The bark control collar effectively and humanely stops most barking when it is worn by a dog. It should only be worn whenever you don't want your dog to bark. Your dog’s reaction to the collar in terms of their barking will depend on your usage of the collar and the temperament of your dog. A bark collar helps you communicate to your dog when it is okay to bark and when it is not. Some dogs will be trained quickly and as a result may not need to wear the collar long term. Other dogs associate not barking with the collar and will only control their barking when they have the collar on.
