I don't show, but when I can get to spectate at a show, if the GSD ring is nearby (it usually is, as I go to watch other pastoral breeds) the noise from the GSDs is often so great that I see it affecting other breeds in rings nearby. Hard for the handlers to concentrate when there is whooping and yelling at their elbow. It's almost as though they have a show of their own within a show.
And before anyone says that show dogs should be bombproof enough to cope with anything like that, just stand near the GSD ring and imagine you are handling your dog in the ring next to it.
