One note, as far as docking a dog's tail, there are times and reasons why it is actually advantageous to the dog, that doesn't bother me so much. I definitely am for the removal of dew claws on some dogs (coated breeds whose dew claws are loosely held often have a lot of trouble when groomed, and some small dogs the dew claws grow back into the pads, if not kept up and cause pain and infection). Tail docking and dew claw removal don't seem to cause the puppy more than a moment's discomfort. Maybe that's the case for pinioning a duck, but really my domestic big ducks don't fly and I'd much rather control the flying in my smaller ducks by clipping flight feathers or overhead fencing. I do see why sometimes it has to be done to keep down feral domestic ducks.
