Anti Bark Device for Dogs Outdoor: Portable Dog Bark Deterrent Devices to Stop Unwanted Behavior- Barks No More Dog Training Device Ultrasonic Control Silencer Indoor - Stop Neighbors Dog from Barking

Great little device, recharges quickly via USB C and worked the first time I tried it and within a couple of days has already significantly modified the neighbors dog’s behavior. My next door neighbor (who happens to be hearing impaired) has a young dog who unfortunately hasn’t had any training and would bark literally incessantly for hours. The poor thing is very sweet but I think he misses his owner while he’s at work. I tried talking to the dog and befriending him with treats and head scratching and attention but as soon as I turned my back he would begin barking, and barking, and barking. I don’t know where the dog gets the energy to keep barking but he apparently has it. Anyway, as I said the effect is immediate, the dog doesn’t apparently really doesn’t like the silent to human ears sound that the device produces and immediately stops barking and slinks away to sit quietly. Problem solved, and I’m hopeful it will continue to be effective if necessary.

Worked quite well. Stopped the neighbors dogs from barking. What a relief

It doesn't necessarily work on my dog. The vibrations don't even phase them. It's easy to use just not that effective.

I feel like it didn’t work as intended. Dogs were more interested in flashing light rather than noise it self. Did not stop barking.

Works great to keep your dogs from barking as much

Seems well made. Doesn't do anything for either of my dogs. It does beep, and even that is ignored. Know others who swear by then, but was ineffective in our home

We have a Sheltie and she is very vocal. We were at the end of our rope with her barking. Within one day that all changed. We used the red button 3 times and that transformed our dog. We only have to press the beeper now to stop her barking. It's a miracle. Highly recommend this for barkers!

I might have received a defective one because it just did absolutely nothing. I played with all the settings and the dogs just don’t respond. Sending back.
