Needed an effective bark deterrent. My dog is extremely protective and defends her space and people without prejudice! Her barking can get excessive at times, and this worked immediately! No more yelling for her to stop, and my neighbor probably appreciates it more than I do. After talking to my vet, I was reassured it's safe for my dog. Great product!

So far this is working great,I have found after a few days use I don’t actually have to use it,just carrying it is enough to stop her barking,peace and quiet for everyone.

Great training tool!I have a 1-year-old Golden Retriever who gets extremely excited when she sees people. She jumps, barks, and generally goes wild, making it hard to calm her down. Despite my training efforts, she seems to forget everything when guests arrive. Someone in a Facebook group I'm part of had similar issues with her Golden Retriever and recommended this device as a great training tool. I decided to give it a try, and within the first day, I noticed a difference. A quick press of the "silent" button (silent for us but not for dogs) is all it takes to calm her down. After a few days, just grabbing the device is enough to stop her chaotic behavior. I can't emphasize enough how much this has helped in such a short time. I highly recommend it as a great tool to complement training!

A Game-Changer for Training- I'm Ordering a Second, I've struggled with training my pack of nine rescued mutts for over two years, trying everything from whistles to shock collars. Yet, whenever a stranger drove up to our house, chaos ensued with barking, jumping, and general mayhem. We stopped having visitors because of it until I used this fantastic little device, twice. The first time they started their barking frenzy, I used the tone for a fraction of a second. Amazingly, they all immediately stopped and returned to the house. It took one more instance, about three days later, with another half-second tone, and calmness returned. They each stopped, came back to me, and sat around me, something I'd never even asked them to do before.

While I'm sure this tone can be misused, I can't see why anyone would. Perhaps my pack is unique, but I doubt it. In my opinion, this is the best training device ever invented. No one paid me to write this, and I paid full price for the device. I'm not getting anything in return.

it works brilliantly. Excellent product, I have two Border Collies, a male and a female. My male Border Collie used to be very disobedient, constantly barking and needing to be restrained whenever we went to the park. But ever since we started using the NPS Dog Bark Deterrent Devices with 3X Sonic emitters, he has completely changed. This device works wonderfully; he stops barking instantly and follows every command we give him. The transformation is remarkable! He now behaves just like his sister, making it a joy to take him anywhere. The best part is that this device is very safe for my dog. I consulted with my vet, who assured me it causes no physical harm and absolutely no pain. I highly recommend this product.
