We have a young Cocker Spaniel (Bailey) to us.who is an absolutely terrific friend to my wife and I. The only issue we have had with him is his desire to have the last word with any dog within hearing. His barking was getting annoying especially in the house. We purchased the dog debarking device from the Dog Line. It makes a noise only dogs hear when he barks, the results are instant. It fixed the problem within days. We only use it now on rare occasions when he forgets. Mostly we just show him the machine without batteries and he remembers that he doesn't like it. I also purchased one for my Brother in Law who has two boisterous and very vocal dogs. He also had similar results. The website was easy to navigate and the purchase was delivered very quickly. I would recommend the Dog Line to anyone looking to get aids to assist their best friend.
