Pros: - You'll look like a tough yuppie. If you wear the right cloths, you might even look GANGSTA. Cons: - It serves no functional purpose. People who work or game their dogs do not crop their ears. You are putting your puppy out of commission for a month. During this month it can not socialize with other dogs. Notice the same people telling me to mind my own business are the same ones that swear by the mantra "pit bulls can not be around other dogs, they are too dog aggressive; NEVER trust your pit around another dog." Your puppy will aggressively defend its head during this period, a period of intense learning. This means it will bite you, your family and other people's kids if they try to pat its head. This behavior will be ingrained and follow the dog for life. It will forever be weary of people touching its head because of how sore its ears were for a months after you mutilated it. This can create huge behavioral problems. Your dog suffers physically, mentally and socially because you like the aesthetics of body mutilation. Notice that none of the proponents of cropping work their dogs. They couldn't afford to forfeit that much training time.
