If you are actually doing it for working purposes (such as, for an Aussie, docking their tail because otherwise cat-tails and brush would rip and snag it) - I have no problem with cropping/docking humanely. But, if you're doing it for no good reason, I do feel it is selfish. =/ I know sooo many people who swear they will never crop again, after cropping a dog, and many that say the same about docking; because it's just needless if your dog is a pet.
