Hey everyone. My Australian Shepherd has just turned 2 years old and my wife and I are getting a little guy to keep her company. We're getting a doberman pup and he should be ready to pick up the middle of this month so I have a quick question. They're going to already have his tail docked, but they're leaving the ears natural. Is there any medical benefit to having their ears cropped, or is purely for aesthetic appeal? Are they prone to ear infections if it's not done? I'm just looking for some of your opinions.
