Every person that has a dog needs to make sure that the dog is properly trained. A dog should not jump on visitors or guests when they come into your house. But most of all, it shouldn’t bark loudly and endlessly all day long. Excessive barking can cause you problems with your family or your neighbors. Even the owner of the dog might find that it’s impossible to concentrate on a task or enjoy a movie if the dog keeps barking; this situation calls for a citronella bark collar.
