I have a non-barking dog now! Yay!
I was skeptical that it would work, but it really does. Immediately! After a few barks with immediate yelps - yelps more out of surprise than anything - my dog has learned pretty quickly not to bark. It lets him get away with a quiet one, which he does when he needs to. My dog is a 10 year old border collie and after moving into a townhouse and neighbours complaining, I had to do something. If I'd have known how good the results are I'd have done it many years ago. It's a quality item too, well made and goes many days without a recharge, has a power indicator I can see when I turn it off. Gets through my long haired border's fur without the larger electrodes. Very happy with the results!
