Awww Cute!
I agree with everyone else...please don't crop her ears. It IS painful for the dog. It's basically just for looks, I think they look better with natural ears anyway.

"There is NO proven medical benefit to cropping, It has never been scientifically proven that it will cut down on the amount of ear infections by increasing ventilation of the ear canal. Keeping the ears clean from dirt and debris is the job of every dog owner, it's basic maintenance, regardless if the dog is cropped or uncropped."
