Hi Jenny
Looking at the schedule it looks like there will be seven rings. The order in which the dogs are judged follow the schedule....judging starts at 10.00am in ring 2 cockers first, American cockers and so on.
Just make your way to your ring when you get there and set yourself up. When judging starts the steward will call the class, you just enter the ring when your class is called. You can buy a catalogue when you get there from the secretary' table which will tell you your ring number, tell the steward your number and he will mark you as present in the catalogue and give you your ring card.
