I believe it's because they're so often trained harshly/or taught to act aggressive but not given a way to release that energy in a healthy.
I find breeds like sheppards, pits, rotties, dobes etc are often trained harshly and handled wrongly. Even smaller dogs who are owned by people who don't allow them "to be a dog" are stressed out and act aggressively because of being handled incorrectly.
