Well, seeing as I only have one tailed dog and two with cropped ears, obviously I'm not against it. I think the decision to crop and dock should be left up to the owners/breeders/fanciers who want traditionally cropped and docked breeds.
Having been with puppies before, during, immediately after and days after cropping, I can't call the procedure cruel. Once the anesthetic wears off, they're running and playing and eating as normal. I'm sure it hurts, but when done right and taken care of afterward properly, you truly cannot tell. The anesthetic is what bothers them the most. Makes them cold, shakey, drunk, nauseous... once that's done, they're back to being puppies. Honestly, every dog I've spayed has shown a lot more pain than the 30+ puppies I've seen who were cropped properly and looked after properly. Now, people who take their BYB dogs to stupid vets who don't know anything about cropping, that is something I will never agree with. Aftercare is done wrong, the crop isn't done nicely, the whole thing is just a mess.
As for docking, if I'm ok with cropping, then I'm definitely ok with docking. It's a much less invasive procedure.
With all of that said, if either or both procedures are ever banned (which I hope they're not), I'd still own an Aussie with a tail. Should I decide to have another Doberman in the future, I'd own a Dobe with a tail and floppy ears, but it's not my preference. Especially having recently known a rescue Doberman with a tail who had to have it amputated because she broke it. Obviously that wouldn't happen to all dogs, but it happens often enough. I actually think natural Dobermans are pretty.
I am also not against debarking either when done for the right reasons. Or dewclaw removal, although I don't care one way or the other whether my dog has dews or not. Before having gotten involved with and knowing my Doberman breeder really well, I might have had a different opinion on all of this because I was uneducated and all of these procedures sounded cruel. But now I've been around it and experienced it all, and I'd be lying if I said I had a big problem with any of it.
