I’ll just throw my .02 in here. If you discipline him and he becomes aggressive, you absolutely must take it to whatever level you need to UNTIL he submits 100% to you, This may mean you laying on top of him pinning him down for up to an hour at a time. I have broken several of my own dogs and several friends dogs who were a little too aggressive.
Playing rough and then start taking it too far is a big one. Dogs need boundries and they will remember them after they are enforced only a couple times. A really difficult dog needs more frequent reinforcing.
Here is a big question, when your dog gets aggressive when you physically correct him, what do you do? Do you back away? Pin him down until he is 100% submissive, Try to hold your ground while talking him down? If you do anything other than plastering his ass to the ground and making him submit to you, then he has just owned you.
He knows you are afraid of him and no matter what other silly commands you make him do, he knows when it’s go time, you will back down. Now why I wouldn’t be afraid of your dog is #1, he is not trying to kill you or seriously hurt you, he hasn’t lost his mind or anything. He is basically asserting his domanance.
If you are lying on the couch and he really wanted to hurt or kill you, he would be breaking skin all over the place with his bites and he might even try going for your neck. This is a good thing though, regardless of his growls and snapping bite attempts, and you may take some bites to the hands and arms, but seriously, if you want this corrected, when he gets aggressive, You grab him by the scruff on his neck, pull him down to the ground hard and mount him.
If you grab him with your right hand, circle a little to his right, this way when you drag him down his head is facing away from you, you then bring your left hand and forearm across his neck and under his chin. You apply pressure down on his head/neck with your forearm and elbow and pull his head back like into your leg with your hand.
You should have a good control on him now and unless he really outweighs you you will be able to keep him pinned down like this with nothing more than your weight. With your right hand once you have the head controlled, you just keep his feet from gaining traction on the ground, keep the off the floor, thats where his power is, and also use that hand to keep him from rolling into you, If he starts to roll into you, just grab one of his legas and push it away from you (push it into his roll).
Now this may sound dangerous and maybe even a little extreme and I have to reiterate, you may get bit, especially when you first grab him. Unless you are really fast, and do it with the intent that there is nothing that will stop your takedown and dominance of this dog. Unless you cat like that, you probably will get bit.
If you have at your disposal, controlled rage, I would definately use it here. Snap on him but only with the intent of completing the disciplinary move I just described. Don’t try to hurt him, don’t kick him in the ribs. If you really love your dog and you are truly not afraid of him and your not afraid to get possibly a little injured, this will break him.
I’m sure if you searched around youtube you could find video of the technique I just described to help illustrate my points.
