My pup got his tail broken at one point and it had to be cropped in the very middle. The hair hasn't grown back at parts and it looks rather "Frankenstienish," but you know what? He doesn't give a crap how his tail looks. As a pet owner who cares about my animal, not about its looks, I don't care how the thing looks.
If someone offered me the opportunity to make his tail beautiful again and it only required his having to go through surgery, I would immediately say no. There's no chance I would risk an animal's health for a vain surgery that they don't even care about.
