Lewis, with all due respect, a high prey or fight drive is infact not the desired traits of a livestock guarding dog. My WEBs are very non dog agressive, however, when challenged by a direct threat, well that's a different story. Keep in mind, a number of old school game bred APBTs are infact non dog agressive, they would even turn away from a challenge of a dog on the street as if it would be beneath them to engage in battle with such a cur.
