I thought that too. You'd think they'd vet check them beforehand to make sure that only totally healthy dogs qualify to represent the breeds. I know that not everyone agrees with it, but it's only for the good of the breed. It must be disappointing for breeders who've previously had successful dogs who now can't be entered though.
I'd also have loved to have seen the breed judging. I suppose they can't show the entire day on tv though. I'll definitely have to go one year. I know a Mexican hairless breeder who enters her dogs every year too, I looked after them.
