Why do you want to crop your dog's ears? I find it pointless, you want the look and you are willing to put the dog through the pain for your vanity. It's not like you have a hunting dog that would benefit from this, you are simply doing it to make your dog look tough. You make your dogs wear those spiked harnesses and now you wanna crop your dog's ears. With all due respect you are not helping the image of the breed by doing this. Everyone in the world hates pit bulls and see them as vicious animals, going out of your way to make your dogs look tough is lame in my opinion. I have nothing personal against you but I just think you should focus more on working out your dogs, and feeding them the proper diet instead of focusing on making them look TOUGH.
