Dogs are so much better than people, truly mans best friend. My breed of choice is a Cocker Spaniel. Had one that passed away and found a rescue that specializes in them. Found a great new dog, so sweet and loveable, and already housetrained!
As far as nipping ears, dogs tend to heal very quickly, especially when they are being treated. My dog had two cracked teeth that needed to be extracted. I am sure it was uncomfortable for her for a few days, but within hours of bringing her home, her tail (whats left of it as it was cut as a puppy) was wagging and she was her normal self.
In this country, most young male infants are circumsized, they certainly dont have a say. Kinda the same thing. I would say most men who are, are probably glad they were, and dont remember having it done.
