Please see the following reminder from the ASCA Conformation Committee:
A REMINDER FOR JUDGES: Per Section 7.3 of the Conformation Rules judges may not compete on the same day they are officiating if multiple shows are held in a single day. You have the option though of handing your dogs off to a handler to be shown.
An excellent source on how to conduct judging assignments can be found in Appendix C of the Conformation Program Rules. It answers a lot of concerns that you as a judge may have. It also may help to contact fellow experienced judges and ask how they might handle certain situations that may arise during the assignment.
