Key to working through this for now is NOT SHOWING THE DOG ANY REACTION to his bratty behavior.
Also in my experience if dogs cannot breathe they have a hard time growling. And you bet, if I had a problem this serious, the dog would learn VERY QUICKLY that his "master plan" of having and controlling all the resources in your home was rapidly coming to a screeching halt.
I would set this dog up dragging a line, and I would begin working him with a slip collar. (IMPORTANT!!!! NEVER allow a dog to drag a line, ESPECIALLY ON A SLIP COLLAR, if you are not paying DIRECT attention to him. NOT EVER) Make the line long enough that you don't have to go so close to him to get the end of it. When he takes the article I have set him up to take, I would reel him in quickly. I would not make eye contact. I would raise him up with the line to a point at which he must make an important decision. Hold and growl, or breathe.
I would do this quietly, calmly, and the INSTANT the dog dropped the object, I would release the pressure JUST ENOUGH so he can take a good breath, and I would briskly walk him away and strongly food reward him.
I do not use these methods often, or lightly. However, this dog is looking at DEATH if this situation is not resolved. It is time for some backbone, and some gloves off real life tough love for this guy.
