I was laughing at the way in which R2L worded his reply, it was the fiction part that tickled me. But like it or not Jack (and I don't btw) it's commonly accepted by everyone in dogs, that a dog who loses a match either can't go for his Gr Ch title or would lose it if he's already attained it.
Your example of Robert T losing his Gr Ch title was a good one and it's equally preposterous of a dog not being given the opportunity to attain his Gr Ch title if he/she happened to lose one early in their career. An example would be Ch Silver, he waxed a gr ch, lost his second while sick, then went on to wax another 2 grand champions and a champion. But he could never go for a Gr Ch title, or ever be recognised as a Gr Ch because he had a loss on his record.
Anyone who stops to actually think about it for a second, can see it's absurd, but like i'v already said, it's become so commonly accepted and ingrained amongst dogmen, most wont even give it a second thought. It's simply just accepted as the way it is.
I don't subscribe to it but i understand the online sdj has alot of people reading it, so it potentially could have a big influence in the way dogmen think if an article was written regarding this outdated rule. Someone with your writing skills could change the way alot of people think if you ever chose to do an article on this.
