I guess I was thinking along the same lines as what Dawn just said. How do you know the teeth clipping made any difference if you started rotating at the same time.
I would also like to mention that this article is about 30 years old. 30 years ago chins were rarely pets, a top chin from 30 years ago would be laughed off the table now. 30 years ago their were a lot more big ranchers, a lot less small ranchers, and much fewer mutations.
I don't know about MCBA but anyone is allowed and encouraged to submit an article with ECBC, everyone should feel free to do so. You can write an article about why you don't think people should clip teeth. About how you got started, about a show you went to, about how people helped you get started, about how you think more or less regulations should be put into place... what ever. If they are reprinting articles it's due to one of two reasons, it's an awesome article, or they don't have any new articles to print...
