If you find yourself wondering when you might get a decent night's sleep, enjoy a quiet afternoon, or be smiled at by your neighbor again, it's probably time to think about a bark control collar. The fact is, dogs bark. They do it when they're excited or when they sense danger. Some do it when they're bored - or worse, for no reason at all. In these cases, you want to teach your friend that barking is only permitted under certain circumstances.
