I have just found some rules:
NEVER COME BETWEEN THE JUDGE AND YOUR DOG
Always be polite to the judge, steward and other competitors, always be neat and clean in appearance and be dressed to suit and complement your dog eg if showing a black dog you would never wear black, good colours to go for are white, cream, tan or pale pastels. Also high heels and revealing clothes are not showing your dog off any better, girls are advised to either wear a trouser suit or skirt depending on how large a breed you are showing, boys are advised to wear a smart suit or waist-coat, ties are optional for preference.
Ring Turns

Inward Turn - The dog and handler turn in towards one another and move off in a different direction, the handler changes the lead to the other hand.
