Is your dog from Haus Juris? (looking at your sig) If so, I'd ask them what they do. They will be at the show for sure with a large entourage.
I show in these types of shows, but to be honest, I don't really put any work into grooming or my dogs' coat. A lot of it depends on the time of year anyway, I can't really control when the coat is thin and flat vs. full. Usually I bathe the dog a few days before the show (not the day before or day of b/c sometimes the skin will flake a bit, and it always gets the hair blowing out so I want a few days to brush). I use a high velocity dryer to blow out the undercoat and fluff the coat. The day of, I just do a once-over with the rake brush, fluff here and there with a pin brush, and that's really it.
