IMMEDIATELY this living situation was not going to work out if we couldn’t find a solution. That’s when I found these. I ordered 2, one for the garage where my dogs kennels currently are, and one for the main house, where the chihuahuas are. These things are AMAZING! I won’t say the dogs don’t bark here and there, but I can open my bedroom door and you may hear a quick bark or two but then they stop. It used to be minute long fits anytime I made a sound, not kidding the day we arrived I sneezed and they barked at me for like 2 mins straight. These bark boxes have changed my parents lives, and honestly I feel like the chihuahuas are more calm now that they’re not screaming their heads off anytime anything makes a sound. Totally worth the money. I love that they’re rechargeable. We’ve had them for about a week, and they’ve been on non stop, and we’re still going on the first charge. If you’re considering trying it, just do. My big dogs are more of alert barkers, but my gosh these chihuahuas are LOUD and constant, and this absolutely fixed the issue. Now they’re even listening to me better for additional training. Seriously just try these if you have a barker.

I’ve got two doggos and I work from home. Most days, my dogs will lose their ever loving minds SEVERAL times a day. I’ve tried numerous collars over the years and my dog outsmarts them. She KNOWS how to out-bark the devices and NONE of them have ever worked. My oldest dog is 8 and I don’t think my home has been quiet for a full day since she first came home.  But today…….today has been GLORIOUS. This device is EVERYTHING. Neither dog has barked since they first tested this new device and both dogs are actually calmer today since they aren’t running around barking at everything that moves.  It comes with two boxes, smaller than a cell phone. So we put one up on a shelf in the living room and one on the fence in the backyard. Now I’m sending this product to everyone I know who has a dog in my neighborhood.  “Shut up and take my money.” Is what you should say if your dog barks and you’re losing your mind.  It doesn’t hurt them but very much deters my dogs. I appreciated the clear instructions that told me which setting to use for my “naught dog” lol.

I charged the units as instructed and after returning home from work 8hrs later the box was already dead. I charged it once again and my dogs could care less. Did nothing

I live in a neighborhood and share a fence line with 2 very aggressive and obnoxious barking dogs. They try to attack myself and my smaller dog while we are just out in our backyard minding our own business. Besides the aggressive nature, they bark at everything and no owner ever corrects the constant obsessive nuisance. In desperation of my sanity, I decided to try this Anti Barking Device in an attempt to at least keep them from barking at us in our backyard. I hung them on our fence line. I can’t tell what they are doing…but WOW! They are doing something because suddenly life is a whole lot quieter. I wish I had these sooner! They are easy to charge and last about a month. I can’t speak to the weatherproof, because I have only had them a few short weeks. But so far, so good. I don’t plan on keeping them outside during our Alaskan winter since it’s really only the summer that we experience the issues with our neighbors dogs. So far, I am completely satisfied with my purchase and would definitely purchase again.

I have 3 dogs and really wanted this device for 2 main areas. By the gate where one will incessantly sit and bark at everyone walking by and between me and my neighbors house where I have one who like to fence fight. My hope was that, good placement would just keep them away from these areas. Day 1 and I have to say I am impressed. They both learned quick and have avoided those areas all day. We will see if it’s a permanent fix.

I have a German Shepherd puppy, around 8 months old. She would bark when noisy neighbors were outside, having parties and get-togethers. After installation of this box, on medium setting, she doesn't bark at nothing. After a week, she barked twice, for 2 seconds. I'm starting to only use it neighbors are outside, almost worked too good

We started seeing immediate results with this Dog Bark Control Device. Our dog responded quickly to the ultrasonic sound, reducing his barking significantly. The fast effectiveness of this device is impressive and provides quick relief from constant barking. It’s perfect for those seeking immediate results. Immediate reduction in barking, very effective!
