You should also be properly dressed and groomed for the ring. Most men will wear a coat and tie, even on the warmest of days. Have your equipment organized on the day before the show. Give yourself plenty of time, particularly if you are unfamiliar with the show site. Allow yourself at least a couple of hours for unloading, parking, and grooming.
Many dogs get excited or nervous when they first arrive at the show site.
Give them time to settle in. Find your show ring and pick up your armband. Ask the ring steward if the judge judges in catalogue order. If so, note what position you are in the class and if you know your competitors, make a mental note of who the dog is in front of you. Two minutes per dog is the average amount of time it is expected to judge a dog, but some judges are slower and some move along very quickly.
