It is not a standard for that breed and not needed to show. It was originally done to prevent the animal from getting hurt in dog fighting and while out hunting wild boar and such. The breed is also illegal in many countries still and as a matter of fact is still illegal in NYC if living in housing units.
As far as cropping goes this should sum
It up.... But everyone has their own opinion on what's cruel.
"Most commonly performed on dogs, it is an ancient practice that was once done for perceived health, practical or cosmetic reasons. In modern times, it is banned in many nations, but where legal, it is usually performed for cosmetic reasons, usually related to show grooming. It is seen only in certain breeds of dog such as the Pit bull, Doberman Pinscher, Schnauzer, Great Dane and Boxer.
The veterinary procedure is known as cosmetic otoplasty. Current veterinary science provides no medical, physical, environmental or cosmetic advantage to the animal from the procedure,[1][2] leading to concerns over animal cruelty related to performing unnecessary surgery on the animals. In addition to the bans in place in countries around the world, it is described in some veterinary texts as "no longer considered ethical."[1]
But hey it's your dog. and you didn't feel a thing right?
