Personally I am totally against cropping a dog's ear of any sort, except for medical reasons, I think it is against our law here and rightly so., sorry but that is my strong opinion on this.
Ditto thank goodness it is illegal here. A Dobermann came into our local shelter and someone had done a home job on his ears, they looked awful.

Docking is now illegal here aswell, now maybe the RSPCA can get off their butts and do something about all of the abuse cases .
