I do like cropped danes and boxers, but I also love natural eared danes and boxers. ike Classic... his crop makes me drool!
I looooooove the cropped look, I feel that Classic is much more expressive than Titan. I'm ok with natural as long as the ears lay right, I'm constantly fixing Titan's when one decides to go flying nun on me. I wouldn't crop a pet of any breed however, it's not worth the risk of surgery for me.
Docking is a necessary thing in my opinion for some breeds. Anyone having to deal with happy tail knows how much of a pain in the butt that is and if the dog is going to end up with a tail amputation either way, I'd much rather have it done at 3 days when it will heal right than at 1.5 years.
