Dog bark Control Collar with Sound and vibrate Functions, no bark Collar, New 2018 Effective Anti bark Collar for Small Dogs to Medium Dogs, Durable e-Collar for Barking Control.

I was hesitant to buy this at first since there were not many reviews, but I am so glad I did! I just have to turn the noise on for my dog to understand not to bark. The instructions had some incorrect grammar, but I was still able to understand them fine. I am very happy I purchased this product and would buy it again!Note: My dog is 30 pounds, so I bought him the medium sized collar. I wish I would have purchased the small size! It's easy to make the collar small enough to work for him, but I just had to attach a loop for the extra fabric since I had to make it so small.

this worked. the dog understood not to bark when it was on and it only took a few wears for him to figure out when not to bark.

It didn't really help my dog, he only stopped briefly due to the sound but barked continuously. The battery died in less the a week because he barked so much

Works good and does not hurt my dog.

Really a waste of money and time no real directions on how to use just to run it on and off and up sensitivity levels doesn’t even vibrate and on top of that all it does is make a sound that’s it.
