Cropping ears is like circumsising a baby. I myself am circ'd and its weird to have a circ'd dog walking around so I believe in cropped ears I had to do it so he has to. Just kidding I hate cropped ears on certain breeds but they do make others look sharp. Purely cosmetic provides nothing but looks and in a defensive situation opens your dogs head open to damage that the ear might have been able to take and prevent head damage. To each is own. Most old guys still do it a tip is to look for those who work on livestock not just pets.
