I must confess, I am not a 'tail' person, I do prefer my dogs sans tail for a number of reasons.

However, since you don't know how all the dogs will look once they mature, you might consider doing only the one's that look rottie.

When my Queensland Shilo snuck out and caroused with the neighborhood curs, I dutifully docked the three pup's tails. However, once 'Red' grew up (the one pup I kept) he was SO ungainly looking without his tail!! Apparently he took after his yellow lab pop too much, and he definitely would have looked better with a tail!
