Boxer Booster
I know you get an extremely aggressive animal from time to time, but my point is it usually takes some encouragement for it to turn violent. Not saying the dog couldn't get that way on its own, but two dogs acting this way, and Boxers on top of that? I watch my boy and girl in the yard and while Beau barks, blows, and chases every sound he hears, Stella usually can be found sunning on the deck or just sleeping in the yard when they get there precious outside time. One bad apple wouldn't create another one just by coexisiting together. In the end this is just my opinion from what I have seen and especailly since you would be hard to find violent or vicious dog and Boxer in the same sentence very often.
