Here is the breakdown of the Labradors being shown the 31st. 41 is the total number of Labradors, then 14 class dogs, 21 class bitches, and 6 male specials, and no bitch specials (a special is a dog that has finished their championship in this venue), the last number is a non-regular class entry, such as veterans classes and Hunting Retriever classes.

The Judging program will probably be published about a week or so before the show, which will also have ring numbers and times, so just keep an eye out on the Roy Jones website for that information.
Edited to add: This is the page you will want to go to to see if the Judging program has been published yet. Like the other shows on this page, a live link will show up for this show when they are available. Request Rejected
