To hear barking in your dream, signifies that you have a tendency of barking orders at people instead of asking or talking kindly. You are annoying others or vice versa.

If you see a happily barking dog in your dream, it denotes pleasures and much social activity.

If the dog is barking ferociously, it represents your habit of unnecessary complaining about people and the situations around you. It could also indicate unfriendly friends around you.
