I totally agree with you Sobe....... The reason today is cosmetic and to follow the breed standard. In a lot of countries in Europe when they banned docking and cropping, they gave the breeders of those breeds a certain amount of years to learn how the breeding lines they use were in concern to the ear and tail issue. To say that it makes it easier for breeders to dock, is to me to say that, it is one less thing having to take into concideration when you breed. All breeds with uncropped tails and ears have always had to weigh the look, length and how the tail is carried into their breeding program. And as with other physical defects that would make a dog not suitable for breeding so does an incorrect tail or incorrect ears. Just that when they are being altered the breeders never had to pay any attention to if the ears were too long, too short, crocked or not. Tail too short or long or carried over back when should not be.
I have sympathy for the docked tails on for say boxers though, they have the hard hard tails that easily make for a "happy tail" but the danes for example do not have docked tails and theirs are just as bad. Mostly you get used to dealing with those tails but sometimes it goes bad and you have to amputate a bit off.
And yes it may be easier to keep clean, but with having dogs or any other animal for that matter, grooming comes with the ownership.
