anti bark coolar
Excellent. I resisted a shock collar for 3 years, now I kick myself for not getting it earlier. I thought it was cruel to shock my anxious, leash aggressive, 75 lb excessive barker, but after I tried everything thing else, I gave in. He got shocked a couple of times and has now stopped. In fact, he's almost relaxed now in situations that used to set him off. He still will bark without the collar, but even then, he doesn't get set off so easily.

Works like a charm!
We have used this for the past month on our 45 lb. Wheaton Terrier and it has been a God-send. He learned really quick not to bark when the collar is on. However, he still barks when it's off. Only complaint is that the buckle is pretty flimsy. A bit of advice: Make sure the collar is on tightly!

Limited use
I don't know if my dogs are too smart or too dumb but this product only has limited use for us. It does work in the sense that while they are wearing it they don't bark. As soon as you take it off and a noise comes from behind the fence or someone walks by out front, they are back to barking their heads off. They have only learned not to bark while the collars are actually on. I can't leave this thing on them 24/7. I have tried this shock collar and the citrus spray collars with exactly the same results. One of my dogs is a border collie and the other an australian shepherd. I will have to research other methods of bark control and not leave it to devices.

Peace and Quiet at Last!
After a year of listening to two little yippers who responded only temporarily to other training techniques this collar did the trick in a matter of days. And the results have held up over time. Our lovable little terriers would bark loudly when anybody passed by their fenced-in area. Living in an urban area - with lots of other dogs and kids around - this happened all too often. Nothing we tried worked until we got this collar.

The vibration sensing feature helps ensure that only the bark of the dog wearing the collar triggers the correction. That was a concern of ours since we have two dogs. We first tried it on the one that barks most and loudest for a week and it showed results within hours. Since then we've alternated one week intervals for each dog and we finally have some peace and quiet around here -other than the neighbors' noisy dogs and kids!

It works!
This item worked pretty well. My dog stopped barking very quickly. One must be careful because when I set it too high,my dog yelp. So make sure you use the settings gradually.
