Agressive Behavior

My girlfriend moved in with me with her 3 year old Maltese. He starts to bark when the phone rings early in the morning. He starts to bark at me when I get up to go to work. He starts to bark when I approach my girl friend when she is sitting on the couch. Basically the dog thinks he owns the house. He is not afraid of and I am afraid I might kill him. I have had dogs all my life and have never seen anything like this one. Any advise will help.....
