I have a 1year old Cavapoo that loves to bark. We are campers and I knew that his habits had to change. Most of the other no-bark devices have a beep and that is the same tone as his invisible fence so he would not leave the camper. Then I found the Bark Silencer 2.0. Saying "No Bark" and using the Silencer just a few times, all I have to say is No Bark and he just looks at me. It is AMAZING! Only draw back is that we also have another Cavapoo that is 4 (who doesn't bark) and he hears the noise and hides under the bed. lol.
HIGHLY recommend.

Bark Repeller XT

The bark silencer arrived quickly. I used the silencer over a 3 day period with my 6month old rescue terrier mix, within 3 days the attention barking was decreased by about 80%. Myself, all the neighbors and my little pup are now living harmoniously.

We have one very aggressive barker when it comes to anyone encroaching on his territory, which includes the sidewalk across the street. We didn't want to try a bark collar and nothing else we tried prevented him from barking and growling like the beast he thinks he is. We were clued into another noiseless bark silencer but upon searching for said silencer, I came across the Bark Silencer, the price was right so I thought I'd give it a shot.
AMAZING! I knew the 1st setting wasn't going to do anything for this little wannabe big dog, so I tried the 2nd setting right away. I touched the button just once for a millisecond and he immediately stopped and came to stand by me. I was in love!
After more consistent training with it, he now stops barking when we say so and not at the push of a button. This is exactly what we needed. Thank you for making something that finally worked for us!

My dog barked at any little noise and it was not peaceful at home or on a walk. I used the bark silencer a few times. When she would bark, I would use the bark silencer and say, “no bark”. Then I would say, “good quiet” and give her a treat. She didn’t like the silencer. She stopped barking like crazy and if she barks now unnecessarily, I don’t use the silencer. I just say no bark, she stops and comes to me and I say “good quiet” and that is it. We have a peaceful home and it’s nice to have peaceful walks.

I bought it to stop my neighbors' dogs who nonstop bark when outside. It works.
I've now used it occasionally on my dog when needed

Barker Silencer works as hoped! Barking neighbor dog no longer an issue when we are in our backyard. I carry control outside & bring back when going inside. Much more peaceful.

This is the only thing that has worked in 3 years with my malinois.

Great Only use one time.Just need to pick it up and he stops barking.
Now I need something to keep him from darting out front door when someone knocks.

Bark Silencer 2.0

I have to furbabies that would bark at absolutely anything! Things I couldn't see or hear. They about drove me crazy. After just a day or 2 saying "stop" and giving them treats when they would stop barking with the bark silencer, they now will stop when I just say the word "stop" 95% of the time. On occasion I have to use the silencer and say stop. But thats rare now. I absolutely would give 10 stars if I was able.

I used the silencer through a fence and the barking stopped. There was no crying or any other sound from the dog.

I USED IT 3X FOR TRAINING WITH BARKING, NOW IT IS HARDLY USED EXCEPT FOR WALKS AROUND OTHER DOGS. GREAT PRODUCT

It doesn't work on all dogs, but I'd say it's effective on 50% of the dogs we come across every day when we walk our dog. We've found those little yappy dogs don't seem to respond, and it doesn't bother dogs (with hearing problems?) that appear to be older. We still like the product -- 50% effective is much better than nothing!! One dog (was being walked without a leash) was running over to us and our dog when we trained the Bark Silencer 2.0 on it and pressed the button. The dog stopped dead in its tracks, turned on a dime and ran back to his owner! Well worth the money, no matter what!

Bought as gift for father-in-law who does not like how their dog goes crazy every time a guest comes over. This product works like a charm and something he can do without even getting off the couch. He loves it!
