Tail docking in sheep is a practicality. If you only have a few sheep I believe you should be willing to clean them up, but when you have a sheep station with millions of sheep then tail docking is the only way to go if you don't want to have your sheep dying from flystrike all the time, you can't wipe the bums of a million sheep. :)
