Ear cropping is a personal choice, and like yourself, I prefer the cropped look........but I also can take care of the aftercare myself. (I don't need to take the pup to the vet for re-tapings, etc). From my personal experience (and I've had 6 cropped through the past 7 years), the first couple of days, there is SOME discomfort, but not alot. The worst part is shortly after cropping and if they bump their ears on something. That was the only time it seemed to bother them. (Besides the itching while healing) There are many vets that don't crop, many vets that crop, but they truly don't know how to crop properly (estimate the length & width they need to take off, etc). People must be very careful and really research to find a vet that knows how to crop properly.
As far as tails........that is why they are docked at 3-5 days of age. The bone in the tail has not hardened. They do squeal, but just for a few seconds then no more. Same with dewclaws being removed. You will NEVER convince me not to dock a tail. I have seen far too many other breeds with the overall same type of tail that a boxer has that has broken their tails because of banging them around. Broken tails are far more painful that the couple of seconds it takes to dock a boxer puppies tail. We have a few dogs at the clinic I work at, when the dog boards, we have to bandaged their tails before putting them into the runs. If we don't, they hit the sides of the runs so hard with their tails, they will bleed.
