Man I know you are asking the question about how to get piece in between them. Other than separating them, I don't have a good answer. I will tell you based on experience, overly aggressive dogs end up fighting later, whether it be at a bay, or in a dog box. I don't (and if I were you) I would not tolerate this for very long. The best hunting dogs are focused on hunting, not fighting. If I had an overly aggressive dog, I would not put up with it long. Overly aggressive dogs interrupt learning and behavior of other dogs and should be culled IMMEADIATELY!
x2 that's a big no no in my yard. And u should never ever "let them work it out" u have to show them who is boss around your place. That's your food u just let them eat it
