Ear cropping surgery requires precision and skill in order for the ears to stand up and appear as intended after healing. This procedure must be performed by a veterinarian and is best done by one with experience in ear cropping. Dogs must be under general anesthesia for ear cropping surgery. Ear cropping is generally performed on puppies between the age of eight to twelve weeks. After surgery, the ears are bandaged and propped up so they heal in an erect position.
