I tried this product as a last-ditch effort, because we love this 90% good dog. Our problem was not barking. Our dog has possession aggression. It said this product worked for bad behaviors. Well, with little perseverance, this works like a charm. My trainer said he was a bad dog because of his biting. This is now the dog we wanted! Thank you!
Bottom Line: Yes, I would recommend this to a friend
