I don't dislike the look of properly cropped ears but I dislike the procedure.

I do think there are still good reasons to dock tails though....my aunt's dog Levi is a Viszla/Pit mix, and his long natural tail wags so hard that he injures it and leaves bloody "Thwap thwap thwap" prints all over the house. I hear about it happening 4-5 times a year.

Since he is an adult, they don't really want to look into having it docked NOW, but if he had it done as a pup it could have saved him lots of pain and vet trips.
