I have two dogs and got one of these bark collars to test it. It works great! It has stopped my dogs barking and I feel better about my dogs not bugging my neighbors when I'm at work. I came back to order another and it's not available. I'm hoping they have one soon.

This works great on my Doberman.I can put him outside on his runnerWhile cleaning and not have to listenTo him bark the whole time.

Overall, the product is excellent. Our only problem is the quality of the collar itself. It unravels fairly easily.

I have used this for three days for my 12 pound chihuahua and it has worked wonders!!! He doesn’t bark at all with this on the lowest setting possible of vibration. I don’t even use the shock setting and it has stopped the barking. Highly recommend

This product does keep my girl from barking when I'm at work. When she shakes here head sometimes it goes off, good thing I dont use the shock option.

I am well impressed with this collar. The product exactly corresponds to the description. Works great. On the average dog power more than. The collar is long enough, which allows you to perfectly adjust the neck of the dog.
