MASBRILL Ultrasonic Anti Barking Device, Handheld Dog Bark Deterrent Device Stops Bad Behavior, Alternative to painful dog shock collar

I love it. I've only had it a couple of weeks. I saw the results in the first few days. Now if he barks I just pick up the device and he sees me with it he will stop without me having to actually turn it on and use it. I know story sounds made up but it really is TRUE!! Hope you have the luck I had,

Our next door neighbors have three pitbulls and one will bark all day long from just the wind blowing. I bought this though I was skeptical. THIS REALLY WORKS! As soon as we pushed the sonic button the dog quit barking, put her head down, and ran to the owners back door. We have already bought two more of these to keep around the house.

I like that it quiets my dogs. i think one dog could easily be trained with it. with multiple dogs i have to use it whenever my dogs bark and i want them to stop.

Works very well. Use the beep button first as a warning and if they don't stop barking then the high pitch button. They have learned to stop when hearing the beep button before I even have to use the high pitch one. Excellent.

This is an excellent training device but dont use it casually - cus while i was trying to train my naughty dog with it - my well behaved dog who was deep in sleep just woke up shocked and could not sleep for an hour - so be careful - and when you take your dogs for a walk and as soon as they walk ahead or pull - Say NO and just press the first button so they can associate the unbearable ultrasonic sound with the word NO. it can be easily recharged using the C charger

This device is single handedly the best thing I have purchased all year. We have dogs all over the neighborhood. Most of them are used to the neighbors and only bark when threatened. But we have an irritating puddle type next door that even after 4 years, still barks constantly the whole time we are outside. Two days of using this gadget has brought sweet quiet. We can enjoy our backyard. My only regret is that I didn't have it 4 years ago.

Makes sound and is easy to use but none of the three dogs I've tried it on even flinch. These dogs are very aggressive and crazy but they don't back down at all. Unsure if the device works as intended. I've used all the modes and been a foot or two away while using it but the dogs never stopped barking nor reacted like the sound was annoying enough for them to stop.

I know this device doesn't work on all dogs but this device seemed to be ineffective for all dogs.

This didn't work to deter my dog's behavior.

It doesnt work for reactive dogs.
