No owner enjoys listening to their dog bark for hours on end. I'm pretty sure that the dog is not going to notice the fine. Dogs don't always bark when they are scared, they also bark when they are happy, or playing. So I can't play with my dog anymore because he barks? All this will result in is more cases of animal abuse and more dogs in the pound. I have an idea- lets fine parents who have babies that cry for more than ten minutes.
