Might be more open to change if their tails conformed, but every un docked cocker I've met has had a drastically different tail. People would have to be breeding specifically to fix that.
And that's just yet another problem with docking/cropping bans. Now instead of focusing on other far more important aspects that need to be improved upon in a breed, breeders suddenly have to start trying to breed for proper tail and ear sets. My dobe breeder/friend went to Crufts last year and this year, and talked to quite a few Doberman breeders there about their thoughts on the tails and honestly, it didn't sound like the majority were too thrilled with the ban at all for lots of reasons, but mainly due to the above. They felt very much the same about the ears too, many of them.
Personally, it's my opinion that if you don't own or wish to own a traditionally cropped/docked breed, then it doesn't
really affect you and you should let those of us who do own them decide what to do about ears/tails for ourselves. You're more than welcome to your opinion, as we all are, but it seems most of the people against it seem to be those who think they know what it all entails, but really don't unfortunately. I
have seen pictures of completely "natural" Dobermans that I've liked, and would still own Dobes if C/D were banned here. That said, I
much prefer cropped and docked for various reasons.
