There are some legitimate reasons for tail docking, I guess especially on some sporting/hunting breeds, but if it isn't going to serve a specific function I would rather see a natural tail.

Ear cropping I totally don't like or agree with. The UKC does not crop their dogs' ears even for the show ring. I know it used to be done in some fighting dogs to help prevent an ear getting bitten or torn, easier for a dog to grab ahold of a floppy ear and very painful as a lot of nerves in the ears. I much prefer natural ears. I think some people get used to seeing the prick ears and like them better. Just as if I suddenly saw a purebred German shepherd with floppy ears I probably wouldn't prefer it over pricked ears, but a GSD ears are natural and that is the key. It isn't natural, there's no reason other than cosmetics, unless a dog is going to be fighting... and if that's going to be happening that's a whole other much more serious issue.
