That is one thing I do not like about showing in comformation. I had a great Doberman female, She was perfect in every way! Would have been a great show dog. She slipped on the ice and broke a few teeth and they had to be pulled. So she was missing 4 teeth. So then we could not show her. If showing is to show the breed, then the owner should be able to show an altered dog! My point is that things happen and sometimes a dog needs to be altered but it that dog is perfect example of the breed then you should be able to show. Just my opinion.
