I have never seen them hunt in packs here in West Virginia(not to say they don't) I once had a herd of Red Angus and right in the middle of the afternoon,I seen one in the middle of the heard looking at a potential calve/meal,he went to the woods and buy the time I got my gun,he was no where to be seen. I had a Yellow Black Mouth Cur/Leopard Cur mix dog and he had a path beat across the woods that night,because he kept hearing the darn thing and the cattle carrying on,I believe that cur dog kept him out of the cattle that night and probably saved some calves.
