Bests & Worsts Reviews from Amazon

I should have gotten this a long time ago. It works wonders for my barking dog. I used this along with a verbal sound and he was broken of his bad habit in 3 days. Now when he hears the verbal command he stops. Don't get me wrong. Dogs are allowed to bark. But when it's the same routine and he should know better by now it's not acceptable. No more yelling at him to stop yelling!
