I've been watching some of the breed judging at the 2014 Westminster Kennel Club conformation show online and I noticed that there are two stewards in the ring. Any of the other dog shows that I've been to have had a single ring steward (I've shown at AKC, CKC and IABCA shows, and attended but not shown at UKC shows). Looking at the judging program for the show, there are indeed two stewards listed for almost every ring.
So, why does the Westminster KC show use two stewards for most rings? And in the few cases that they only have one, why are those rings different?
