I agree with gary.. find a way to communicate to it that its constant plea for attention WILL NOT be heeded to.. my dobermann had a similar trait (he would sneak under my hand and have my palm placed on his head).. but I didn't mind keeping my left hand on his head for a while I worked by my right, and after a while he used to doze off.. but I used to discourage him if he demanded too much attention, and he used to accept it. it should always be you who should decide whether you are attending to the dog or not.. never entertain a dog dictating what you must do, howsoever sweet its persuasion may be.
