I'd agree with that on that aspect of the ear thing you mention.
It's funny on the tail thing: I've been looking into other breeds like the Cane Corso. They have docked tails, but most of them are too long for me, aesthetically. The standard says dock at the 4th joint if I'm not mistaken, but I see some tails that are 5 or 6 inches long. Even 4 inches long is too long for me – this, especially since I see so many Corsi that are so waggy with the tail. I detest that look – the rapidly wagging, silly and gay (a technical term) docked tail. I also see the same in the Boerboel. So if I were to get one of those breeds, I would try to get the breeder to either give mine a nice short dock (which I understand is almost not possible because they don't know which dog is going to which home at that age) or just leave the tail intact! That said, I know that goes against the breed standard and I know how I feel about people saying they want things their way when it comes to the Doberman. Hmmm.
I'm hesitant to say this, but I also have been thinking about the topic of docking in the Doberman. I've heard it said that the tail helps dogs balance, and I believe it. I can tell you that for some reason, Oji falls over fairly often when he's running around and juking this way and that, and stopping and turning. Still, I realize that tail docking serves some functional purposes as well.
