I saw someone with a blue at the last show i went to. They didn't win, but everyone was too busy gaping at the dog's sound structure to laugh or anything. The one person who did react rudely was met with severe disapproval and in the end, the dog came in second ( only lacked first due to coloring). But it really depends on the particular people at the show. Some are relaxed and fun. Others are quite rude and put you down.
