Mood Journal- a dog

In the past few days, I almost look like a lunatic person because I cannot have a sweet sleep. My downstairs neighbor raise the dog at the front their house. The dog is a very fierce animal who he gives a continuous several fierce barks in early morning or in the midnight every day. I do not know why is the dog barking at? I cannot find him about why he likes continuous fierce barking at? I always awaken by his noise every morning since two week ago. I feel completely exhausted to face my work every day. I make several calls to police office to help for me and ask for the local government to assist with me. But the situation has still not any change and let me feel very disturbed.
