it also helps you and the dog if use the dog's name mainly for rewards or to get it's attention. make sure you let it know when its done a nice job. but, if it's chewing on shoes or household shit, instead of growling its name, replace it with short, sharp commands. 'no', 'hey', 'get back', 'bad'. because if you constantly shout its name, over time it'll just think of it as another saying and ignore it.
