For dogs, there are many training tools that you can use tohelp them exhibit the proper behavior. One of those training tools is a nobarking collar. The no barking collar is supposed to train the dog not to bark.It is a good tool for a dog that barks incessantly. Of course, it may beconsidered cruel depending on your thought process for dog training tools thatexhibit the control. So let's look at the no bark collar in depth. 

First, you need to understand that barking in an instinctualbehavior for any breed of dog.  They willbark in response to potential threats, happiness, or just to hear themselvestalk.  Since it is an instinctualbehavior, it is most difficult to train the dog not to bark. There are certaindog breeds that will continue to bark for no reason at all. These dogs usuallywear on their owners and their neighbors. If you are going to attempt to trainyour dog from barking you will need patience, persistence, and a gentlehand.  Most often the effective trainingdoes include the no bark collars.

The no bark collars work with an electrical pulse. Theelectrical pulse is set low so that it will react when the dog barks. A dogwearing one of these collars is going to get a little shock. It is usually akin to a shock from the carpet when you touch metal. It is unpleasant, but notharmful to the dog. You can increase the electrical shock or decrease it basedon the training you are going to be doing. The more they wear the collar theless the dog should bark. You are programming your dog to believe that whenthey bark they will get shocked, and if unpleasant enough it will reprogramthat instinctual behavior.

Of course the downside is the chance that they will not barkwhen it is necessary. Since you are training them not to bark at all, for anyreason, the chances of them barking when there is an intruder or other threatwill leave them silent. This means that you are in effect taking away one oftheir weapons against nature. This can have some irritating or bad effects if thedog can't bark to show there is danger. On the positive side, this isn?tusually an issue for people who have security systems in their homes, as thesecurity alarm replaces the need for a dog's bark.

When training, you do not want to over use the no barkcollars. You should use it at a technique to keep the dog from barking ateveryday things, but also incorporate other methods of training to showsituations when it is okay for the dog to bark. For instance, you can use avoice command such as ?speak? to teach the dog that he may bark when told to. Again,the choice to use the no bark collar lies in how you view the training method.Some prefer it, as it offers a hands-free approach to training, yet othersprefer voice commands and hand signals.
