Leave in plenty of time and get there early. Find your ring early. When you know where everything is, go outside and encourage poop and wee. You don't need to take anything other than a couple of brushes and the lead with dog attached :-)
I always over prepare, I take 30,000 brushes, 3 leads incase of emergency etc, but I have learnt to take 1 slicker brush, 1 comb and 1 small pair of scizzors. This is all I ever use, the worst bit about showing is all the stuff you have to cart about. I put it in a rucksack with a bottle of water and collapsable bowl for the critter, and money for a bacon cob :-) then I always have 1 hand free.
When in the ring, use the whole ring for moving
Good luck, where you at, who's judging
