If you answered yes to more than three of these,  you are not in charge, HE IS.  You have to get control before you have a real problem on your hands.  Dogs, especially Apsos respond to a power vacuum by asserting their own dominance.  If you fail to teach the dog his place in society, he will assume control and teach you yours.
