Although I don't agree with purposely severing the tail of a perfectly healthy fish but haven't you seen Doberman Pinchers with cut off tails and propped up ears?
I don't agree with cosmetic surgeries on pets but some of those do serve a purpose. Hunting dogs often have docked tails because they don't get painful burrs. And dew claw removal saves the dog from potentially ripping them off in the future. But if your dog is going to enjoy a comfortable life on your couch I don't support surgeries simply to uphold a breed standard.
