Shelly, I am sorry you are facing this and I hope you find the solution to return peace and peace of mind back to your home. Based on my experience with my 2 boys, I agree that the situation is complicated. I don't believe there is one solution that fits all situations.
Max and Teddy are both strong males. Max is technically the dominant one, but there are so many blurred lines. Max allows Teddy to push him away from his food, from the water, or even take his prime sleeping position next to me. Max will roll on his back to let Teddy have the upper paw in wrestling.
When one is sick or injured, they support and comfort each other. But when fully recovered, the challenge is on! Mostly Teddy challenging Max's status.
When they have less activity and exercise (usually because of the illness and injury), that is when Teddy can be naughty. I can usually distract them, get them to focus on something constructive.
When things get out of hand, I never physically put myself in between them or try to tear them apart. I raise my voice "Nooooo!" and stamp my feet if necessary. This makes them stop. I give them a few minutes to cool off and then we do tricks/obedience exercises for kibble.
If Moka and Mylee engage, try breaking it up by making noise.
I agree with the article that the humans being in the room has something to do with it. Max and Teddy are quiet as church mice when they are alone, as video has proved to me, although I have read of other dogs attacking when alone. Sometimes when they are misbehaving, wrestling too hard but not all out fighting, I withdraw my attention and announce that I am leaving. That makes them stop.
