You have yourself a teenager on your hands. You - seeing as he's fine with your husband - need to take him to an obedience class, and do the exercises to establish that you are in charge, not him. He's testing the boundaries and limits, like all teenagers do, so it is time to set some firm boundaries. Be prepared to repeat things over and over and over and over - Bullies are known to be - well, stubborn to say the least! You need to be the "big dog" here! He will eventually settle down, but the time is now for some serious obedience work with you and him!
