Your dog is getting demanding, huh? LOL. I've seen this and they can get obsessive compulsive about it. It can take about 2 weeks to modify a behavior if you're consistant and stick to your guns. Is it a ball? Put it away and a couple of times a day, you take it out and YOU decide when you're going to play that game. Do it for a little while and put it away. If it's sticks, and he brings them to you, just ignore him when he's demanding. If he's bugging you, you'll have to completely ignore him. Don't look at him, don't tell him to shut up, (lol) don't do anything. Go about your business and put up with his whining or barking or whatever he does but ignore him. In addition, give him a job to do. Put him through his paces of obedience skills. Do you work on basics with him? Do you take walks to tire him out? In general, be careful that he isn't whining or wanting something and that you're responding to his demands. You decide everything; when he eats, when he gets a toy (which he doesn't need 24/7) and when you'll put away the toys. You decide when you'll do whatever it is you do with him. Don't react to his ordering you around. LOL. Let us know how he does.
