Do you want to show them in obedience or a breed show?
If in a breed show they must be Kennel Club registered, unless you only want to do companion shows. Your starting point would be to find a club near to you that holds ringcraft classes. This will show you what is expected of you and your dogs in the ring.
If it is obedience, then you should look for a club teaching competitive obedience. To fnd out about classes in your area give the Kennel Club a ring.
Hope this helps
