A removable nose bug will work, but only on cattle that are just disrespectful. If they get shook up and go nuts the bug is worthless and just gets their adrenaline pumping that much harder. Saw it happen at a little jackpot a couple of weeks ago - big strong kid with a nutso steer going to the scale to weigh in and the nose bug didn't even phase him. Ran off and they had to get him into a pen and just leave him there. Basically, if you have a steer that is gentle enough, but has figured out how to push you around or stick his head down and go wherever he wants, the nose ring or bug will work to keep his attention and that is about the only time it will work.
