Cropping is the removal of part or all of the external flaps of an animal's ear. The procedure sometimes involves bracing and taping the remainder of the ears to train them to point upright. Almost exclusively performed on dogs, it is an old practice that was once done for perceived health, practical or cosmetic reasons. Veterinary science states there is no medical or physical advantage to the animal from the procedure, leading to concerns of animal cruelty over performing unnecessary surgery on animals. In modern times, cropping is banned in many nations, but is still legal in a limited number of countries. Where permitted, it is seen only in certain breeds of dog, such as pit bull and bull terrier type breeds, the Doberman Pinscher, Schnauzer, Great Dane, Boxer and Cane Corso. In 2000, veterinarian Bruce Fogle wrote: [D]ogs have their ears partly amputated—'cropped' is the benign word people like to use—for no other reason than to make them look fierce. This is primarily a German tradition, born out of the military origins and uses of breeds like Great Danes, Boxers, Doberman Pinschers, and Schnauzers. This mutilation—I am sorry to be so blunt, but that is what cropping is—is banned in its country of origin, and in most other FCI countries. North America remains the only significant region in the world where ear and tail amputations are still routinely performed. There is no medical or work-related justification for these procedures to be performed on pet dogs. Many dedicated, dog-loving veterinarians will no longer carry out these alterations. Historically, cropping was performed on working dogs in order to decrease the risk of health complications, such as ear infections or hematomas. Crops were also performed on dogs that might need to fight, either while hunting animals that might fight back or while defending livestock herds from predators, or because they were used for pit-fighting sports such as dog fighting or bear-baiting. The ears were an easy target for an opposing animal to grab or tear.
